What is the difference between String and string

I’m using string for a variable, like this

string myString = "test";

And I’m using String if I want to use some methods(?) of the Class String

String.Format...

I thought this is looking better. Buy some people are doing stuff like

String myString;
string.Format...

Its working. But I don’t like this. How can I tell them to stop? Is there “C# rule” for stuff like this? The same thing for int,Int; char,Char; …

Answer 1

string is a C# alias to System.String.

If writing C#, you should be using the alias, so string.Format and string myString.

Both end up compiled to the same IL and mean the same thing, but C# has its idioms and using the type alias is part of them – in the same way that you would use int and not System.Int32.
