本文演示如何获取Revit文件中的墙类型。

## 1.用Revit绘制模型 ##

该模型中包含墙和门。

## 2.获取墙类型 ##

### 2.1 OfCategory(BuiltInCategory.OST\_Walls) ###

using Autodesk.Revit.Attributes;
    using Autodesk.Revit.DB;
    using Autodesk.Revit.UI;
    using System.Windows.Forms;
    
    namespace RevitAddin3
    {
        [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);
                var walls = collector.OfCategory(BuiltInCategory.OST_Walls);
                        
                string name = "";
                foreach (var item in walls)
                {
                    name += item.Name + "\n";
                }            
                MessageBox.Show(name, "信息"); 
                return Result.Succeeded;
            }
        }  
    }

执行结果：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2xpeWF6aGVuMjAxMQ_size_16_color_FFFFFF_t_70 1][]

### 2.2 OfClass(typeof(WallType)) ###

将语句

var walls = collector.OfCategory(BuiltInCategory.OST_Walls);

替换为

var walls = collector.OfClass(typeof(WallType));

执行结果相同。

### 2.3 OfClass(typeof(Wall)) ###

将语句

var walls = collector.OfCategory(BuiltInCategory.OST_Walls);

替换为

var walls = collector.OfClass(typeof(Wall));

执行结果
