IS Operator: The is operator is used to check whether the run-time type of an object is compatible with a given type or not. Example: object num=10; if (num is int) { Response.Write("Num is integer"); } AS Operator: The as operator is used to perform conversions between compatible types. Example: object obj = "This is string"; string str = string.Empty; if (obj is string) { str = obj as string; Response.Write(str); }
