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。

 1 using System.Runtime.InteropServices;
 2 using ExcelDna.Integration;
 3 using ExcelDna.Integration.CustomUI;
 4 using Excel = Microsoft.Office.Interop.Excel;
 5 using System.Windows.Forms;
 6 namespace Excel_DNA_Template_CS
 7 {
 8     [ComVisible(true)]
 9     public class Class1 :ExcelRibbon,IExcelAddIn
10     {
11         public IRibbonUI R;
12         public override string GetCustomUI(string RibbonID)
13         {
14             string xml = @"<customUI xmlns='http://schemas.microsoft.com/office/2009/07/customui' onLoad='OnLoad'>
15     <ribbon startFromScratch='false'>
16         <tabs>
17             <tab id='Tab1' label='RibbonXmlEditor'>
18                 <group id='Group1' label='Author:ryueifu'>
19                     <button id='Button1' label='CTP' imageMso='C' onAction='Button1_Click'/>
