Acess拒绝了asp.net中的错误

问题描述

我已经制作了一个简单的页面，将新闻添加到具有值标题和链接重定向的网站。

我为此目的使用了xml。

我在本地主机上运行代码它工作正常，但是当我在网站上部署时，只要我试图保存文件就会显示aceess拒绝错误。

我的XML文件是

I have made a simple page to add news to a site which has values title and link to be redirect.
I Have use xml for the purpose.
When i run code on local host it is working perfectly but when i deploy it on website it shows aceess denied error whenever i''m trying to save the file.
My XML file is

<?xml version="1.0" encoding="utf-8"?>
<newsInfo>
  <news>
    <id>1</id>
    <title>AGM (Annual General Meeting) was held on 16th June (Saturday), New Executive Committee has taken charge.</title>
    <link>../contact.aspx</link>
  </news>
  <news>
    <id>2</id>
    <title>IETE Surat  center is thinking to hold its first examination center at SURAT in December 2012, For more Information please  send your feedback here.</title>
    <link>../contact.aspx</link>
  </news>
</newsInfo>

和代码是

And code is

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            if (Session["7856_UserID"] == null)
            {
                Response.Redirect("Default.aspx");

            }
            else
            {
                lblUserName.Text = "Welcome " + Convert.ToString(Session["7856_UserID"]) + "!";
                fillgrid();
            }
        }
    }
    protected DataTable retriveDetailsFromXML()
    {

        var com = from committee in xmlDoc.Descendants("news")
                  select new

    }

    {

        if (Session["KeyValue"] != null)
        {
            Int32 key = Convert.ToInt32(Session["KeyValue"]);
            XDocument doc = XDocument.Load(Server.MapPath("~\\Data\\newsInfo.xml"));
            IEnumerable<XElement> com = doc.Elements("newsInfo").Elements("news");
            var oCom = (from member in com
                        where member.Element("id").Value == key.ToString()
                        select member).SingleOrDefault();
            oCom.SetElementValue("title", e.NewValues[0]);
            oCom.SetElementValue("link", e.NewValues[1]);

        fillgrid();


        ASPxGridView1.CancelEdit();
        e.Cancel = true;

    }
    protected void ASPxGridView1_StartRowEditing(object sender, DevExpress.Web.Data.ASPxStartRowEditingEventArgs e)

        doc.Save(Server.MapPath("~\\Data\\newsInfo.xml"));
        fillgrid();

        e.Cancel = true;
