body: <p>I am trying to capture input data from a Textbox by converting it to <code>DateTime</code> format</p>
  
  <pre><code>string yy = string.Format("{0:T}", textBox1.Text);
  </code></pre>
  
  <p>I wish to use <code>Try-Catch-Finally</code> to produce an <code>Systm.FormatException</code> error and display it  in another text box</p>
  
  <pre><code>try 
  {
   DateTime XF = Convert.ToDateTime(yy); 
  }
   catch (FormatException)    
         { 
         textBox5.Text = "incorrect time"; 
         }
     finally 
            {
             DateTime XF = Convert.ToDateTime(yy); 
             textBox5.Text = Convert.ToString(XF.Hour + XF.Minute + XF.Second); 
            }
  </code></pre>
  
  <p>How should i go around?</p>
  
  <p>Thanks</p>
