ICustomAttributeProvider représentant les attributs personnalisés du type de retour pour la méthode dynamique.
Exemples
L’exemple de code suivant montre comment afficher les attributs personnalisés du type de retour d’une méthode dynamique. Cet exemple de code fait partie d’un exemple plus grand fourni pour la DynamicMethod classe .
// 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
Remarques
Les attributs personnalisés ne sont pas pris en charge sur le type de retour d’une méthode dynamique, de sorte que le tableau d’attributs personnalisés retourné par la GetCustomAttributes méthode est toujours vide.
