DataContractResolver.cs

Ambil alih metode ini untuk memetakan nama dan namespace yang ditentukan xsi:type ke jenis kontrak data selama deserialisasi.

public:
 abstract Type ^ ResolveName(System::String ^ typeName, System::String ^ typeNamespace, Type ^ declaredType, System::Runtime::Serialization::DataContractResolver ^ knownTypeResolver);

[System.Diagnostics.CodeAnalysis.RequiresDynamicCode("Data Contract Serialization and Deserialization might require types that cannot be statically analyzed.")]

Contoh

Contoh berikut menunjukkan implementasi ResolveName metode .

// 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;
    }
}
