Revit二次开发之“取得内参BuiltIn名称的方法”

有时候你需要知识某个元素类别对应的内参名称是什么，是取得名称的方法。

using System.Xml;

namespace RevitCodes
{
    [Transaction(TransactionMode.Manual)]
    [Regeneration(RegenerationOption.Manual)]
    public class cmdBuiltIn : IExternalCommand
    {
        public Result Execute(ExternalCommandData cmdData, ref string msg, ElementSet elements)
        {
            UIDocument uiDoc = cmdData.Application.ActiveUIDocument;

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

            Element selectedElement = null;
            //需要首先选择一个元素
            foreach (Element e in uiDoc.Selection.Elements)
            {
                selectedElement = e;
                break;//取得一个测试
            }
            Category category = selectedElement.Category;
            //取得类别内参名的方法
            BuiltInCategory enumCategory = (BuiltInCategory)category.Id.IntegerValue;
            TaskDialog.Show("builtin", enumCategory.ToString());//风管对应OST_DuctCurves

            ts.Commit();

            return Result.Succeeded;
        }
    }
}
