Activator.CreateInstance Generic Method ()

Creates an instance of the type designated by the specified generic type parameter.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

public static T CreateInstance<T> ()
J# supports the use of generic types and methods, but not the declaration of new ones.
JScript does not support generic types and methods.
Not applicable.

Type Parameters

T

The type to create.

Return Value

A reference to the newly created object.

The CreateInstance generic method is used by compilers to implement the instantiation of types specified by type parameters. For example, in the following generic method, the implementation of new T() (gcnew T() in C++) uses the CreateInstance generic method.

public static T Factory<T>() where T:new() 
{
    return new T();   
}

In general, there is no use for the CreateInstance in application code, because the type must be known at compile time. If the type is known at compile time, normal instantiation syntax can be used (new operator in C#, New in Visual Basic, gcnew in C++).

There are no overloads of the CreateInstance generic method that take argument lists, because the non-generic overloads of CreateInstance already provide late-bound constructor resolution.
