Remarks
The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:

ldobj class |
Copy instance of value type class to the stack. |
The stack transitional behavior, in sequential order, is:
The address of a value type object is pushed onto the stack.
The address is popped from the stack and the instance at that particular address is looked up.
The value of the object stored at that address is pushed onto the stack.
The ldobj instruction is used to pass a value type as a parameter.
The ldobj instruction copies the value pointed to by addrOfValObj (of type &, *, or native int) to the top of the stack. The number of bytes copied depends on the size of the class (as specified by the class parameter). The class parameter is a metadata token representing the value type.
The operation of the ldobj instruction can be altered by an immediately preceding Volatile or Unaligned prefix instruction.
TypeLoadException is thrown if class cannot be found. This is typically detected when the Microsoft Intermediate Language (MSIL) instruction is converted to native code rather than at runtime.
The following Emit method overload can use the ldobj opcode:
