ldvirtftn method |
Pushes the pointer to an object's virtual method method on the stack. |
The stack transitional behavior, in sequential order, is:
An object reference is pushed onto the stack.
The object reference is popped from the stack and the address of the entry point to the method (as specified by the metadata token method) is looked up.
The pointer to method is pushed onto the stack.
The resulting unmanaged pointer pushed onto the stack by the ldvirtftn instruction can be called using the Calli instruction if it references a managed method (or a stub that transitions from managed to unmanaged code).
The unmanaged pointer points to native code using the calling convention specified by in the metadata token method. As a result, the method pointer can be passed to unmanaged native code (for example, as a callback routine) if that routine expects the corresponding calling convention.
The following Emit method overload can use the ldvirtftn opcode:
- ILGenerator.Emit(OpCode, MethodInfo)
