Serileştirme sırasında bir veri sözleşmesi türünü bir xsi:type ad ve ad alanıyla eşlemek için bu yöntemi geçersiz kılın.

Örnekler

Aşağıdaki örnekte yönteminin bir uygulaması gösterilmektedir TryResolveType .

// 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;
}

Açıklamalar

Uygulamanızın içinde bilinen tür çözümleme mantığını kullanmak istiyorsanız, parametre olarak knownTypeResolver buna bir başvuru geçirilir.
