Pushes an unmanaged pointer (type
natural int) to the native code implementing a specific method onto the evaluation stack.
Namespace: System.Reflection.Emit
Assembly: mscorlib (in mscorlib.dll)
Syntax
Visual Basic (Declaration)
Public Shared ReadOnly Ldftn As OpCode
Dim value As OpCode
value = OpCodes.Ldftn
public static readonly OpCode Ldftn
public:
static initonly OpCode Ldftn
public static final OpCode Ldftn
public static final var Ldftn : OpCode
Remarks
The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:
| Format | Assembly Format | Description |
| FE 06 < T > | ldftn method | Pushes a pointer to a method referenced by method on the stack. |
The stack transitional behavior, in sequential order, is:
-
The unmanaged pointer to a specific method is pushed onto the stack.
The specific method (method) can be called using the Calli instruction if it references a managed method (or a stub that transitions from managed to unmanaged code).
The value returned points to native code using the calling convention specified by the method metadata token. Thus, a method pointer can be easily passed to unmanaged native code (specifically, as a callback routine).
The following Emit method overload can use the ldftn opcode:
