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来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：
'无法初始化加载项“删除视图”，因为该类 在加载项程序集中找不到“DeleteViews”。FullClassName 为Revit调用附加应用程序提供入口点。为了 Revit 要运行加载项，您必须确保此类实现 “Autodesk.Revit.UI.ExternalCommand”界面。'
我很确定我的问题是在第二段代码中引用的。我知道我没有正确调用它，但一直无法找到任何解决方案。
如果这是一个愚蠢的问题，我深表歉意，但非常感谢任何帮助我学习的帮助！
感谢您给我的任何帮助
代码：
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，考虑使用反射，而不是自己输入类名：
typeof(YourClassName).FullName
其次，Revit 中的每个命令都需要有自己的类来实现
IExternalCommandusing 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
}
}
}
在执行任何其他操作之前，您应该先阅读 Revit API 入门材料，尤其是 DevTV 和 我的第一个 Revit 插件 视频教程：

那么这个问题和许多其他基本问题将得到预先解答，您将为自己和他人节省一些精力和麻烦。
由于单击按钮时发生事务错误，我需要在 IExternalCommand 之前添加一行。
[Transaction(TransactionMode.Manual)]
我知道这是一篇很旧的文章，但我更喜欢为遇到同样问题的人添加一个答案..
补充一下其他人所说的，验证公共类 CsBGPanel 的名称：IExternalApplication
必须是班级名称
这件事发生在我身上！
这个问题的第一个答案建议使用反射“typeof(YourClassName).FullName”当尝试示例代码时，它会返回一个错误，这是可以理解的，因为奥古斯托说他没有测试他的示例。只是为以后的任何人添加...如果您使用“typeof(DeleteViews).FullName”，您需要将其转换为字符串变量，然后他的示例中的代码才能工作。
我有一个函数，可以在第二个辅助 DLL 中的功能区栏中创建按钮，因此
string thisAssemblyPath = Assembly.GetExecutingAssembly().Location;string thisAssemblyPath = Assembly.GetCallingAssembly().Location;
