      <para>Apply the <see cref="T:System.Runtime.Serialization.DataMemberAttribute" /> attribute in conjunction with the <see cref="T:System.Runtime.Serialization.DataContractAttribute" /> to identify members of a type that are part of a data contract. One of the serializers that can serialize data contracts is the <see cref="T:System.Runtime.Serialization.DataContractSerializer" />. </para>
      <para>The data contract model is an "opt-in" model. Applying the <see cref="T:System.Runtime.Serialization.DataMemberAttribute" /> to a field or property explicitly specifies that the member value will be serialized. In contrast, the <see cref="T:System.Runtime.Serialization.Formatters.Binary.BinaryFormatter" /> serializes public and private fields of a type, and the <see cref="T:System.Xml.Serialization.XmlSerializer" /> serializes only public fields and properties of a type. </para>
      <block subset="none" type="note">
        <para>You can apply the <see cref="T:System.Runtime.Serialization.DataMemberAttribute" /> to private fields or properties. Be aware that the data returned by the member (even if it private) will be serialized and deserialized, and thus can be viewed or intercepted by a malicious user or process. </para>
      </block>
      <para>By default, the CLR member name is used as the name of the data member. By setting the <see cref="P:System.Runtime.Serialization.DataMemberAttribute.Name" /> property, you can customize the name of the data member. This can be used to provide a name that may not be allowed as a CLR member name. When mapping to XML using the <see cref="T:System.Runtime.Serialization.DataContractSerializer" />, this name is used as the name of the schema element in a type.</para>
      <block subset="none" type="note">
        <para>Properties to which the <see cref="T:System.Runtime.Serialization.DataMemberAttribute" /> attribute has been applied must have both get and set fields; they cannot be get-only or set-only.</para>

          <attribution license="cc4" from="Microsoft" modified="false" />
          <para>In the dnprdnshort, types have a concept of default values. For example, for any reference type the default value is null, and for an integer type it is 0. It is occasionally desirable to omit a data member from the serialized data when it is set to its default value. To do this, set the <see cref="P:System.Runtime.Serialization.DataMemberAttribute.EmitDefaultValue" /> property to false (it is true by default). </para>
          <block subset="none" type="note">
            <para>Setting the <see cref="P:System.Runtime.Serialization.DataMemberAttribute.EmitDefaultValue" /> property to false is not a recommended practice. It should only be done if there is a specific need to do so (such as for interoperability or to reduce data size).</para>

          <para>This property is used to override the default name of the data member that is derived from the name of the member annotated with the <see cref="T:System.Runtime.Serialization.DataMemberAttribute" />. </para>
          <para>The <see cref="P:System.Runtime.Serialization.DataMemberAttribute.Name" /> property enables you to use names that are not permitted as common language runtime (CLR) identifiers. In addition, this property enables the type author to define a data member name separate from the CLR member name. This separate definition helps in versioning scenarios (changing the CLR member name without breaking the data contract) and allows a different naming convention for data contact members and CLR members. </para>
