Loads the element with type float32 at a specified array index onto the top of the evaluation stack as type F (float).
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 type float32 at index onto the top of the stack as a type F.
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.r4 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.r4 is float32.
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.r4 opcode:
