Replaces the value stored in the field of an object reference or pointer with a new value.
[Visual Basic] Public Shared ReadOnly Stfld As OpCode [C#] public static readonly OpCode Stfld; [C++] public: static OpCode Stfld; [JScript] public static var Stfld : OpCode;
The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:
|7D < T >||stfld field||Replaces the value of field of the object with a new value.|
The stack transitional behavior, in sequential order, is:
- An object reference or pointer is pushed onto the stack.
- A value is pushed onto the stack.
- The value and the object reference/pointer are popped from the stack; the value of field in the object is replaced with the supplied value.
The stfld instruction replaces the value of a field of an object (type O) or via a pointer (type natural int, &, or *) with a givne value. Field is a metadata token that refers to a field member reference. The stfld instruction can have a prefix of either or both of Unaligned and Volatile.
NullReferenceException is thrown if the object reference or pointer is a null reference and the field isn't static.
MissingFieldException is thrown if field is not found in the metadata. This is typically checked when the Microsoft Intermediate Language (MSIL) instruction is converted to native code, not at runtime.
The following Emit constructor overload can use the stfld opcode:
- ILGenerator.Emit(OpCode, FieldInfo)
