Body
 

Note that there are some explanatory texts on larger screens.

  1. PODataContractSerializer not Serializing member of class that inherits ISerializable
    text
    copied!<p>I have this class:</p> <pre><code>using System; using System.Collections.Generic; using System.Runtime.Serialization; namespace Grouping { [Serializable] public class Group&lt;T&gt; : HashSet&lt;T&gt; { public Group(string name) { this.name = name; } protected Group(){} protected Group(SerializationInfo info, StreamingContext context):base(info,context) { name = info.GetString("koosnaampje"); } public override void GetObjectData(SerializationInfo info,StreamingContext context) { base.GetObjectData(info,context); info.AddValue("koosnaampje", Name); } private string name; public string Name { get { return name; } private set { name = value; } } } } </code></pre> <p>As it inherits from HashSet it has to implement ISerializable, hence the protected constructor and GetObjectData method. Formerly I serialized and deserialized this class succesfully with the BinaryFormatter.</p> <p>Because I want to be able to inspect the output that is generated by the serializer I want to switch to the DataContractSerializer.</p> <p>I wrote this test:</p> <pre><code>[TestMethod] public void SerializeTest() { var group = new Group&lt;int&gt;("ints"){1,2,3}; var serializer = new DataContractSerializer(typeof (Group&lt;int&gt;)); using (var stream=File.OpenWrite("group1.xml")) { serializer.WriteObject(stream,group); } using (var stream=File.OpenRead("group1.xml")) { group = serializer.ReadObject(stream) as Group&lt;int&gt;; } Assert.IsTrue(group.Contains(1)); Assert.AreEqual("ints",group.Name); } </code></pre> <p>The test fails because the Name property is null! (the integers are (de)serialized correctly though) What is happening?</p> <p>EDIT: it has nothing to do with the name backing field being private. Making it public has the same result.</p>
