Creating T From Type

[sternr]

Hey,
I have the following class:

public Child<T>
{
//Some Code
}

Can I (using Reflection or any other way) create a Child object in
runtime without knowing what is T? like this:
static object GetChild(Type t)
{

}

Thanks ahead

I think you'll have to use
static object GetChild<T>() : where T : new()

Hello sternr,

public class Tests {

public void Test( ) {
Assert.AreEqual(typeof(MyClass<string>),
CreateTypeForType(typeof(string)).GetType());
}

private object CreateTypeForType(Type genericParameter) {
Type openType = typeof(MyClass<>);
Type finalType = openType.MakeGenericType(genericParameter);
return Activator.CreateInstance(finalType);
}
}

public class MyClass<T> {
}
