title: Copy and paste with C#
body: <p>I know this is asked many times before but it s not what i look for, to make copy paste in c# we use;</p>
  
  <pre><code>//Copy
  Clipboard.SetDataObject("String to copy"); 
  
  //Paste
  IDataObject iData = Clipboard.GetDataObject(); 
  </code></pre>
  
  <p>I only want to use copy, after using:</p>
  
  <pre><code>Clipboard.SetDataObject("String to copy"); 
  </code></pre>
  
  <p>when i close the program, then when i right click and paste on a txt file nothing happens!
  <br>
  So Clipboard class seems doesnt help, so i need another solution.</p>
