Copies the value type located at the address of an object (type &, * or natural int) to the address of the destination object (type &, * or natural int).
[Visual Basic] Public Shared ReadOnly Cpobj As OpCode [C#] public static readonly OpCode Cpobj; [C++] public: static OpCode Cpobj; [JScript] public static var Cpobj : OpCode;
The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:
|70 < T >||cpobj classTok||Copies a value type from a source object to a destination object.|
The stack transitional behavior, in sequential order, is:
- The destination object reference is pushed onto the stack.
- The source object reference is pushed onto the stack.
- The two object references are popped from the stack; the value type at the address of the source object is copied to the address of the destination object.
The behavior of cpobj is unspecified if the source and destination object references are not pointers to instances of the class represented by the class token classTok (a typeref or typedef), or if classTok does not represent a value type.
NullReferenceException may be thrown if an invalid address is detected.
The following Emit constructor overload can use the cpobj opcode:
- ILGenerator.Emit(OpCode, Type)
