string is a C# alias for System.String .
So technically, there is no difference. It's like int vs. System.Int32

As for guidelines, it's generally recommended to use string whenever you refer to an object.

e.g

 string place = "world";

Similarly, I think using String is generally recommended if you need to refer specifically to the class.

e.g

 string greet = String.Format("Hello {0}!", place);

This is the style Microsoft often uses in its examples .

It appears that guidance in this area may have changed, as StyleCop now requires the use of C#-specific aliases.
