Hi Rashmi, You can call variables and methods from class 1 by .(DOT) Operator directly without creating Instance of Class 1 as It is Static.

Hi check the solution. dont create instance of a static class. function in an static class can be accessed directly without creating instance. namespace s1 { publis static class class1 { public static string a="IN"; public static string b="DIA"; public static void stringconcat(a,b); } } In File2.cs ---------------- namespace s1 { publis static class class2 { class1.stringconcat(a,b); } }

Hi You are try to create an instance of static class. But it is not possible to create instance of static class. Solution 1) Create your class and variable as non static Solution 2) Call you method with the name of class (without creating an instance).
