I recently came across this problem, and was using a custom format in the clipboard, making Interop a bit more difficult. Anyway, with a bit of light reflection I was able to get to the original System.Windows.Forms.DataObject, and then call the GetData and get my custom item out of it like normal.

var oleConverterType = Type.GetType("System.Windows.DataObject+OleConverter, PresentationCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35");
var oleConverter = typeof(System.Windows.DataObject).GetField("_innerData", BindingFlags.NonPublic | BindingFlags.Instance).GetValue(e.Data);
var dataObject = (System.Windows.Forms.DataObject)oleConverterType.GetProperty("OleDataObject").GetValue(oleConverter, null);

var item = dataObject.GetData(this.Format);
