Hi all,
I have the following scenario. I have a generic static class. Is there a way for me to invoke something like that using reflection. For example. I have a static class with a method.
MyClass<T>.Show()
The item being shown depends on T.
Can I invoke such a method using reflection I have the string (MyClass<MyType>) given to me, but I cannot create an instance of that using reflection (since MyClass is a static class).
Any help is appreciated.
Thanks ahead.
David
Is it possible to invoke a generic static class mthod through reflection.

Hi David.
You can simply pass the generic type specifier to the typeof() call, then call InvokeMember as normal on the returned type, thusly:
using
System;using
System.Collections.Generic;namespace
ConsoleApplication1{
class Program{
static void Main(string[] args){
try{
Type type = typeof(MyClass<int>);type.InvokeMember(
"PrintType", System.Reflection.BindingFlags.InvokeMethod | System.Reflection.BindingFlags.Static | System.Reflection.BindingFlags.Public, null, null, null);}
catch(Exception ex){
Console.Error.WriteLine(ex.ToString());}
Console.ReadLine();}
}
public class MyClass<T>{
public static void PrintType(){
Console.WriteLine(typeof(T).FullName);}
}
}

Yes, you've got it. And yes, you need the 1, although to be honest I'm not sure why. I think it might be the indexer of the generic type parameter

Hi Mark
Thanks for the response. In regards to your addendum, I just want to make sure I understand that correctly.
ConsoleApplication1.MyClass - this portion is my actual static class
'1 - the ' is the backtick, but does the 1 need to be there
[System.String] - this portion is where I will put my actual type T.
Is my understanding correct Thanks again for your help.

Addendum:
To get a generic type when you've only got the string type name, you need to use the backtick operator in the string passed to GetType. In the above code, you'd use:
Type
type = Type.GetType("ConsoleApplication1.MyClass`1[System.String]", true);
