我的代码使用网络浏览器来显示 word、excel 和 powerpoint。不幸的是，每次它试图打开它时，首先会出现一个警告框，询问我是要保存、打开还是取消。我应该如何删除它？

您遇到了浏览器安全问题。您不能在没有用户输入的情况下打开其中可能包含恶意项目的文档。

另外...您需要重构您的代码。您拥有的代码太多了，它们完全相同。

 private string GetFileFromUser(string aFilter){
  openFileDialog1.Filter = aFilter
  openFileDialog1.FilterIndex = 1;
  System.Windows.Forms.HtmlDocument document;
  openFileDialog1.FileName = "";
  openFileDialog1.ShowDialog();
  return openFileDialog1.FileName;
 }

 fileName = GetFileFromUser("Office Documents (*.xls, *.xlsx)|*.xls;*.xlsx");
