If the Tag of a FlowChartObject is String, It is OK.
ex:
box.tag = "abc";
flowChart.CopyToClipboard(true);
then
flowChart.PasteFromClipboard(...);
the new box's tag is still "abc";

but if the box tag is a Object, the new pasted box 's tag is null.
ex:

Lable label = new Label;
label .Text = "label1";
box.tag = label ;
flowChart.CopyToClipboard(true);
then
flowChart.PasteFromClipboard(...);
the new box's tag is null;

why?
the flowchart version is  4.2.1

The Tag object must be serializable if you want it to be saved in diagram files, copied to / pasted from the clipboard, etc. If the Label class is defined in your application, add a [Serializable] attribute just above the class declaration.

Another question is:
box1's MasterGroup is group1.
then
flowChart.CopyToClipboard(true,true);
then
flowChart.PasteFromClipboard(x,y);
why the MasterGroup of new box is null?

The second bool parameter specifies if the subordinate items of a selected master item should be copied.

If only a subordinate item is selected, its master item and group won't be copied. You will have to programmatically add the master tem to the selection if you won't the group to be copied too.
