stloc index

Pops a value from the stack and stores it in local variable index.

The stack transitional behavior, in sequential order, is:

  1. A value is popped off of the stack and placed in local variable index.

The stloc instruction pops the top value off the evaluation stack and moves it into local variable number index, where local variables are numbered 0 onwards. The type of the value must match the type of the local variable as specified in the current method's local signature.

Storing into locals that hold an integer value smaller than 4 bytes long truncates the value as it moves from the stack to the local variable. Floating-point values are rounded from their native size (type F) to the size associated with the argument.

Correct MSIL instructions require that index be a valid local index. For the stloc instruction, index must lie in the range 0 to 65534 inclusive (specifically, 65535 is not valid). The reason for excluding 65535 is pragmatic: likely implementations will use a 2-byte integer to track both a local's index, as well as the total number of locals for a given method. If an index of 65535 had been made valid, it would require a wider integer to track the number of locals in such a method.

The following Emit method overloads can use the stloc opcode:

  • ILGenerator.Emit(OpCode, LocalBuilder)

  • ILGenerator.Emit(OpCode, short)
