Shortcut for creating single item list in C#

Simply use this:

List<string> list = new List<string>() { "single value" };

You can even omit the () braces:

List<string> list = new List<string> { "single value" };

Update: of course this also works for more than one entry:

List<string> list = new List<string> { "value1", "value2", ... };
