That's a perfectly valid JSON string. Using JSON.NET[^] to parse it works perfectly:

string json = "[{\"id\":\"0b5a6026-d347-4f8d-94e7-eede0bda6df1\",...,\"timeZone\":\"Europe/Amsterdam\"}]";
JArray array = JArray.Parse(json);

If JsonValue.Parse[^] can't cope with it, there must be a bug in that API.

But then you get a JsonArray and not a JsonObject.
How can I get the values of ["0"]["id"] and ["0"]["name"] when it is not an object?

----found it---
I didn't get it first, because there was only one object in the array, so why could I not create an object from the string instead of an array.
But after I created an array and made an object of the first (and last) item of the array, I could access the values Smile | :)

JsonArray array = JsonArray.Parse(json));
string temp = array[0].toString();
JsonObject firstItem = JsonObject.Parse(temp);
string id = firstItem.GetNamedValue("id").toString();
string name = firstItem.GetNamedValue("name").toString();

Thanks all for your help!

Reflect Generic Property Info

Kevin Marois30-May-18 7:19

30-May-18 7:19

This is a bit long but please bear with me as I'm stuck. This is a C#/WPF app. The problem is C# so I posted this here.

I am creating a Property Sheet user control. Think of the Visual Studio property sheet. The first pass will simply be a two-column grid with a Caption in the left column and a UI element in the right columm (TextBox, CheckBox, ComboBox).

This control will embedded into a larger UI that allows the user to change the settings used int a Testing Application, without the need to recompile the app.

Data
The settings will be serialized/deserialized in an XML file:

<_TestSettingsBase xsi:type="BeadBeatingMotorSettings">
<TestName>Bead Beating</TestName>
<TestType>BeadBeating</TestType>
<BeadBeaterMax>
  <Caption>Bead Beater Max</Caption>
  <Description>Bead Beater maximum</Description>
  <CurrentValue>
    <Value>1</Value>
    <Value1>1</Value1>
  </CurrentValue>
  <DefaultValue>
    <Value>1</Value>
    <Value1>1</Value1>
  </DefaultValue>
  <ValueMax>
    <Value>0</Value>
    <Value1>0</Value1>
  </ValueMax>
  <ValueMin>
    <Value>100</Value>
    <Value1>100</Value1>
  </ValueMin>
</BeadBeaterMax>
<BeadBeaterMin>
  <Caption>Bead Beater Min</Caption>
  <Description>Bead Beater minimum</Description>
  <CurrentValue>
    <Value>0.075</Value>
    <Value1>0.075</Value1>
  </CurrentValue>
  <DefaultValue>
    <Value>0.075</Value>
    <Value1>0.075</Value1>
  </DefaultValue>
  <ValueMax>
    <Value>101</Value>
    <Value1>101</Value1>
  </ValueMax>
  <ValueMin>
    <Value>999</Value>
    <Value1>999</Value1>
  </ValueMin>
</BeadBeaterMin>
</_TestSettingsBase>

In the XML above the base setting class has TestName and TestType properties

[Serializable]
public class _TestSettingsBase
{
    public string TestName { get; set; }

    public TestType TestType { get; set; }
}

Then, each individual Test class will inherit from that

[Serializable]
public class BeadBeatingMotorSettings : _TestSettingsBase
{
    [ShowInPropertySheet()]
    public Setting BeadBeaterMax { get; set; }

    [ShowInPropertySheet()]
    public Setting BeadBeaterMin { get; set; }

    // CTOR
    public BeadBeatingMotorSettings()
    {
        TestType = TestType.BeadBeating;

        BeadBeaterMax = new Setting
        {
            Caption = "Bead Beater Max",
            CurrentValue = 1,
            DefaultValue = 1,
            Description = "Bead Beater maximum",
            ValueMax = 0,
            ValueMin = 100
        };

        BeadBeaterMin = new Setting
        {
            Caption = "Bead Beater Min",
            CurrentValue = 0.075,
            DefaultValue = 0.075,
            Description = "Bead Beater minimum",
            ValueMax = 101,
            ValueMin = 999
        };
    }
}

The test's properties are defined as a generic type property I called Setting<t>

[Serializable]
public class Setting : _EntityBase
{
    public string Caption { get; set; }

    public string Description { get; set; }

    public MyProp CurrentValue { get; set; }

    public MyProp DefaultValue { get; set; }

    public MyProp ValueMax { get; set; }

    public MyProp ValueMin { get; set; }
}

public class MyProp
{
    private T _value;
    public T Value
    {
        get { return Value1; }
        set { Value1 = value; }
    }

    public T Value1 { get => _value; set => _value = value; }

    public static implicit operator T(MyProp value)
    {
        return value.Value;
    }

    public static implicit operator MyProp(T value)
    {
        return new MyProp { Value = value };
    }
}

So far everything works great. The data is serialized/deserialized perfectly.

