DataContractResolver.ResolveName Metoda

Definice

Obor názvů:

System.Runtime.Serialization

Sestavení:

netstandard.dll, System.Runtime.Serialization.Xml.dll

Zdroj:

DataContractResolver.cs

Přepište tuto metodu pro mapování zadaného xsi:type názvu a oboru názvů na datový typ kontraktu během deserializace.

Příklady

Následující příklad ukazuje implementaci ResolveName metody.

// 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;
    }
}

Poznámky

Pokud chcete ve své implementaci použít známou logiku překladu typů, předá se jako parametr odkaz.knownTypeResolver
