Use String.Concat instead of '+' operator when you combine 2 string. this will better performance

In c# Applications in various scenario's programmer's using '+' operator for concatinating strings. its not best practice in the programming. Avoid using '+' operator instead of that always use string.concat() method. If its large string use string builder.

Sample Code :

 DataRow [] dr = dt.select("EmployeeId=" ' " + txtEmployeeId.Text + " ' ");


Replacement Code :


 DataRow [] dr = dt.select(string.concat("EmployeeId=" , txtEmployeeId.Text ));


Thanks ,

Happy Coding!
