As we know we can't used the reserved word, but if you really want used, let's with me.
 
I have used console application. I make one method and this method Name is @String. if we are directly used string 
- public void @string()      
-       {      
-         Console.WriteLine("String is a reserved word");      
-       }      
 
 Call here above method.
- static void Main(string[] args)    
- {    
-     Program p = new Program();    
-     p.@string();    
-     
- }    
 
Note:- When we are used the Reserved keyword then must be prefix '@' on the Reserved word. 
 
Make another method and name is @name. 
- public void @Name()  
-         {  
-   
-                       Console.WriteLine("@name Not a reserved keyword ");  
-         }  
 
 Call here above method
- static void Main(string[] args)      
- {      
-     Program p = new Program();      
-     p.Name();      
-       
- }      
 
 I hope it's very useful for who's want set the Reserved name set on the Method name.
