class

This class provides a basic implementation of the IDataObject interface that supports data transfer in Clipboard and drag-and-drop scenarios.

You can add the data you wish to encapsulate in one or more different formats using the SetData() method. There are three overloads that allow you to add the data either specifying a string indicating the format (perhaps from the DataFormats class), using a Type name as the format ID, or with no extra information, which defaults to using the class name as the ID.

When you are on the receiving end of one of these objects, you can use the GetData() method to retrieve the data for a particular format ID, perhaps using the GetDataPresent() method to determine whether there is any data stored in a particular format. You can also call GetFormats() to get a list of all the formats for which data is stored in the object.
