This method also specifies the root XML element and namespace in two XmlDictionaryString parameters as well as a list of known types that may be present in the object graph.

DataContractSerializer(Type)

Source:

DataContractSerializer.cs

Initializes a new instance of the DataContractSerializer class to serialize or deserialize an object of the specified type.

C#

public DataContractSerializer(Type type);

Parameters

type

Type

The type of the instances that are serialized or deserialized.

Examples

The following example creates an instance of the DataContractSerializer that specifies the type to serialize or deserialize.

C#

public static void Constructor1()
{
    // Create an instance of the DataContractSerializer.
    DataContractSerializer ser =
        new DataContractSerializer(typeof(Person));
    // Other code not shown.
}

DataContractSerializer(Type, String, String, IEnumerable<Type>)

Source:

DataContractSerializer.cs

Initializes a new instance of the DataContractSerializer class to serialize or deserialize an object of the specified type. This method also specifies the root XML element and namespace in two string parameters as well as a list of known types that may be present in the object graph.

C#

public DataContractSerializer(Type type, string rootName, string rootNamespace, System.Collections.Generic.IEnumerable<Type>? knownTypes);

Parameters

type

Type

The type of the instances that are serialized or deserialized.

rootName

String

The root element name of the content.

rootNamespace

String

The namespace of the root element.

knownTypes

IEnumerable<Type>

An IEnumerable<T> of Type that contains the types that may be present in the object graph.

Examples

The following example creates an instance of the DataContractSerializer that specifies the type to serialize or deserialize as well as the XML name and namespace to read from or write to the XML document. The code also creates an instance of a IEnumerable<T> to contain the known types used during serialization or deserialization.

C#

public static void Constructor5()
{
    // Create a generic List of types and add the known types
    // to the collection.
    List<Type> knownTypeList = new List<Type>();
    knownTypeList.Add(typeof(PurchaseOrder));
    knownTypeList.Add(typeof(PurchaseOrderV3));

    DataContractSerializer ser =
        new DataContractSerializer(
        typeof(Person),
        "Customer",
        @"http://www.contoso.com",
        knownTypeList);

    // Other code not shown.
}

DataContractSerializer(Type, XmlDictionaryString, XmlDictionaryString)

Source:

DataContractSerializer.cs

Initializes a new instance of the DataContractSerializer class to serialize or deserialize an object of the specified type using the XML root element and namespace specified through the parameters of type XmlDictionaryString.

C#

public DataContractSerializer(Type type, System.Xml.XmlDictionaryString rootName, System.Xml.XmlDictionaryString rootNamespace);

Parameters

type

Type

The type of the instances that are serialized or deserialized.

rootName

XmlDictionaryString

An XmlDictionaryString that contains the root element name of the content.

rootNamespace

XmlDictionaryString

An XmlDictionaryString that contains the namespace of the root element.

Examples

The following example creates an instance of the DataContractSerializer that specifies the type to serialize or deserialize as well as the XML name and namespace (as XmlDictionaryString objects) to read from or write to the XML document.

C#

public static void Constructor4()
{
    // Create an instance of the DataContractSerializer
    // specifying the type, and name and
    // namespace as XmlDictionaryString objects.

    // Create an XmlDictionary and add values to it.
    XmlDictionary d = new XmlDictionary();
    XmlDictionaryString name_value = d.Add("Customer");
    XmlDictionaryString ns_value = d.Add("http://www.contoso.com");

    // Create the serializer.
    DataContractSerializer ser =
        new DataContractSerializer(
        typeof(Person),
        name_value,
        ns_value);
    // Other code not shown.
}

DataContractSerializer(Type, String, String)

Source:

DataContractSerializer.cs

Initializes a new instance of the DataContractSerializer class to serialize or deserialize an object of the specified type using the supplied XML root element and namespace.

C#

public DataContractSerializer(Type type, string rootName, string rootNamespace);

Parameters

public static void Constructor3()
{
    // Create an instance of the DataContractSerializer
    // specifying the type, and name and
    // namespace as strings.
    DataContractSerializer ser =
        new DataContractSerializer(
        typeof(Person),
        "Customer",
        "http://www.contoso.com");
