Activator.CreateInstance(Of T) Method
Creates an instance of the type designated by the specified generic type parameter, using the parameterless constructor.
Assembly: mscorlib (in mscorlib.dll)
The 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 generic method.
In general, there is no use for the generic method 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++). If the type is not known at compile time, you can call a non-generic overload of CreateInstance.
There are no overloads of the generic method that take argument lists, because the non-generic overloads of CreateInstance already provide late-bound constructor resolution.
