call the current method, using some sort of keyword? for self reference

Hi

Is there anyway i can call the current method from inside without typing the method name again (incase the method name is changed by someone else later)

So currently, i call the same name internally (SelfRef), this will cause a bug in future maintenance if not using a code auditing program

i.e.

 void SelfRef(string _Input){
         
         if (_Input == "route1"){
             
             //route1 calls route 2
             
             SelfRef("route2"); //call self
             
             
         }else if (_Input == "route2"){
             
             //route2 ends
         }
     }
