.NET Windows Forms in a Nutshell

Name

IDataObject

Synopsis

This interface is used by Clipboard and drag-and-drop operations to encapsulate the data that is being moved around. See DataObject for a description of a typical implementation.

You could provide more complex IDataObject implementations than the simple in-memory version offered by DataObject, perhaps using persistent storage for robustness, but DataObject will do fine for most applications.

public interface IDataObject {

// Public Instance Methods

   public object GetData(string format);

   public object GetData(string format, bool autoConvert);

   public object GetData(Type format);

   public bool GetDataPresent(string format);

   public bool GetDataPresent(string format, bool autoConvert);

   public bool GetDataPresent(Type format);

   public string[ ] GetFormats();

   public string[ ] GetFormats(bool autoConvert);

   public void SetData(object data);

   public void SetData(string format, bool autoConvert, object data);

   public void SetData(string format, object data);

   public void SetData(Type format, object data);

}
