Trying to parse an xml file into an Object in C# aspx.net

Question

I have a problem trying to serialize an XML file into an object. I got this to work in an other project, but this time it does not work. The object and its elements are always empty.

My XML file:

  <ConferenceTextAttributes>
  <_lbl_TitleOfPage_Text>Registration</_lbl_TitleOfPage_Text>
  <_lbl_textBoxInfo_Text>(* mandatory fields)</_lbl_textBoxInfo_Text>
  <_lbl_mrsmr_Text>Mr/Ms:*</_lbl_mrsmr_Text>
  <_txt_mrsmr_Text></_txt_mrsmr_Text>
  <_lbl_title_Text>Title:</_lbl_title_Text>

  </ConferenceTextAttributes>

        b_cancle_Text = _b_cancle_Text;
    }

     public ConferenceTextAttributes()
     {

     }
}

My method to serialize:

public ConferenceTextAttributes LeseMeistenTextAttribute(string sPfad2)
{
    XmlSerializer ser2 = new XmlSerializer(typeof(ConferenceTextAttributes));
    StreamReader sr2 = new StreamReader(sPfad2);
    ConferenceTextAttributes MyTextAttributes = 
        (ConferenceTextAttributes)ser2.Deserialize(sr2);
    sr2.Close();
    return MyTextAttributes;
}

tag name: _lbl_TitleOfPage_Text field name: lbl_TitleOfPage_Text spot the difference. — Renatas M.

There are extra underscores in the field names in the xml. Use XmlElement attributes in you class to specify those.

[XmlElement("_lbl_msmr_text")]
public string lbl_msmr_text { get; set; }
