Codes. Stelem_Ref Field
Replaces the array element at a given index with the object ref value (type
O) on the evaluation stack.

The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:

The stack transitional behavior, in sequential order, is:
An object reference to an array,
array, is pushed onto the stack.
A valid index to an element in
arrayis pushed onto the stack.
A value is pushed onto the stack.
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.
stelem.ref instruction replaces the value of the element at the supplied index in the one-dimensional array
array with the
O) value pushed onto the stack.
Arrays are objects and hence represented by a value of type
O. The index is type
stelem.ref implicitly casts the supplied value to the element type of
array before assigning the value to the array element. This cast can fail, even for verified code. Thus the
stelem.ref instruction can throw InvalidCastException. For one-dimensional arrays that aren't zero-based and for multidimensional arrays, the Array class provides a SetValue method.
NullReferenceException is thrown if
array is a null reference.
IndexOutOfRangeException is thrown if
index is negative, or larger than the bound of
ArrayTypeMismatchException is thrown if
array does not hold elements of the required type.
The following Emit method overload can use the
