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 OB < unsigned int16 > starg num Pops the top value from the stack and stores it in argument slot num.

The stack transitional behavior, in sequential order, is:

  1. The value currently on top of the stack is popped and placed in argument slot num.

The starg instruction pops a value from the stack and places it in argument slot num. The type of the value must match the type of the argument, as specified in the current method's signature.

For procedures that take a variable argument list, the starg instruction can be used only for the initial fixed arguments, not those in the variable part of the signature.

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

The following Emit constructor overload can use the starg opcode:

  • ILGenerator.Emit(OpCode, short)
