打开族，加载族

[Transaction(TransactionMode.Automatic)]
//类特性,必须在方类前面声明 //调用族文件
public class CommandLoadFamily : IExternalCommand //接口
{

public Result Execute(ExternalCommandData revit, ref string message, ElementSet elements)
{
UIDocument uidoc = revit.Application.ActiveUIDocument;

// uidoc.Document.LoadFamily(@"D:\revit\Revit文件\万能窗.rfa"); //加载族
System.Diagnostics.Process.Start(@"D:\revit\Revit文件\万能窗.rfa "); //打开族

return Result.Succeeded;

}

}

载入，创建，编辑
LoadFamily，CreateIn***，EditFamily...
我想知道你为什么要载入族后打开族。。
