difference between string.empty and string= c#

Question

Vulpes · Answer

String.Empty is a static readonly field of the System.String class. When the String class is first accessed its static constructor sets its Empty field equal to the string literal . So Sivaraman is correct that they both represent an empty string i.e. a string which contains no characters not even '\0' and so has a Length of zero. However they are treated differently by the compiler in that  is a constant but String.Empty is not. You can see this by trying to compile the following program: using System; class Test { static void Main() { const string s1 = ; const string s2 = String.Empty; } } The error message is : error CS0133: The expression being assigned to 's2' must be constant Notice also that strings are always followed in memory by a null character ('\0') even though this null character is not part of the string itself. This enables you to iterate through the characters of a string using a pointer in 'unsafe' code though there can be problems if the string itself contains embedded nulls.

In .Net Pre 2.0  creates an object while string.empty creates no object .So it is more efficient to use string.Empty String.Empty is not a Constant .Its a Static readonly Field .If it was a constant there would be no diffence between  and string.empty

hi string.empty not holds any thing...string= is having one undisplayed charecter 'space' \0. string.empty is best way...its reduce memory and garbage.

Both are same. Write a simple two statements yourself one with .empty and one with = . Then put a break point in the first statement. Call for Dis-assembly and you will not see any difference. That's why they both are same. You can choose whatever is more readable to you
