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 |
|---|---|---|
| 99 | ldelem.r8 | Loads the element with type float64 at index onto the top of the stack as type F. |
The stack transitional behavior, in sequential order, is:
An object reference
arrayis pushed onto the stack.An index value
indexis pushed onto the stack.indexandarrayare popped from the stack; the value stored at positionindexinarrayis looked up.The value is pushed onto the stack.
The ldelem.r8 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.r8 is float64.
Floating-point values are converted to type F when 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.r8 opcode:
