在插件开发过程中，随着功能越来越多，用户找寻功能入口将变得越来越困难，在Excel催化剂 ，将采用遍历所有功能的方式，让用户可以轻松使用简单的查找功能找到想要功能所在位置，查找的范围有：功能按钮的显示名称、功能说明等。
按钮功能查找关键词文本来源
这个遍历功能区按钮属性，不确定在xml功能区中能否实现，在设计器功能区，因其已经被强类型为一个类对象，用反射技术可以将这个Ribbon类下所有的控件及属性给遍历出来。详细可参考功能第78波说明。
功能区效果
同样地，自定义函数也可以用遍历的方式，列出所有自定义函数。前提是自定义函数是ExcelDna框架开发的。
自定义函数效果
代码实现
给用户一个按钮，点击后遍历到工作表中。
private void btnShowFeatures_Click(object sender, RibbonControlEventArgs e)
{
try
{
Common.ExcelApp.ScreenUpdating = false;
Common.ExcelApp.DisplayAlerts = false;
RibbonMenu ribbonMenu = sender as RibbonMenu;
GroupVisibleSetting groupVisibleSetting = new GroupVisibleSetting()
{
CurrentRibbon = this
};
groupVisibleSetting.ListTabFunctionInfo();
//遍历自定义函数清单
UdfListInfo.ListUdfInfo();
}
catch (Exception ex)
{
Common.OutMsgError(ex);
}
finally
{
Common.ExcelApp.ScreenUpdating = true;
Common.ExcelApp.DisplayAlerts = true;
}
}
做了个类，用于访问功能区的信息，里面用了反射技术，因笔者水平也是比较菜，是笔者师傅给予帮助下实现的，详细技术要点也讲不清，有兴趣深入的可以自行百度学习。

同样地在自定义函数方面，通过在自定义函数里作了一个自定义函数，专门用于遍历自定义函数的属性，已经开源在自定义函数项目中。
using System;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Text;
using Excel = Microsoft.Office.Interop.Excel;
using Microsoft.Office.Tools.Excel;
namespace Excel催化剂
{
class UdfListInfo
{
private static string shtName = "功能清单";
internal static void ListUdfInfo()
{
try
{
Excel.Worksheet sht = Common.ExcelApp.ActiveWorkbook.Worksheets[shtName];
DataTable dt = new DataTable();
dt.Columns.Add("函数类别");
dt.Columns.Add("函数名称");
dt.Columns.Add("函数注释");
var result = Common.ExcelApp.Run("ListUdfDesc");
if (result is Array)
{
var arrResult = Utilities.ArrayUtility.ConvertExcelArrayToDotNetArray(result as Array);
foreach (var item in arrResult)
{
var strSplits = item.ToString().Split(new string[] { "#|#" }, StringSplitOptions.RemoveEmptyEntries);
if (strSplits.Length == 3)
{
DataRow dr = dt.NewRow();
dr[0] = strSplits[0];
dr[1] = strSplits[1];
dr[2] = strSplits[2];
dt.Rows.Add(dr);
}
}
Excel.Range listRange = sht.ListObjects[shtName].Range;
Excel.Range firstCell = listRange.Offset[0, listRange.Columns.Count + 2].Cells[1, 1];
Worksheet vstoSht = Globals.Factory.GetVstoObject(sht);
var listObject = vstoSht.Controls.AddListObject(firstCell, "自定义函数清单");
Common.OutputDataToListObject(listObject, dt, false);
}
}
catch (Exception)
{
}
}
}
}
上述代码中，在VSTO项目里，仅需用Application.Run就可以访问到xll里的自定义函数ListUdfDesc，同时有个小要点是自定义函数返回的数组，下标是从1开始的Excel特有的，和.net的0为下标的不一样，需要作下转换。
var arrResult = Utilities.ArrayUtility.ConvertExcelArrayToDotNetArray(result as Array);
public static object ListUdfDesc()
{
List<string> list = new List<string>();
var funcs = ExcelRegistration.GetExcelFunctions();
foreach (var funcInfo in funcs)
{
string name = funcInfo.FunctionAttribute.Name;
string desc = funcInfo.FunctionAttribute.Description.Replace("Excel催化剂出品，必属精品！", "");
string catalog = funcInfo.FunctionAttribute.Category;
if (!string.IsNullOrEmpty( catalog))
{
list.Add($"{catalog}#|#{name}#|#{desc}");
}
}
if (list.Count>0)
{
return list.ToArray();
}
else
{
return string.Empty;
}
}
public static object[] ConvertExcelArrayToDotNetArray(Array arr)
{
int lb = arr.GetLowerBound(0);
var ret = new object[arr.GetUpperBound(0) - lb + 1];
for (int ix = 0; ix < ret.Length; ++ix)
{
ret[ix] = arr.GetValue(ix + lb);
}
return ret;
}
结语
使用遍历的方式，让用户可以更轻松地查找相应功能，将极大地提升查找功能的友好度，本篇用到反射技术，比较高级的技术，若代码不甚明白，可自行进行相关知识点的学习补充。
再一次验证了VSTO给一般开发者带来的便利性，特别是在设计器功能区上，带来了强类型的Ribbon类，可轻松访问此类里的所有对象，而增加此类的内容，仅需类似Winform那般拖拉控件即可完成，敏捷开发首选。
