"Message":"Invalid JSON primitive: RecordId."
<p>getting error in ajax call from jquery.</p>

<p>here is my jquery function</p>

<pre><code>function DeleteItem(RecordId, UId, XmlName, ItemType, UserProfileId) {
    var obj = {
    RecordId: RecordId,
    UserId: UId,
    UserProfileId: UserProfileId,
    ItemType: ItemType,
    FileName: XmlName
};
var json = Sys.Serialization.JavaScriptSerializer.serialize(obj);

$.ajax({
    type: "POST",
    url: "EditUserProfile.aspx/DeleteRecord",
    data: json,
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    async: true,
    cache: false,
    success: function(msg) {
        if (msg.d != null) {
            RefreshData(ItemType, msg.d);
        }
    },
    error: function(XMLHttpRequest, textStatus, errorThrown) {
        alert("error occured during deleting");
    }
});
}
</code></pre>

<p>and this is my webmethod</p>

<pre><code>[WebMethod]
public static string DeleteRecord(Int64 RecordId, Int64 UserId, Int64 UserProfileId, string ItemType, string FileName) {
    try {
        string FilePath = HttpContext.Current.Server.MapPath(FileName);

        XDocument xmldoc = XDocument.Load(FilePath);
        XElement Xelm = xmldoc.Element("UserProfile");
        XElement parentElement = Xelm.XPathSelectElement(ItemType + "/Fields");

        (from BO in parentElement.Descendants("Record")
         where BO.Element("Id").Attribute("value").Value == RecordId.ToString()
         select BO).Remove();
        XDocument xdoc = XDocument.Parse(Xelm.ToString(), LoadOptions.PreserveWhitespace);
        xdoc.Save(FilePath);

        UserInfoHandler obj = new UserInfoHandler();
        return obj.GetHTML(UserId, UserProfileId, FileName, ItemType, RecordId, Xelm).ToString();
    } catch (Exception ex) {
        HandleException.LogError(ex, "EditUserProfile.aspx", "DeleteRecord");
    }
    return "success";
}
