ldloca.s index

Loads the address of the local variable at index onto the evaluation stack, short form.

The stack transitional behavior, in sequential order, is:

  1. The address stored in the local variable at the specified index is pushed onto the stack.

The ldloca.s instruction pushes the address of the local variable number at the passed index onto the stack, where local variables are numbered 0 onwards. The value pushed on the stack is already aligned correctly for use with instructions like Ldind_I and Stind_I. The result is a transient pointer (type *).

The ldloca.s instruction provides an efficient encoding for use with the local variables 0 through 255.

The following Emit method overload can use the ldloca.s opcode:

  • ILGenerator.Emit(OpCode, byte)
