Get the class of a Type C#

[nelsonbrodyk]

Hey All,
I was just wondering if this is possible.

I have a List<x> object, and from this, I need to be able to get x. and then use x's class as the generic type for another method.

ie.

private R GetData<R>() {


//this should get me the type of the generic. ie List<string>, this should return //string
Type listType = data.GetType(). GetGenericArgum ents()[0];

//Call another method with the generic type of the list
MethodB<listTyp e>(args);

}

How can this be done? Right now, I cannot specify the type in MethodB, as I think it wants the class. Is there any way to do this?

Thanks.

All objects have a .GetType() that returns the Type for the object that they are.

When I try and call MethodB: MethodB<listTyp e>, the compiler does not allow this, because it says:
Error 2 The type or namespace name 'listType' could not be found (are you missing a using directive or an assembly reference?

I think it's because it's expecting a class, like "string", "int" etc, I can't give it a type can I?

Well lets say you have:

Myclass fred = new Myclass();

MethodB<typeof(fred)>
//or
MethodB<fred.GetType()>

Either of those should work.

Here is what I am trying to say, because I am not following your reply.

I have a list of string. ie. List<string>.

I want to call a method such that:
MethodB<string> ();

But I won't know what the list type is until runtime. ie.

List<?> myList;

MethodB<?>;

If I get the generic Type of the list, that returns me a Type object.
ie. Type listType = data.GetType(). GetGenericArgum ents()[0];

You cannot go List<listType>, because it seems to expect a class only.

Does that make sense?

Looks like you can do this through reflection and the calling of your own method. Anyone know of a more elegant solution?

[Plater]

Ok I see what is going on then. Yes, you should be able to do that using the System.Reflecti on namespace I think?

[nelsonbrodyk]

Ya, what I did was basically call the method again via reflection. I'm guessing that's really the only way to do it.

Thanks,
Nelson
