如题，苦于无门，求高手赐教，开发语言为C#，如有Vb的也可，有Demo更好！万分感谢！

TypedValue[] filList = new TypedValue[1] {new TypedValue((int)DxfCode.Start, "INSERT")};
SelectionFilter filter =new SelectionFilter(filList);
PromptSelectionOptions opts =new PromptSelectionOptions();
opts.MessageForAdding = "Select block references: ";
PromptSelectionResult res = ed.GetSelection(opts, filter);

请问能否指教下这段代码的含义？