Property Sheet
This is where I'm having trouble.

The PropertySheet is a DataGrid with two columns. The left column is the property's caption and the and right column has a UI element to display the value (TextBox, CheckBox, ComboBox). So far, I created a small User Control for each type of data I expect to deal with.

For example, for Double, I have a UC called DoublePropertyView. It's XAML is this

<UserControl x:Class="PropSheet.PropertyViews.DoublePropertyView"
             xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" 
             xmlns:d="http://schemas.microsoft.com/expression/blend/2008" 
             mc:Ignorable="d" 
             d:DesignHeight="100" 
             d:DesignWidth="100">

    <TextBox Text="{Binding SettingValue}"/>

</UserControl>

The code behind has a DependencyProperty called "SettingValue" that the TextBox is bound to. Nothing more than that.

I have one small UC for each type of data - double, int, float, bool, string, etc.

Then the DataGrid's right column uses a TemplateSelector to determine which UC to load into the cell.

The PropertySheet UC has a DP called Settings that takes a list of _TestSettingsBase.

Problem
When I set the list of properties on the DP I then need to reflect each of the properties on the Test class and load into the grid only those properties with the custom attribute ShowInPropertySheet(true).

In the code above you can see on the BeadBeating test class there are two properties, BeadBeaterMin and BeadBeaterMax.

I want these two to appear in the property sheet. Notice that they're marked with the ShowInPropertySheet attribute. When shown in the property sheet I want the Caption and CurrentValue to appear.

Here's my LoadProperties code with the problem. I loop through each Test class in the Settings DP and create a model for each. The list of models is bound to the grid

private void LoadProperties()
{
    Properties = new List<PropertyModel>();

    // Get a list of PropertyInfos for each property on the setting marked with ShowInPropertySheetAttribute(true)
    var propertyInfos = from pi in Setting.GetType().GetProperties()
                        let attrs = pi.GetCustomAttributes(typeof(ShowInPropertySheetAttribute), true)
                        where attrs.Length != 0 &&
                        (bool)Helpers.GetAttributeValue(Setting.GetType(), pi.Name, typeof(ShowInPropertySheetAttribute), "IsVisible")
                        select pi;

    foreach (PropertyInfo propertyInfo in propertyInfos)
    {
        // THE PROBLEM IS HERE. I WON"T KNOW WHAT THE TYPE THE SETTING IS AT 
        // RUNTIME. EVEN THOUGH I HAVE "DOUBLE" HARDCODED HERE, I NEED TO GET 
        // THE TYPE FROM THE <T>  SET ON EACH OF THE PROPERTIES
        // MARKED WITH ShowInPropertySheet<br />
        var settingProperty = (Setting<double>)propertyInfo.GetValue(Setting);

        var current = settingProperty.CurrentValue;

        var model = new PropertyModel(propertyInfo.Name, current.Value);

        Properties.Add(model);
    }
}

If it's not broken, fix it until it is.

Slightly tricky to follow, since your generic type parameters seem to be missing from your code blocks.

Assuming PropertyModel is not generic, and the value is an object, you probably need to have a non-generic interface to read the value. For example:

interface ISetting
{
    object CurrentValue { get; }
}

class Setting<T> : _EntityBase, ISetting
{
    ISetting.CurrentValue => CurrentValue.Value;
    ...
}

...

foreach (PropertyInfo propertyInfo in propertyInfos)
{
    var settingProperty = (ISetting)propertyInfo.GetValue(Setting);
    var model = new PropertyModel(propertyInfo.Name, settingProperty.CurrentValue);
    Properties.Add(model);
}

Hi,

I have console application that call some API that is working fine

https://www.xxxxxxco.il/QA/xxxServiceFront/xxxx.asmx

but when i tying to call this API from a WCF Service on IIS EXpress or On IIS in server 2012 i am getting this error:

Unable to connect to remote server

There was no endpoint listening at https://www.xxxxxxco.il/QA/xxxServiceFront/xxxx.asmx that could accept the message. This is often caused by an incorrect address or SOAP action.

why there a difference between IIS express and the console application?

As you haven't presented any code at all, despite this being a C# forum, we're only going to be able to take wild guesses. My best guess would be that your issue is going to be down to identity. The console application runs as your user while IIS is not. I suspect the service is going to expect authentication.

This is not a good question - we cannot work out from that little what you are trying to do.
Remember that we can't see your screen, access your HDD, or read your mind - we only get exactly what you type to work with.

So explain what an "MD" file is - the only one I'm aware of is a Markdown text file, and that's trivial to read:

string text = File.ReadAllText(pathToFile);

Then explain what problem you are having reading and writing it - we have no idea where you are stuck, so we really can't help you yet.
