我对 C# 和编码非常陌生。如果可能的话，我正在寻求一些帮助，以弄清楚如何修复这段代码以使其正常工作。

他们单独工作。我可以在功能区上创建一个新按钮并执行标准的 hello world。我还有一个宏，可以在其中成功删除所有工作表和视图，但尝试将两者结合起来会造成很大的困难！代码构建正常，但我在 revit 中收到此错误：

'未能初始化加载项“删除视图”，因为在加载项程序集中找不到类“DeleteViews”。FullClassName 为 Revit 调用加载项应用程序提供了入口点。要让 Revit 运行加载项，您必须确保此类实现“Autodesk.Revit.UI.ExternalCommand”接口。

我很确定我的问题是在第二段代码中引用。我知道我没有正确调用它，但找不到任何解决方案。

抱歉，如果这是一个愚蠢的问题，但非常感谢任何帮助我学习的帮助！

感谢你给与我的帮助

编码：

namespace BGPanel
{
public class CsBGPanel : IExternalApplication
{
    public UIDocument ActiveUIDocument { get; private set; }
    public Result OnStartup(UIControlledApplication application)
    {
        RibbonPanel ribbonPanel = application.CreateRibbonPanel("Tools");

        string thisAssemblyPath = Assembly.GetExecutingAssembly().Location;
        PushButtonData buttonData = new PushButtonData("cmdDeleteViews",
           "Delete Views", thisAssemblyPath, "BGPanel.DeleteViews");

        PushButton pushButton = ribbonPanel.AddItem(buttonData) as PushButton;

        pushButton.ToolTip = "Delete all sheets, schedules & views except structural plans";

        Uri uriImage = new Uri(@"C:\Revit_API\Revit_2015\32px-Broom.png");
        BitmapImage largeImage = new BitmapImage(uriImage);
        pushButton.LargeImage = largeImage;

        return Result.Succeeded;
    }

         public void DeleteViews()
    {
        UIDocument uidoc = this.ActiveUIDocument;
        Document doc = uidoc.Document;

        FilteredElementCollector collector = new FilteredElementCollector(doc);
        ICollection<Element> collection = collector.OfClass(typeof(View)).ToElements();

        using (Transaction t = new Transaction(doc, "Delete Views"))
        {
            t.Start();

            int x = 0;

            foreach (Element e in collection)
            {
                try
                {
                    View view = e as View;

                    switch (view.ViewType)
                    {
                        case ViewType.FloorPlan:
                            break;
                        case ViewType.EngineeringPlan:
                            break;
                        case ViewType.ThreeD:
                            break;
                        default:
                            doc.Delete(e.Id);
                            x += 1;
                            break;
                    }
                }
                catch (Exception ex)
                {
                    View view = e as View;
                    TaskDialog.Show("Error", e.Name + "\n" + "\n" + ex.Message);
                    TaskDialog.Show("Error", ex.Message);
                }
            }
            t.Commit();

            TaskDialog.Show("BG_API DeleteViews", "Views Deleted: " + x.ToString());
        }

    }
    public Result OnShutdown(UIControlledApplication application)
    {
        return Result.Succeeded;
    }
}
}

首先，代替自己输入类名，考虑使用反射，如：

typeof(YourClassName).FullName

其次，Revit 中的每个命令都需要自己的类来实现IExternalCommand. 我还没有测试，但你的代码应该是这样的：

using System;
using System.Collections.Generic;
using System.Reflection;
using System.Windows.Media.Imaging;

using Autodesk.Revit.DB;
using Autodesk.Revit.UI;

namespace BGPanel
{
  public class CsBGPanel : IExternalApplication
  {
    public Result OnStartup(UIControlledApplication application)
    {
      RibbonPanel ribbonPanel = application.CreateRibbonPanel("Tools");

      string thisAssemblyPath = Assembly.GetExecutingAssembly().Location;
      PushButtonData buttonData = new PushButtonData("cmdDeleteViews",
         "Delete Views", thisAssemblyPath, typeof(DeleteViews).FullName);

      PushButton pushButton = ribbonPanel.AddItem(buttonData) as PushButton;

      pushButton.ToolTip = "Delete all sheets, schedules & views except structural plans";

      Uri uriImage = new Uri(@"C:\Revit_API\Revit_2015\32px-Broom.png");
      BitmapImage largeImage = new BitmapImage(uriImage);
      pushButton.LargeImage = largeImage;

      return Result.Succeeded;
    }

    public Result OnShutdown(UIControlledApplication application)
    {
      return Result.Succeeded;
    }
  }

  public class DeleteViews : IExternalCommand
  {
    // this will not work...
    //public UIDocument ActiveUIDocument { get; private set; }

    public Result Execute(ExternalCommandData commandData, ref string message, ElementSet elements)
    {
      UIDocument uidoc = commandData.Application.ActiveUIDocument; //this.ActiveUIDocument;
      Document doc = uidoc.Document;

      FilteredElementCollector collector = new FilteredElementCollector(doc);
      ICollection<Element> collection = collector.OfClass(typeof(View)).ToElements();

      using (Transaction t = new Transaction(doc, "Delete Views"))
      {
        t.Start();

        int x = 0;

        foreach (Element e in collection)
        {
          try
          {
            View view = e as View;

            switch (view.ViewType)
            {
              case ViewType.FloorPlan:
                break;
              case ViewType.EngineeringPlan:
                break;
              case ViewType.ThreeD:
                break;
              default:
                doc.Delete(e.Id);
                x += 1;
                break;
            }
          }
          catch (Exception ex)
          {
            View view = e as View;
            TaskDialog.Show("Error", e.Name + "\n" + "\n" + ex.Message);
            TaskDialog.Show("Error", ex.Message);
          }
        }
        t.Commit();

        TaskDialog.Show("BG_API DeleteViews", "Views Deleted: " + x.ToString());
      }
      return Result.Succeeded; // must return here
    }
  }
}

您应该先阅读 Revit API 入门资料，然后再进行任何其他操作，尤其是DevTV和My First Revit Plugin视频教程：

然后这个问题和许多其他基本问题将在前面得到解答，您将节省自己和他人的一些精力和头疼的问题。

由于单击按钮时出现事务错误，我需要在 IExternalCommand 之前添加一行。

[Transaction(TransactionMode.Manual)]
