This is the second in a series of quick how-to posts on ReSharper.
Tip #2 – Create Field
Use: Within the body of a class or property, you can type the name of a non-existent variable name. When you place your cursor on the variable, ReSharper provides several options to resolve the impending compilation error. Create Field is one of the options.
Before
1: public void AddAlbum(string album)
2: {
3: if (String.IsNullOrWhiteSpace(album))
4: throw new ArgumentOutOfRangeException("album",
5: album,
6: "Please provide an album name.");
7:
8: _albums.Add(album);
9: }
Press <Alt+Enter>
After
private IList<string> _albums = new List<string>(); public void AddAlbum(string album) { if (String.IsNullOrWhiteSpace(album)) throw new ArgumentOutOfRangeException("album", album, "Please provide an album name."); _albums.Add(album); }
Note: I chose the type IList<string>. The default type selected by ReSharper in this case was object. I also added the initializer to the field to avoid null reference exceptions. Please don’t take any of these examples as best coding practices, they are contrived to demonstrate a particular refactoring.
Happy coding!
