asp.net - 使用 fileuploadcontrol 在 xmlfile 中更新 URL 属性

Question

我有一个像这样的 XMLFile.xml

 <?xml version="1.0" encoding="utf-8" ?>
<items>
<pdf ID="121">

 <URL>www.google.co.in</URL>
 </pdf>
</items>

我有具有路径的文件上传控件。当我单击保存时，它会更改相对于该 ID 的 URL 属性。

  protected void Button1_Click(object sender, EventArgs e)
  {


    XmlDocument xmlDoc = new XmlDocument();
    xmlDoc.Load(Server.MapPath("XMLFile.xml"));


    if (FileUpload1.HasFile)
    {
        try
        {
            //string file = FileUpload1.PostedFile.FileName;
            string filename = Path.GetFileName(FileUpload1.FileName);
            string filepath = Path.GetFullPath(FileUpload1.FileName.ToString());
            Label1.Text = filepath;
            XmlNodeList nodeList = xmlDoc.SelectNodes("/items/pdf[@ID='121']");
            // update MainCategory 
            nodeList[0].ChildNodes[0].InnerText = Label1.Text;


            // Don't forget to save the file
            xmlDoc.Save(Server.MapPath("XMLFile.xml"));
            Response.Write("XML File updated!");
        }


        catch (Exception ex)
        {
            Label1.Text = "Upload status: The file could not be uploaded. The following   error occured: " + ex.Message;
        }
    }
   }
