    <p>I wasn't exactly sure how to ask this so I made an <a href="http://sscce.org/" rel="nofollow noreferrer">SSCCE</a></p> <p>I have this simple WCF service</p> <pre><code>[ServiceContract] [ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)] public class EmailService { [WebInvoke(UriTemplate = "/SendEmail", Method = "POST", ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Xml)] public bool SendEmail(EmailData data) { try { byte[] fileBinaryContents = Convert.FromBase64String(data.Enc64FileContents); File.WriteAllBytes(data.FileName, fileBinaryContents); return true; } catch (Exception) { return false; } } } [DataContract(Namespace = "http://somenamespace/")] public class EmailData { [DataMember] public string FileName { get; set; } [DataMember] public string EmailAddress { get; set; } [DataMember] public string Enc64FileContents { get; set; } } </code></pre> <p>and I'm trying to get a Winforms client to call the webservice method; this is what I have</p> <pre><code>string URI = " http://localhost:59961/EmailService/SendEmail"; string fileContents = Convert.ToBase64String(File.ReadAllBytes("test.txt")); EmailData emailData = new EmailData { EmailAddress = "foo@bar.com", Enc64FileContents = fileContents, FileName = "test.txt" }; XNamespace ns = "http://somenamespace/"; XElement emailDataElement = new XElement(ns + "EmailData"); emailDataElement.Add(new XElement(ns + "FileName", emailData.FileName)); emailDataElement.Add(new XElement(ns + "Enc64FileContents", emailData.Enc64FileContents)); emailDataElement.Add(new XElement(ns + "EmailAddress", emailData.EmailAddress)); var xml = emailDataElement.ToString(SaveOptions.DisableFormatting); using (WebClient wc = new WebClient()) { wc.Headers[HttpRequestHeader.ContentType] = "application/xml; charset=utf-8"; string response = wc.UploadString(URI, "POST", xml); } </code></pre> <p>now on the service side, some of the properties are null as shown by the following screenshot. <img src="https://i.stack.imgur.com/m63hX.png" alt="enter image description here"></p> <p>Why is it that the <code>FileName</code> has the right value but the others don't ?</p>

    3. CO@Maras it's a super simple text file (has only one word). I also tried sending a normal string instead of the base64 string and that didn't help either.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
