Revit API获取链接模型状态

FilteredElementCollector links = new FilteredElementCollector(doc)
    .OfCategory(BuiltInCategory.OST_RvtLinks)
    .WhereElementIsNotElementType();
foreach (Element e in links)
{
    if (e is RevitLinkType link)
    {
        var isLoaded = RevitLinkType.IsLoaded(doc, e.Id);
        ExternalFileReference EX = e.GetExternalFileReference();
        var filePath = EX.GetAbsolutePath().ToString();
        TaskDialog.Show("Info", $"名称：{e.Name}；\r\n载入：{isLoaded}；\r\n路径：{filePath}");
    }
