本文演示如何获取Revit文件中的门的类型。

## 1.用Revit绘制模型 ##

该模型中包含墙和门。

### 2.获取门类型 ###

using Autodesk.Revit.Attributes;
    using Autodesk.Revit.DB;
    using Autodesk.Revit.DB.Structure;
    using Autodesk.Revit.UI;
    using System.Windows.Forms;
    
    namespace RevitAddin4
    {
        [TransactionAttribute(TransactionMode.Manual)]
        public class RevitAddin : IExternalCommand
        {
            public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
            {
                UIDocument uiDoc = commandData.Application.ActiveUIDocument;
                Document doc = uiDoc.Document;
                FilteredElementCollector collector = new FilteredElementCollector(doc);
                collector.OfCategory(BuiltInCategory.OST_Doors);
                string str = "";
                foreach (var item in collector)
                {
                    str += item.Name + "\n";
                }
                MessageBox.Show(str, "信息");
              
                return Result.Succeeded;
            }
        }
    }

执行结果:

将上例中的

collector.OfCategory(BuiltInCategory.OST_Doors);

替换为

ElementCategoryFilter filter = new ElementCategoryFilter(BuiltInCategory.OST_Doors);
    collector.WherePasses(filter);

执行结果相同。
