Creating Generic object at runtime

[kumar.senthil]

Hi,
I would like to know whether we can create a generic object at
runtime using the type obtained using reflection.

Type myType = Type.GetType("Namespace.Class");
MyClass<myType> test1 = new MyClass<myType>();

Basically, i need to create the generic object at run time and the
type is decided at runtime.

Thanks,
Senthil

Certainly, you need to use Type.MakeGenericType in C# 2.0, this replaces a
..NET 1.0 method that is deprecated and that I can't remember the name of.

{
Type myType = Type.GetType("Namespace.Class");

Type[] typeArgs = new Type[] { myType };

Type typeToCreate = typeof(MyClass<>).MakeGenericType(typeArgs);

MyClass test1 = (MyClass) Activator.CreateInstance(typeToCreate,
typeArgs);
}

Joanna,

MakeGenericType doesn't replace anything in .NET 1.0 because it never
existed in .NET 1.0.

Aaahh ! Brain fart )

I think I meant beta 1 of the .NET 2 framework.
