The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:

C6 < T >	mkrefany class	Pushes a typed reference of type class onto the stack.

The stack transitional behavior, in sequential order, is:

[The 'ordered' type of list has not been implemented in the ECMA stylesheet.]

The mkrefany instruction supports the passing of dynamically typed references. The pointer must be of type &, *, or native int, and hold the valid address of a piece of data. Class is the class token describing the type of the data referenced by the pointer. Mkrefany pushes a typed reference on the stack, providing an opaque descriptor of the pointer and the type class.

The only valid operation permitted upon a typed reference is to pass it to a method that requires a typed reference as a parameter. The callee can then use the OpCodes.Refanytype and OpCodes.Refanyval instructions to retrieve the type (class) and the address respectively.

TypeLoadException is thrown if class cannot be found. This is typically detected when Microsoft Intermediate Language (MSIL) instructions are converted to native code rather than at runtime.

The following ILGenerator.Emit(OpCode) method overload can use the mkrefany opcode:
