Exemples

L’exemple de code suivant montre comment case activée la valeur de pour DesignerSerializationVisibilityAttributeMyProperty. Tout d’abord, le code obtient un PropertyDescriptorCollection avec toutes les propriétés de l’objet . Ensuite, le code s’indexe dans pour PropertyDescriptorCollection obtenir MyProperty. Ensuite, le code retourne les attributs de cette propriété et les enregistre dans la variable d’attributs.

Cet exemple présente deux méthodes différentes pour case activée la valeur de .DesignerSerializationVisibilityAttribute Dans le deuxième fragment de code, l’exemple appelle la Equals méthode avec une static valeur . Dans le dernier fragment de code, l’exemple utilise la Visibility propriété pour case activée la valeur.

// Gets the attributes for the property.
AttributeCollection^ attributes = TypeDescriptor::GetProperties( this )[ "MyProperty" ]->Attributes;

// Checks to see if the value of the DesignerSerializationVisibilityAttribute is set to Content.
if ( attributes[ DesignerSerializationVisibilityAttribute::typeid ]->Equals( DesignerSerializationVisibilityAttribute::Content ) )
{
   // Insert code here.
}


// This is another way to see whether the property is marked as serializing content.
DesignerSerializationVisibilityAttribute^ myAttribute = dynamic_cast<DesignerSerializationVisibilityAttribute^>(attributes[ DesignerSerializationVisibilityAttribute::typeid ]);
if ( myAttribute->Visibility == DesignerSerializationVisibility::Content )
{
   // Insert code here.
}

// Gets the attributes for the property.
 AttributeCollection attributes = 
    TypeDescriptor.GetProperties(this)["MyProperty"].Attributes;
 
 // Checks to see if the value of the DesignerSerializationVisibilityAttribute is set to Content.
 if(attributes[typeof(DesignerSerializationVisibilityAttribute)].Equals(DesignerSerializationVisibilityAttribute.Content)) {
    // Insert code here.
 }
 
 // This is another way to see whether the property is marked as serializing content.
 DesignerSerializationVisibilityAttribute myAttribute = 
    (DesignerSerializationVisibilityAttribute)attributes[typeof(DesignerSerializationVisibilityAttribute)];
 if(myAttribute.Visibility == DesignerSerializationVisibility.Content) {
    // Insert code here.
 }

' Gets the attributes for the property.
Dim attributes As AttributeCollection = _
    TypeDescriptor.GetProperties(Me)("MyProperty").Attributes

' Checks to see if the value of the DesignerSerializationVisibilityAttribute
' is set to Content.
If attributes(GetType(DesignerSerializationVisibilityAttribute)).Equals( _
    DesignerSerializationVisibilityAttribute.Content) Then
    ' Insert code here.
End If 

' This is another way to see whether the property is marked as serializing content.
Dim myAttribute As DesignerSerializationVisibilityAttribute = _
    CType(attributes(GetType(DesignerSerializationVisibilityAttribute)), _
    DesignerSerializationVisibilityAttribute)
If myAttribute.Visibility = DesignerSerializationVisibility.Content Then
    ' Insert code here.
End If
