The data to place on the Clipboard.


true if you want data to remain on the Clipboard after this application exits; otherwise, false.


The number of times to attempt placing the data on the Clipboard.


The number of milliseconds to pause between attempts.

Exception typeCondition


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


data is a null reference (Nothing in Visual Basic).


retryTimes is less than zero.


retryDelay is less than zero.


Data could not be placed on the Clipboard. This typically occurs when the Clipboard is being used by another process.

Adding data to the Clipboard can occasionally fail if the Clipboard is busy with another thread or application. This method is useful to work around this issue in environments with heavy Clipboard use.

If the copy parameter is false, the data will be deleted from system Clipboard when the application exits.


An object must be serializable for it to be put on the Clipboard. If you pass a non-serializable object to this method, it will fail without throwing an exception. See Serialization for more information on serialization.

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.
