I'm trying to do this:

SomeRandomMethod(blah, blah, new { id=1,mystring="text"})

and when I get here:

public void SomeRandomMethod(dynamic obj)
{
    int id = obj.id;
    string text = obj.mystring;
}

the code throws exceptions because the properties don't exist.

Some might say, create a class with the same properties and cast it in the method, but then what's the point? If it's gotta be strongly typed, then it should be strongly typed where you're creating the instance (IMHO).

I used the latest .NET release with the latest version of C# (in WPF), and it works for me.

I'm using .Net 4.5 and MVC (not that the framework should have anything to do with it).

It's probably just you simplifying it for the question, but why are you calling the method with three parameters, when it only takes one? Smile | :)

I was just trying to illustrate the way I was trying to use the construct. If I instantiate it BEFORE calling the method, everything is fine. If I instantiate it in the call to the method (as I showed), it fails. I can't instantiate it before calling the method because I'm calling it in a MVC view.

While we're batting this around, I've gone ahead and created a series of classes that support the desire parameters. This is part of my over-arching effort to over-engineer some extension methods. Smile | :)

There's a static helper method on the System.Web.Mvc.HtmlHelper class:
public static RouteValueDictionary AnonymousObjectToHtmlAttributes(object htmlAttributes)[^]

That delegates to the System.Web.WebPages.Html.HtmlHelper class:
public static RouteValueDictionary AnonymousObjectToHtmlAttributes(object htmlAttributes)[^]

That uses the internal System.Web.WebPages.HtmlAttributePropertyHelper[^] class, which inherits from the PropertyHelper[^] class, which finally uses reflection to read the properties of the anonymous type:
protected static PropertyHelper[] GetProperties(object instance, Func<PropertyInfo, PropertyHelper> createPropertyHelper, ConcurrentDictionary<Type, PropertyHelper[]> cache)[^]

If you just want to use the same behaviour, the simplest option is to call the helper method.

If you mean the search history in Explorer: How to Delete the Search History in Windows File Explorer[^] - but this is not a "help me with my computer" site: please ask development related question here in future.

If you don't, then I have no idea what you do mean, and you need to explain in a lot better detail: 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.

Where to start? ... How about formulating your question better? Did you mean "Search" or "Indexing"? Or?

Or is this your Dad's computer; and you're trying to hide your "browsing"?

You wanted "no complex answer"! Laugh | :laugh:

And there are no "simple" answers to simulating pool, snooker, or even billiards. Learning to plan the real game properly at a good quality can absorb huge amounts of your life, because tiny differences cause such massive changes: professional snooker players take years to get to that level, and have to practice 5 ~ 6 hours a day, 6 days a week to maintain, let alone improve their skills.

Simulating that? Not a trivial subject in any way, shape, or form - so there are no "no complex answers" other than "go to Google, and it will serve up some of the complicated ones". Laugh | :laugh:

Seriously, this isn't a task for a beginner - I wouldn't want to try it on my own and I've been coding for 30+ years! I'd need a team of developers, designers, and some professionals on standby to get any reasonable results in a workable time frame of 2 ~ 3 years. Even then, it probably wouldn't be ready for public release for another year or two after that. It's a big job!

That's like saying, "Where can I get a simple diagram of a Formula 1 engine, I have just learned how to assemble a 3-speed gear on my bike". And the issue really is not about C#, it is about the physics of ball trajectories on a pool/snooker table. Spend more (much more) time on some simple projects and learn as many .NET classes as possible first.

Matching Percent Symbol Using REGEX

Hello, I am trying to match a substring which contains the percent symbol using REGEX W character but it does not seem to work. Below is what I have so far.

string inputString = @"#Test{border-top:Solid blue 1px; border-bottom:1% solid black;}";
string escapedString = Regex.Escape("border-bottom");
string pattern = escapedString + @"\:\s?\d+\W(\s?\w+)*\;?\s?";
Regex rgx = new Regex(pattern);
Match match = rgx.Match(matchedCss);
string matchedString = match.Value;
Console.WriteLine(matchedString);
Console.ReadLine();

The REGEX pattern above should have matched the substring

border-bottom:1% solid black;

but for some reason it did not. Please help me resolve this problem, thanks in advance.

You don't need to escape the colon maybe?
And probably not the semi-colon either?
