How do I copy the contents of a String to the clipboard in C#? [duplicate]

Answer 1

This works for me:

You want to do:

System.Windows.Forms.Clipboard.SetText("String to be copied to Clipboard");

But it causes an error saying it must be in a single thread of ApartmentState.STA.

So let's make it run in such a thread. The code for it:

public void somethingToRunInThread()
{
    System.Windows.Forms.Clipboard.SetText("String to be copied to Clipboard");
}

protected void copy_to_clipboard()
{
    Thread clipboardThread = new Thread(somethingToRunInThread);
    clipboardThread.SetApartmentState(ApartmentState.STA);
    clipboardThread.IsBackground = false;
    clipboardThread.Start();
}

After calling copy_to_clipboard(), the string is copied into the clipboard, so you can Paste or Ctrl + V and get back the string as String to be copied to the clipboard.
