Hi, so this is my code:

if (Clipboard.ContainsData(textBox2.Text))
                {
                    System.Diagnostics.Process.Start(@"notepad.exe");
        }

If the clipboard contains the data of textbox 2 then I want my application to open notepad. But every time I use "(Clipboard.ContainsData())" I get an error. Why? My program is not willing to see if the clipboard has the text of textbox 2..

What I have tried:

What's the error?

If you get an error you should post the error message. Since we can't see your computer all details are necessary if you want help diagnosing. Is it possible textbox2.text is null so you can an object reference error or something?

Clipboard.ContainsData does not check for "that data", it checks for a format: Clipboard.ContainsData(String) Method (System.Windows.Forms) | Microsoft Docs[^]
You would need to check for a type of data, and if your textbox doesn't contain a "real" format name, it probably throws an exception.
