.NET Windows Forms in a Nutshell

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 ); }
