问我们是否需要手动将xml添加到我们的解决方案中？

EN

using (var store = IsolatedStorageFile.GetUserStoreForApplication())
{
  using (var fs = store.OpenFile("abc.xml", FileMode.OpenOrCreate, FileAccess.ReadWrite))
  {
    var root = new XElement("User");
    var Mobile_Number = new XElement("Mobile_NUmber", txtMobNum.Text);

    var Sec_Ques = new XElement("Sec_Ques", secQues);
    var xDoc = new XDocument();
    root.Add(Mobile_Number, Sec_Ques);
    xDoc.Add(root);
    xDoc.Save(fs);
    fs.Close();
  }                
}
