例

次の例は、 TryResolveType メソッドの実装を示しています。

// Used at serialization
// Maps any Type to a new xsi:type representation
public override bool TryResolveType(Type type, Type declaredType, DataContractResolver knownTypeResolver, out XmlDictionaryString typeName, out XmlDictionaryString typeNamespace)
{
    string name = type.Name;
    string namesp = type.Namespace;
    typeName = new XmlDictionaryString(XmlDictionary.Empty, name, 0);
    typeNamespace = new XmlDictionaryString(XmlDictionary.Empty, namesp, 0);
    if (!dictionary.ContainsKey(type.Name))
    {
        dictionary.Add(name, typeName);
    }
    if (!dictionary.ContainsKey(type.Namespace))
    {
        dictionary.Add(namesp, typeNamespace);
    }
    return true;
}

注釈

実装内で既知の型解決ロジックを使用する場合は、その参照が knownTypeResolver パラメーターとして渡されます。
