ICustomAttributeProvider

Yang ICustomAttributeProvider mewakili atribut kustom dari jenis pengembalian untuk metode dinamis.

Contoh

Contoh kode berikut menunjukkan cara menampilkan atribut kustom dari jenis pengembalian metode dinamis. Contoh kode ini adalah bagian dari contoh yang lebih besar yang disediakan untuk DynamicMethod kelas .

// 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

Keterangan

Atribut kustom tidak didukung pada jenis pengembalian metode dinamis, sehingga array atribut kustom yang dikembalikan oleh GetCustomAttributes metode selalu kosong.
