Examples

The following example demonstrates the use of this method.


               // For this example, the data to be placed on the clipboard is a simple
               // string.
               string textData = "I want to put this string on the clipboard.";
               // The example will enable auto-conversion of data for this data object.
               bool autoConvert = true;

               // Create a new data object, specifying the data format, data to encapsulate, and enabling
               // auto-conversion services.
               DataObject data = new DataObject(DataFormats.UnicodeText, (Object)textData, autoConvert);
               
               // If the data to be copied is supposed to be persisted after the application ends, 
               // then set the second parameter of SetDataObject to true.
               if(persistentData)
               {
                   // Place the persisted data on the clipboard.
                   Clipboard.SetDataObject(data, true);
               }
               else
               {
                   // Place the non-persisted data on the clipboard.
                   Clipboard.SetDataObject(data, false);
               }

               // If you keep a copy of the source data object, you can use the IsCurrent method to see if
               // the data object is still on the clipboard.
               bool isOriginalDataObject = Clipboard.IsCurrent(data);

Remarks

Use this method to determine if a data object that was previously placed on the Clipboard is still present and unmodified.
