OpCodes.Ceq Field

Compares two values. If they are equal, the integer value 1 (int32) is pushed onto the evaluation stack; otherwise 0 (int32) is pushed onto the evaluation stack.

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 01 ceq Pushes 1 if value1 equals value2; else pushes 0.

The stack transitional behavior, in sequential order, is:

  1. value1 is pushed onto the stack.
  2. value2 is pushed onto the stack.
  3. value2 and value1 are popped from the stack; value1 is added to value2.
  4. The result is pushed onto the stack.

The ceq instruction compares value1 and value2. If value1 is equal to value2, then 1 (of type int32) is pushed on the stack. Otherwise 0 (of type int32) is pushed on the stack.

For floating-point number, ceq will return 0 if the numbers are unordered (either or both are NaN). The infinite values are equal to themselves.

The following Emit constructor overload can use the ceq opcode:

  • ILGenerator.Emit(OpCode)
