为了避嫌，贴上代码　重写ReportExport，导出ＥＸＣＥＬpublic void ReportExport(object sender, ReportExportEventArgs e)
        {
            string fileName = "c:\\output.xls";
            SaveFileDialog fd = new SaveFileDialog();
            fd.DefaultExt = ".XLS";           // 扩展名
            fd.FileName = fileName;   // 默认值
            if (fd.ShowDialog() == DialogResult.Cancel) return;            fileName = fd.FileName;
            if (File.Exists(fileName))
            {
                FileInfo fi = new FileInfo(fd.FileNames[0]);
                if (fi.IsReadOnly)
                {
                    MessageBox.Show(fd.FileName + "文件只读"); return;
                }
            }            Warning[] warnings;
            string[] streamids;
            string mimeType;
            string encoding;
            string extension;            byte[] bytes = (sender as ReportViewer).LocalReport.Render("Excel", null, out mimeType, out encoding, out extension,out streamids, out warnings);
            FileStream fs = new FileStream(fileName, FileMode.Create);
            fs.Write(bytes, 0, bytes.Length);
            fs.Close();            MessageBox.Show( "成功导出："+fileName);
        }
