I don't know why the method GetData() requires a parameter of Type, I thought the Type is to specify that of which class/type the object should be.
I have a structure called GraphicsPathWrap, it's made serializable by implementing ISerializable. I tried the following copy function:
 
private void Copy(GraphicsPathWrap gpw){
  DataObject obj = new DataObject();
  obj.SetData(typeof(GraphicsPathWrap), gpw);
  Clipboard.SetDataObject(obj);
}
 
Then tried the following paste function:
private GraphicsPathWrap Paste()
{
  return (GraphicsPathWrap)Clipboard.GetDataObject().GetData(typeof(GraphicsPathWrap));
}
 
It should work, but the GetData(...) returns an object of type MemoryStream and an InvalidCastException was thrown. I don't understand why it's type of MemoryStream. I thought it should be able to be casted to GraphicsPathWrap?
I can work around this by using a BinaryFormatter to deserialize the MemoryStream but it's too ridiculous when Clipboard can't do all the thing for me?
 
Thanks!
