This is one of the basic things you need to learn not just only in c# but in every programming language you are going to study.

This is a sample program in c# that demonstrate how to use and functions of an if else statement.

Open the project solution (.sln) in visual studio 2010 or open directly the (.csproj)

                textBox1.Focus();                     
            }
