DataContractResolver::ResolveName Method (String^, String^, Type^, DataContractResolver^)

.NET Framework (current version)

Override this method to map the specified xsi:type name and namespace to a data contract type during deserialization.

Namespace: System.Runtime.Serialization
Assembly: System.Runtime.Serialization (in System.Runtime.Serialization.dll)

Syntax

C++

public:
virtual Type^ ResolveName(
	String^ typeName,
	String^ typeNamespace,
	Type^ declaredType,
	DataContractResolver^ knownTypeResolver
) abstract

Parameters

typeName: Type: System::String^
The xsi:type name to map.

typeNamespace: Type: System::String^
The xsi:type namespace to map.

declaredType: Type: System::Type^
The type declared in the data contract.

knownTypeResolver: Type: System.Runtime.Serialization::DataContractResolver^
The known type resolver.

Return Value

Type: System::Type^

The type the xsi:type name and namespace is mapped to.

Remarks

If you want to use the known type resolution logic inside your implementation, a reference to it is passed in as the knownTypeResolver parameter.

Examples

The following example shows an implementation of the ResolveName method.

// 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;
    }
}
