How to check stringbuilder is empty

Question

Rajanikant Hawaldar · Answer

StringBuilder sb = new StringBuilder(); if (sb.Length != 0) { // you have found some difference }

Dipa Mehta · Answer

You can use the Length property: Gets or sets the length of the current StringBuilder object. StringBuilder sb = new StringBuilder(); if (sb.Length != 0) { // you have found some difference } Another possibility would be to treat it as a string by using the String.IsNullOrEmpty method and condense the builder to a string using the ToString method. You can even grab the resulting string and assign it to a variable which you would use if you have found some differences: string difference = "" ; if (!String.IsNullOrEmpty(difference = sb.ToString())) { Console.WriteLine(difference); }

hi private static void checkstringbuilderclass() { StringBuilder sb = new StringBuilder(); if (String.IsNullOrEmpty(sb.ToString())) Console.WriteLine( "Convert to string and call IsNullOrEmpty method" ); if (sb.ToString() == "" ) Console.WriteLine( "Convert to string and check Null variable" ); if (sb.Length == 0) Console.WriteLine( "check length" ); }
