ReSharper Wish List: Replace Literal With…

Posted August 8, 2008 * Comments(4)

One thing I would love ReSharper to do for me is to replace a literal string with a local variable or constant and also refactor any other usings, optionally including internal usages, of the same string literal.

I would like for it to take:

public string Foo(IDictionary<string,string> d){
     if(d.ContainsKey("foo")){
         return d["foo"];
     }
     return string.Empty;
}

…and change it to:

public string Foo(IDictionary<string,string> d){
     string key = "foo";
     if(d.ContainsKey(key)){
         return d[key];
     }
     return string.Empty;
}

That sounds very doable to me, but maybe I’m not seeing the complexity. I know ReSharper has API’s for creating your own custom context actions, but I haven’t looked into that yet.

    We already have this functionality. You should select “Foo” and use “Introduce Variable” refactoring. It will do the rest :)

    That’s great! It isn’t as discoverable as a context action, but pretty easy.

    Ctrl+R,F = Introduce Field
    Ctrl+R,V = Introduce Variable

    Be sure to Ctrl+w with the cursor in the string to extend the selection to the entire string.

    I added this as ReSharper Tip of the Day: Introduce Variable.
