这是一个如何使用文件上传控件的简单示例：

This is a simple example of how you can use a file upload control:

try
{
       //here you are specifying where the file will be saved and then saving the file
       string filename = "A path on the machine" + FileUpload1.FileName.ToString();
       FileUpload1.SaveAs(filename);

       FileInfo file = new FileInfo(filename);

           //here you are checking if the file exists before going on
           if (file.Exists)
           {
               String conString = "";
               String connstr = "";

               //this is just checking the file extension and is optional
               if (filename.EndsWith(".xlsx"))
               {
               }
           }
}
catch (Exception e)
{
}
