ICustomAttributeProvider

Reprezentująca ICustomAttributeProvider atrybuty niestandardowe typu zwracanego dla metody dynamicznej.

Przykłady

Poniższy przykład kodu przedstawia sposób wyświetlania atrybutów niestandardowych zwracanego typu metody dynamicznej. Ten przykład kodu jest częścią większego przykładu podanego DynamicMethod dla klasy.

// ReturnTypeCustomAttributes returns an ICustomeAttributeProvider
// that can be used to enumerate the custom attributes of the
// return value. At present, there is no way to set such custom
// attributes, so the list is empty.
if (hello->ReturnType == Void::typeid)
{
    Console::WriteLine("The method has no return type.");
}
else
{
    ICustomAttributeProvider^ caProvider = hello->ReturnTypeCustomAttributes;
    array<Object^>^ returnAttributes = caProvider->GetCustomAttributes(true);
    if (returnAttributes->Length == 0)
    {
        Console::WriteLine("\r\nThe return type has no custom attributes.");
    }
    else
    {
        Console::WriteLine("\r\nThe return type has the following custom attributes:");
        for each (Object^ attr in returnAttributes)
        {
            Console::WriteLine("\t{0}", attr->ToString());
        }
    }
}

// ReturnTypeCustomAttributes returns an ICustomeAttributeProvider
// that can be used to enumerate the custom attributes of the
// return value. At present, there is no way to set such custom
// attributes, so the list is empty.
if (hello.ReturnType == typeof(void))
{
    Console.WriteLine("The method has no return type.");
}
else
{
    ICustomAttributeProvider caProvider = hello.ReturnTypeCustomAttributes;
    object[] returnAttributes = caProvider.GetCustomAttributes(true);
    if (returnAttributes.Length == 0)
    {
        Console.WriteLine("\r\nThe return type has no custom attributes.");
    }
    else
    {
        Console.WriteLine("\r\nThe return type has the following custom attributes:");
        foreach( object attr in returnAttributes )
        {
            Console.WriteLine("\t{0}", attr.ToString());
        }
    }
}

' ReturnTypeCustomAttributes returns an ICustomeAttributeProvider
' that can be used to enumerate the custom attributes of the
' return value. At present, there is no way to set such custom
' attributes, so the list is empty.
If hello.ReturnType Is GetType(System.Void) Then
    Console.WriteLine("The method has no return type.")
Else
    Dim caProvider As ICustomAttributeProvider = _
        hello.ReturnTypeCustomAttributes
    Dim returnAttributes() As Object = _
        caProvider.GetCustomAttributes(True)
    If returnAttributes.Length = 0 Then
        Console.WriteLine(vbCrLf _
            & "The return type has no custom attributes.")
    Else
        Console.WriteLine(vbCrLf _
            & "The return type has the following custom attributes:")
        For Each attr As Object In returnAttributes
            Console.WriteLine(vbTab & attr.ToString())
        Next attr
    End If
End If

Uwagi

Atrybuty niestandardowe nie są obsługiwane w przypadku zwracanego typu metody dynamicznej, więc tablica atrybutów niestandardowych zwracanych przez GetCustomAttributes metodę jest zawsze pusta.
