Remarks

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
90	ldelem.i1	Loads the element with type int8 at index onto the top of the stack as an int32.

The stack transitional behavior, in sequential order, is:

1. An object reference array is pushed onto the stack.

2. An index value index is pushed onto the stack.

3. index and array are popped from the stack; the value stored at position index in array is looked up.

4. The value is pushed onto the stack.

The ldelem.i1 instruction loads the value of the element with index index (type native int) in the zero-based one-dimensional array array and places it on the top of the stack. Arrays are objects and hence represented by a value of type O.

The return value for ldelem.i1 is int8.

Note that integer values of less than 4 bytes are extended to int32 (not native int) when they are loaded onto the evaluation stack.

NullReferenceException is thrown if array is a null reference.

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

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

The following Emit method overload can use the ldelem.i1 opcode:

• ILGenerator.Emit(OpCode)
