void

When used as the return type for a method, void specifies that the method does not return a value.

void is not allowed in a method's parameter list. A method that takes no parameters and returns no value is declared as follows:

void MyMethod();

void is also used in an unsafe context to declare a pointer to an unknown type. For more information, see A.2 Pointer types.
