Hi there!
I am having trouble with Serializing my classes into an XML file.
My classes are as follows:
**************
public class Class1 : CollectionBase
{
public Class1()
{
Class2 newClass = new Class2();
this.List.Add(newClass);
}
public Class2 this[int i]
{
get{return (Class2)List[i];}
}
public void Add(Class2 C)
{
this.List.Add(C);
}
}
public class Class2 : CollectionBase
{
public Class2()
{
this.List.Add("Hello");
}
public string this[int i]
{
get{return (string)this.List[i];}
}
public void Add(string S)
{
this.List.Add(S);
}
}
**************
Now they do serialize, however they do not serialize as I need them. The result looks like [I removed the namespace bits...]>
<?xml version="1.0" encoding="utf-16"?>
<ArrayOfArrayOfString ... >
<ArrayOfString>
<string>Hello</string>
</ArrayOfString>
</ArrayOfArrayOfString>
I need the names to be more user friendly instead of ArrayOfArrayOf... etc. A further issue I have is that my actual application consists of >
Class1 : CollectionBase
contains Elements of Class2
Class2 : CollectionBase
contains Elements of Class3
Class3 : CollectionBase
contains Elements of Class4
Class4
I want the serialization to NOT include the Class4 elements of Class3 however it does and I can't find a way to stop it?!
Does anyone have any ideas on how to correct this?
Many thanks,
Tom.

Use the XmlArrayAttribute and XmlArrayItemAttribute.
|
|
|
|
|
And use XmlIgnoreAttribute for the items you don't want it to serialize.

Thank you for the reply, Dustin!
I have tried to do this with no success.. If the classes contained a collection such as an ArrayList, this does work but as the classes are derived from CollectionBase, I cannot find a way to achieve the same results.
For the Class1/Class2 example I gave, where would I put the XmlArray attributes? Could you supply some code as an example?
Thanks,
Tom.

Ah, ok. I see what you're doing. Well, there's not really a quick and easy way to fix this. The XmlSerializer really is not that intelligent. One thing that I do is implement the IXmlSerializable interface whenever the XmlSerializer can't do the job. Is this an option for you? The alternative is to structure your classes in such a way as to be more conducive to the XmlSerializer.

Hi Dustin, thanks again for the reply!
I realised that by using the XmlSerializer, I would have to 'compromise' a little on the class structure design and I have tried to do this as much as possible but I unfortunately have gone as far as I can. 
I should be able to implement the IXmlSerializable interface although I must confess, I've not done this before. I'll do some research now and see if this will help me out! 
Many thanks for your help!
Tom.

The XMLSerialiser can only handle Arraylist or arrays. It says that in the docs somewhere.

Hi leppie,
Thanks for the reply.. That makes sense and fits in with what I have seen. Thanks for confirming!
Tom.
|
|
|
|
|
There are easy ways around any problems with types just using properties to get/set underlying non serializable types with TypeConverters.
|
|
|
|
|
Hi leppie,
Could you possibly detail an example using the original class structure examples I gave?
It would be much appreciated.
Thanks,
Tom.

It depends how you want the XML to look, show me what you want. And what will be the container of the 'outer' collection?

Isnt that just: Class4[][][] ?

Hi Leppie/Darren,
I think I have got this sorted now.. I have utilised the IXmlSerializer interface and with a small amount of tweeking, it seems to be sorted.
Thanks for your help!

how do i get a value in datagridview ?
cellValue = dataGridView1.Rows[0].Cells[1].ToString(); ??? how do i change this line ?
help please ...
thanks, bye.

If DataGridView works similar to DataGrid, then you
can use myDGView[row, col].ToString().

I am new in C#.In doing a windows application
my form1 class has a Fee class that uses static methods,
i would like to use new_method in form1 class in the Fee class
i know i cant access methods in form1 class
,is there a way i can access form1's new_method without creating form1 object in Fee class?
public partial class Form1 : Form
{
public delegate void new_foo_delegate();
private MyUserControl mycontrol;
public class Fee
{
public Fee()
{
}
private void button1_Click(object sender, EventArgs e)
{
Thread t = new Thread(new ThreadStart(Run));
t.Start();
}
public static void Run()
{
invoke(new new_foo_delegate(new_method));//NB the method in my main
}
}
public Form1()
{
InitializeComponent();
}
public void method()
{
mycontrol.Dipslay(txtbox);
}
void new_method()
{
textBox1.Text = "Hullo";
}
}
}
nb this is just an example
hope my question is very clear
thanks
regards paula

Sure, as long as an instance of Form1 exists, you can expose that instance to the Fee object (that would be a broken design) any way you like and then call it's new_method() member. You cannot call new_method() without an instance of Form1.

If you are calling a non-static method then you need an instance of the class that contains the method. What exactly are you trying to do? Perhaps there is a better way?
One thing you might think about is could you have a static member in your fee class of type form1? That way you'd only have to create an instance of form1 once in your fee class.

hi all,
I'm having a bit of an issue here and maybe one of you guys can help me out .
I'm looking for a way to return all COMPONENTS in a form during run-time, and i mean components including all controls , menu's, custom controls etc.
As you all now a control is a component but a component is not a control.
You will probably think that i'm somesort of idiot , but i'm not (at least i think i'm not), and i've tried every possible way to reach my goal:
1) tried to convert the form as container -> didn't work
2) adding the component that needs to perform above actions and using it's own container as componentcollection holder doesn't work, bcause the container returned is the component itself.
3) returning a menu's container -> doesn't work -> it always returns nothing

Can you do something like this?
List<IComponent> components = new List<IComponent>();
foreach (object obj in myForm.Controls)
if (obj is IComponent)
components.Add(obj as IComponent);
You might have to do it recursively though.

That won't work because, as the original question mentioned, all controls are components but not vice versa (Control derives from Component). Components are not in a form's Control tree.

How about reflection then? You can do a GetMembers() on the form's Type and look for fields. See if that field type is an implementation of IComponent, and add it to the list.
List<IComponent> components = new List<IComponent>();
foreach (MemberInfo mi in this.GetType().GetMembers()) {
if (mi.MemberType == MemberTypes.Field) {
if (mi.DeclaringType.GetInterface("IComponent") != null) {
FieldInfo fi = mi as FieldInfo;
components.Add((IComponent)fi.GetValue(this));
}
}
}
I haven't tested this code, but it should be pretty close. Last modified: Wednesday, May 31, 2006 12:25:05 PM --

Hi Dustin
tnx for the reply, unfortunately it doesn't seem to work. Maybe i should dig in a little deeper, but i don't think this can work because imho components aren't fields . Tnx for the effort anyway.
Maybe i shoud try another approach. If I just could get the correct container from my component (ie. the form it's hosted on but then defined as container instead of form).
BTW: i'm still using .Net 1.1 and not 2.0, just to avoid confusion.
