Activator.CreateInstance(Of T) Method
July 28, 2014
Creates an instance of the type designated by the specified generic type parameter, using the parameterless constructor.
Assembly: mscorlib (in mscorlib.dll)
The type that is specified for T does not have a parameterless constructor.
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 method overload in application code, because the type must be known at compile time. If the type is known at compile time, standard instantiation syntax can be used (new operator in C#, New in Visual Basic, gcnew in C++).
There are no generic overloads of the CreateInstance method that take argument lists, because the non-generic overloads already provide late-bound constructor resolution.
