revit api获取工作集的名称

从这个参数里的AsValueString（） 函数可以直接获得工作集的名称， Parameter.AsValueString()

		public void GetworkSetName()
		{
			
			Document doc = this.ActiveUIDocument.Document;
			Selection sel = this.ActiveUIDocument.Selection;
			
			Reference ref1 = sel.PickObject(ObjectType.Element,"Please pick an element to get the work set name");	
			Element elem = doc.GetElement(ref1);
			
			int worksetvalue = elem.get_Parameter(BuiltInParameter.ELEM_PARTITION_PARAM).AsInteger();
			
			WorksetId id = new WorksetId(worksetvalue);
			
			WorksetTable table = doc.GetWorksetTable();
			Workset ws = table.GetWorkset(id);
			TaskDialog.Show("get elemetn's work set name",ws.Name);
			
		}
