            this.CenterToScreen();            this.axWebBrowser1.NavigateComplete2 += new AxSHDocVw.DWebBrowserEvents2_NavigateComplete2EventHandler(this.axWebBrowser1_NavigateComplete2);
            this.Load += new System.EventHandler(this.Form1_Load);
            this.Closed += new System.EventHandler(this.Form1_Closed);
            strFileName = Application.StartupPath+"\\Head_YouTinaSJ.xls";
            if (strFileName.Length != 0)
            {
                refmissing = System.Reflection.Missing.Value;
                oDocument = null;
                axWebBrowser1.Navigate(strFileName, ref refmissing, ref refmissing, ref refmissing, ref refmissing);
            }   public void axWebBrowser1_NavigateComplete2(object sender, AxSHDocVw.DWebBrowserEvents2_NavigateComplete2Event e)
        {
            try
            {
                Object o = e.pDisp;
                Object oDocument = o.GetType().InvokeMember("Document", BindingFlags.GetProperty, null, o, null);
                Object oApplication = o.GetType().InvokeMember("Application", BindingFlags.GetProperty, null, oDocument, null);
                excelapp = (Excel.Application)oApplication;//
                excelapp.DisplayAlerts = false;//些处报错                excelapp.DisplayFormulaBar = false;  //隐藏工具栏            }
            catch (Exception ex)
            {

成熟代码：        //保存到Excel
        public void SaveDataTableToExcel(System.Data.DataTable excelTable,string filePath)
        {
            Microsoft.Office.Interop.Excel.Application app = 
                new Microsoft.Office.Interop.Excel.ApplicationClass();
            try
            {
                //让后台执行设置为不可见
                app.Visible = false;
                //新增加一个工作簿
                Workbook wBook = app.Workbooks.Add(true);
                //如果要打开已有的工作簿，则使用下面的注释语句
                // Workbook wBook = app.Workbooks.Open(@"C:\YourPath\YourWorkbook.xls",
                //    missing, missing, missing, missing, missing, missing, missing,
                //    missing, missing, missing, missing, missing,missing, missing);                //取得一个工作表
                //如果打开了已有的工作簿,也可以这样获取工作表Worksheet wSheet = wBook.ActiveSheet as Worksheet
                Worksheet wSheet = wBook.Worksheets[1] as Worksheet;
                if (excelTable.Rows.Count > 0)
                {
                    int row = 0;
                    row = excelTable.Rows.Count;
                    int col = excelTable.Columns.Count;
                    allsize = row;                    for (int i = 0; i < row; i++)
                    {
                        for (int j = 0; j < col; j++)
                        {
                            string str = excelTable.Rows[i][j].ToString();
                            wSheet.Cells[i + 1, j + 1] = str;
                        }
                        SetMessageText();
                    }
                }                int size = excelTable.Columns.Count;
                for (int i = 0; i < size; i++)
                {
                    wSheet.Cells[1, 1 + i] = excelTable.Columns[i].ColumnName;
                }                //设置禁止弹出保存和覆盖的询问提示框
                app.DisplayAlerts = false;
                app.AlertBeforeOverwriting = false;
                //保存工作簿
                wBook.Save();
                //保存excel文件
                app.Save(filePath + "\\导出一览表.xls");
            }
            catch(Exception err)
            {
                MessageBox.Show("导入Excel出错！错误原因："+ err.Message, "NaviDMS 2.2",
                    MessageBoxButtons.OK, MessageBoxIcon.Information);
            }     
            finally
            {
                //确保Excel进程关闭
                app.Quit();
                app = null;
            }
        }
