Hi all i think its not big deal to convert string value to bool just check string value is null or not and then convert. simple

Somehow I fail to understand why we need Convert.ToBoolean at all? Is following not good enough? public String Test; Boolean Test1 = String.IsNullOrEmpty(Test) ? false : (Test == 1 ? true : false);
