Beispiele

Das folgende Beispiel zeigt eine Implementierung der ResolveName Methode.

// Used at deserialization
// Allows users to map xsi:type name to any Type
public override Type ResolveName(string typeName, string typeNamespace, Type declaredType, DataContractResolver knownTypeResolver)
{
    XmlDictionaryString tName;
    XmlDictionaryString tNamespace;
    if (dictionary.TryGetValue(typeName, out tName) && dictionary.TryGetValue(typeNamespace, out tNamespace))
    {
        return this.assembly.GetType(tNamespace.Value + "." + tName.Value);
    }
    else
    {
        return null;
    }
}

Hinweise

Wenn Sie die bekannte Typauflösungslogik in Ihrer Implementierung verwenden möchten, wird ein Verweis darauf als knownTypeResolver Parameter übergeben.
