本文介绍了一种在Revit API中通过FamilyInstance对象获取其所属族名称的方法。使用Transaction开始事务，并通过选取元素的方式得到FamilyInstance实例，进而获取到该实例对应的族名称、实例名称及类别名称。

// 根据族实例FamilyInstance找到Family的方法：FamilyInstance.Symbol.Family
[Transaction(TransactionMode.Manual)]
[Regeneration(RegenerationOption.Manual)]
// [Journaling(JournalingMode.NoCommandData)]
public class cmdFamily : IExternalCommand
{
     public Result Execute(ExternalCommandData cmdData, ref string message, ElementSet elements)
    {
        UIDocument uiDoc = cmdData.Application.ActiveUIDocument;
        Selection selection = uiDoc.Selection;

        Transaction ts = new Transaction(uiDoc.Document, " FamilyName " );
        ts.Start();

        Reference refelem = selection.PickObject(ObjectType.Element, " 选择 " );
        Element el = uiDoc.Document.get_Element(refelem.ElementId);
        FamilyInstance fi = el as FamilyInstance;
        TaskDialog.Show( " title " , fi.Symbol.Family.Name + " | " + fi.Name + " | " + fi.Category.Name);

        ts.Commit();

         return Result.Succeeded;
    }
}
