stobj class

Stores a value of type class from the stack into memory.

The stack transitional behavior, in sequential order, is:

  1. An address is pushed onto the stack.

  2. A value type object of type class is pushed onto the stack.

  3. The object and the address are popped from the stack; the value type object is stored at the address.

The stobj instruction copies the value type object into the address specified by the address (a pointer of type native int, *, or &). The number of bytes copied depends on the size of the class represented by class, a metadata token representing a value type.

The operation of the stobj 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 MSIL instructions are converted to native code, not at run time.

The following Emit method overload can use the stobj opcode:

  • ILGenerator.Emit(OpCode, Type)
