What is the difference between String.Empty and “” (empty string)?

Question

In .NET, what is the difference between String.Empty and \"\", and are they interchangable, or is there some underlying reference or Localization i

Answer 1

Everybody here gave some good theoretical clarification. I had a similar doubt. So I tried a basic coding on it. And I found a difference. Here's the difference.

string str=null;
Console.WriteLine(str.Length);  // Exception(NullRefernceException) for pointing to null reference. 


string str = string.Empty;
Console.WriteLine(str.Length);  // 0

So it seems "Null" means absolutely void & "String.Empty" means It contains some kind of value, but it is empty.
