That should look like this: TimeSpan tsStart; TimeSpan tsEnd; //tsStart you get parsing from masked textBox tsStart= TimeSpan.Parse(maskedTextBox1.Text); //tsEnd is time what you choose tsEnd = new TimeSpan(20 50 30); //Then using usual if statement you can check is tsStart smaller or bigger than tsEnd if (tsStart { } If something isn't clear just say.
