Public Shared ReadOnly Ldelem As OpCode
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 |
---|---|---|
A3 < T > |
ldelem typeTok |
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
andarray
are popped from the stack; the value stored at positionindex
inarray
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:
