c# 导出数据到excel

直接上代码：

        private void button1_MouseDown(object sender, MouseEventArgs e)
        {
            if (e.Button == MouseButtons.Right)
            {
                FormWaiting formWaiting = new FormWaiting();
                formWaiting.Show();
                formWaiting.Focus();
                try
                {
                    SaveFileDialog sfd = new SaveFileDialog();
                    sfd.Filter = "数据文件（*.xls）|*.xls|数据文件（*.xlsx）|*.xlsx";
                    sfd.FilterIndex = 1;//设置默认文件类型显示顺序 
                    sfd.RestoreDirectory = true;//保存对话框是否记忆上次打开的目录 

                    //点了保存按钮进入 
                    if (sfd.ShowDialog() == DialogResult.OK)
                    {
                        string fullName = sfd.FileName.ToString(); //获得文件路径 

                        Excel.Application xlApp = new Excel.Application();
