br target

Branches to a target instruction at the specified offset.

No evaluation stack behaviors are performed by this operation.

The br instruction unconditionally transfers control to a 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 br opcode:

  • ILGenerator.Emit(OpCode, Label)
