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
FE 15 < T >	initobj typeTok	Initializes a value type.

The stack transitional behavior, in sequential order, is:

1. The address of the value type to initialize is pushed onto the stack.

2. The address is popped from the stack; the value type at the specified address is initialized as type typeTok.

The initobj instruction initializes each field of the value type specified by the pushed address (of type native int, &, or *) to a null reference or a 0 of the appropriate primitive type. After this method is called, the instance is ready for a constructor method to be called. If typeTok is a reference type, this instruction has the same effect as ldnull followed by stind.ref.

Unlike Newobj, initobj does not call the constructor method. Initobj is intended for initializing value types, while newobj is used to allocate and initialize objects.

The following Emit method overload can use the initobj opcode:

• ILGenerator.Emit(OpCode, Type)
