Transfers control to a target instruction when two unsigned integer values or unordered float values are not equal.
Assembly: mscorlib (in mscorlib.dll)
The following table lists the instruction's hexadecimal and Microsoft Intermediate Language (MSIL) assembly format, along with a brief reference summary:
40 < int32 >
Branch to the target instruction at the specified offset if two unsigned integer values are not equal (unsigned values).
The stack transitional behavior, in sequential order, is:
value1 is pushed onto the stack.
value2 is pushed onto the stack.
value2 and value1 are popped from the stack; if value1 is not equal to value2, the branch operation is performed.
The bne.un instruction transfers control to the specified target instruction if value1 is not equal to value2, when compared using unsigned integer or unordered float values. The effect is identical to performing a ceq.un instruction followed by a brfalse branch to the specific target instruction. The target instruction is represented as a 4-byte signed offset from the beginning of the instruction following the current instruction.
Control can only be transferred to the first of these prefixes if the target instruction has one or more prefix codes. Control transfers into and out of try, catch, filter, and finally blocks cannot be performed by this instruction.
The following Emit method overload can use the bne.un opcode:
Windows 7, Windows Vista SP1 or later, Windows XP SP3, Windows XP SP2 x64 Edition, Windows Server 2008 (Server Core not supported), Windows Server 2008 R2 (Server Core supported with SP1 or later), Windows Server 2003 SP2
