Loads the element containing an object reference at a specified array index onto the top of the evaluation stack as type O (object reference).
Assembly: mscorlib (in mscorlib.dll)
The following table lists the instruction's hexadecimal and Microsoft intermediate language (MSIL) assembly format, along with a brief reference summary:
Loads the element with an object reference at index onto the top of the stack as type O.
The stack transitional behavior, in sequential order, is:
An object reference array is pushed onto the stack.
An index value index is pushed onto the stack.
index and array are popped from the stack; the value stored at position index in array is looked up.
The value is pushed onto the stack.
The ldelem.ref 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.ref is type O (object reference).
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.ref opcode:
