Loads the element at a specified array index onto the top of the evaluation stack as the type specified in the instruction.
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:
A3 < T >
Loads the element at index onto the top of the stack as type typeTok.
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 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 type of the return value is specified by the token typeTok in the instruction.
NullReferenceException is thrown if array is a null reference.
IndexOutOfRangeException is thrown if index is negative, or larger than the upper bound of array.
The following Emit method overload can use the ldelem opcode:
Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows XP SP2 x64 Edition, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
