Field Value


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
9B stelem.i Replaces an array element at the supplied index with the native int value on the stack.

The stack transitional behavior, in sequential order, is:

  1. An object reference to an array, array, is pushed onto the stack.

  2. A valid index to an element in array is pushed onto the stack.

  3. A value is pushed onto the stack.

  4. The value, the index, and the array reference are popped from the stack; the value is put into the array element at the given index.

The stelem.i instruction replaces the value of the element index in the one-dimensional array array with the native int value pushed onto the stack.

Arrays are objects and hence represented by a value of type O. The index is type native int.

NullReferenceException is thrown if array is a null reference.

IndexOutOfRangeException is thrown if index is negative, or larger than the bound of array.

ArrayTypeMismatchException is thrown if array does not hold elements of the required type.

The following Emit method overload can use the stelem.i opcode:

  • ILGenerator.Emit(OpCode)
