ldtoken token

Converts a metadata token to its runtime representation.

The stack transitional behavior, in sequential order, is:

  1. The passed token is converted to a RuntimeHandle and pushed onto the stack.

The ldtoken instruction pushes a RuntimeHandle for the specified metadata token. A RuntimeHandle can be a fieldref/fielddef, a methodref/methoddef, or a typeref/typedef.

The value pushed on the stack can be used in calls to Reflection methods in the system class library.

For information on runtime handles, see the following classes: RuntimeFieldHandle, RuntimeTypeHandle, and RuntimeMethodHandle.

The following Emit method overloads can use the ldtoken opcode:

  • ILGenerator.Emit(OpCode, MethodInfo)

  • ILGenerator.Emit(OpCode, FieldInfo)

  • ILGenerator.Emit(OpCode, Type)
