Clipboard.ContainsText Method ()

Indicates whether there is data on the Clipboard in the Text or UnicodeText format, depending on the operating system.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public static bool ContainsText ()
public static boolean ContainsText ()
public static function ContainsText () : boolean
Not applicable.

Return Value

true if there is text data on the Clipboard; otherwise, false.

Exception typeCondition

ExternalException

The Clipboard could not be cleared. This typically occurs when the Clipboard is being used by another process.

ThreadStateException

The current thread is not in single-threaded apartment (STA) mode. Add the STAThreadAttribute to your application's Main method.

This method checks for the presence of data in the UnicodeText format on Windows XP Home Edition, Windows XP Professional, Windows Server 2003 and Windows 2000. Otherwise, this method checks for the presence of data in the Text format.

Use this method to determine whether the Clipboard contains text data before retrieving it with the GetText method.

NoteNote:

The Clipboard class can only be used in threads set to single thread apartment (STA) mode. To use this class, ensure that your Main method is marked with the STAThreadAttribute attribute.

The following example demonstrates an overload of the ContainsText method that is similar to this overload.

// Demonstrates SetText, ContainsText, and GetText.
public String SwapClipboardHtmlText(String replacementHtmlText)
{
    String returnHtmlText = null;
    if (Clipboard.ContainsText(TextDataFormat.Html))
    {
        returnHtmlText = Clipboard.GetText(TextDataFormat.Html);
        Clipboard.SetText(replacementHtmlText, TextDataFormat.Html);
    }
    return returnHtmlText;
}
