Excel-DNA项目只用1个文件实现Ribbon CustomUI和CustomTaskpane定制【C#版】

Excel-DNA项目中的自定义功能区和自定义任务窗格需要用到各种命名空间、添加所需文件，才能实现。后来我发现可以把所有代码都写在Class1.cs这个默认文件中。

大家可以在Visual Studio中创建一个类库项目（.Net Framework），然后把默认的Class1.cs中的代码整体替换为下面我贴的这个代码。然后启动调试，就可以看到自定义功能区和任务窗格了。

 using System.Runtime.InteropServices;
 using ExcelDna.Integration;
 using ExcelDna.Integration.CustomUI;
 using Excel = Microsoft.Office.Interop.Excel;
 using System.Windows.Forms;
 namespace Excel_DNA_Template_CS
 {
     [ComVisible(true)]
     public class Class1 :ExcelRibbon,IExcelAddIn
     {
         public IRibbonUI R;
         public override string GetCustomUI(string RibbonID)
         {
             string xml = @"<customUI xmlns='http://schemas.microsoft.com/office/2009/07/customui' onLoad='OnLoad'>
     <ribbon startFromScratch='false'>
         <tabs>
             <tab id='Tab1' label='RibbonXmlEditor'>
                 <group id='Group1' label='Author:ryueifu'>
                     <button id='Button1' label='CTP' imageMso='C' onAction='Button1_Click'/>
                     <button id='Button2' label='UnLoad' imageMso='U' onAction='Button2_Click'/>
                 </group>
             </tab>
         </tabs>
     </ribbon>
 </customUI>";
             return xml;
         }
         public void OnLoad(IRibbonUI ribbon)
         {
             R = ribbon;
             R.ActivateTab(ControlID: "Tab1");
         }
         public void Button1_Click(IRibbonControl control)
         {
             Module1.ctp.Visible = !Module1.ctp.Visible;
         }
         public void Button2_Click(IRibbonControl control)
         {
             Excel.AddIn ThisAddin = (ExcelDnaUtil.Application as Excel.Application).AddIns["Excel_DNA_Template_CS"];
             ThisAddin.Installed= false;
         }
         void IExcelAddIn.AutoClose()
         {
             Module1.DisposeCTP();
         }

         void IExcelAddIn.AutoOpen()
         {
             Module1.CreateCTP();
         }
     }
     public static class Module1
     {
         public static UserControl uc;
         public static CustomTaskPane ctp;
         public static void CreateCTP()
         {
             uc = new UserControl();
             ctp = CustomTaskPaneFactory.CreateCustomTaskPane(userControl: uc, title: "CTP");
             ctp.DockPosition = MsoCTPDockPosition.msoCTPDockPositionRight;
             ctp.Visible = true;
         }
         public static void DisposeCTP()
         {
             ctp.Delete();
             ctp = null;
         }
     }
 }
