IDataContractSurrogate.GetReferencedTypeOnImport Method

public:
 Type ^ GetReferencedTypeOnImport(System::String ^ typeName, System::String ^ typeNamespace, System::Object ^ customData);

public Type GetReferencedTypeOnImport(string typeName, string typeNamespace, object customData);

abstract member GetReferencedTypeOnImport : string * string * obj -> Type

Public Function GetReferencedTypeOnImport (typeName As String, typeNamespace As String, customData As Object) As Type

The Type to use for the referenced type.

The following example shows an implementation of the GetReferencedTypeOnImport method.

public Type GetReferencedTypeOnImport(string typeName,
    string typeNamespace, object customData)
{
    Console.WriteLine("GetReferencedTypeOnImport invoked");
    // This method is called on schema import.
    // If a PersonSurrogated data contract is
    // in the specified namespace, do not create a new type for it
    // because there is already an existing type, "Person".
    Console.WriteLine( "\t Type Name: {0}", typeName);

    if (typeName.Equals("PersonSurrogated") )
    {
        Console.WriteLine("Returning Person");
        return typeof(Person);
    }
    return null;
}

Public Function GetReferencedTypeOnImport(ByVal typeName As String, _
    ByVal typeNamespace As String, ByVal customData As Object) As Type _
    Implements IDataContractSurrogate.GetReferencedTypeOnImport
    Console.WriteLine("GetReferencedTypeOnImport invoked")
    ' This method is called on schema import.
    ' If a PersonSurrogated data contract is 
    ' in the specified namespace, do not create a new type for it 
    ' because there is already an existing type, "Person".
    Console.WriteLine(vbTab & "Type Name: {0}", typeName)

    'If typeNamespace.Equals("http://schemas.datacontract.org/2004/07/DCSurrogateSample") Then
    If typeName.Equals("PersonSurrogated") Then
        Console.WriteLine("Returning Person")
        Return GetType(Person)
    End If
    'End If
    Return Nothing

End Function

Null should be returned if a CLR type does not exist for representing the schema type. This will cause a new type to be generated during schema import.
