VSTO 得到Office文档的选中内容（Word、Excel、PPT、Outlook）

原文:VSTO 得到Office文档的选中内容（Word、Excel、PPT、Outlook）

目的：得到在Word、Excel、PPT、Outlook中选中的一段内容。

Word:

private string GetSelectCont()
        {
            string w = "";
            Word.Selection sec = appWord.Selection;
            Word.Words wds = sec.Words;           
            w = wds.Application.Selection.Text;
            return w.Trim();
        }

Outlook:

private string GetSelectCont(Outlook.Inspector Inspector)
       {
            string w = "";

Word.Document document = Inspector.WordEditor;           
            w = document.Application.Selection.Words.Application.Selection.Text;           
            return w.Trim();
       }

注：无法得到标题等之类的选中内容。

PPT:

private string GetSelectCont()
        {
            string w = "";

PowerPoint.Selection sec = appPPT.ActiveWindow.Selection;
            string word = sec.TextRange.Text;
            return word.Trim();
        }

Excel:

private string GetSelectCont()
        {
            string w = "";
            object[,] result;
            object res1;
            string res2;
            Excel.Workbook wbook = Globals.ThisAddIn.Application.ActiveWorkbook;  //当前活动workbook
            Excel.Worksheet wsheet = (Excel.Worksheet)wbook.ActiveSheet;          //当前活动sheet 
            Excel.Range range = (Excel.Range)wsheet.Application.Selection;      //当前选中的cells

int count = range.Count;
            res1 = (object)range.Value2;
            //如果选中多个单元格
             if (count > 1)
             {
                 int row_count = range.Rows.Count;
                 int col_count = range.Columns.Count;
                 result = (object[,])res1;
                 for (int i = 1; i <= row_count; i++)
                 {
                     for (int j = 1; j <= col_count; j++)
                     {
                         if (result[i, j] != null)
                         {
                             w += (string)result[i, j] + " ";
                         }
                     }
                 }
             }
             else {
                 //如果选中单个
                 if (res1 == null)
                 {
                     w = "";
                 }
                 else {                   
                     res2 = res1.ToString();
                     w = res2;
                 }
             }
            return w.Trim();
        }

注：Excel比较复杂，这只能得到选中单个或多个单元格的内容，却不能得到某个单元格中mark起来的内容，正在查找解决办法。。。
