Obtient une valeur indiquant le mode de sérialisation de base qu’un sérialiseur doit utiliser pour déterminer si et comment conserver la valeur d’une propriété.

public:
 property System::ComponentModel::DesignerSerializationVisibility Visibility { System::ComponentModel::DesignerSerializationVisibility get(); };

public System.ComponentModel.DesignerSerializationVisibility Visibility { get; }

member this.Visibility : System.ComponentModel.DesignerSerializationVisibility

Public ReadOnly Property Visibility As DesignerSerializationVisibility

Valeur de propriété

DesignerSerializationVisibility

Une des DesignerSerializationVisibility valeurs. La valeur par défaut est Visible.

Exemples

L’exemple de code suivant montre comment vérifier la valeur de la DesignerSerializationVisibilityAttribute valeur pour MyProperty. Tout d’abord, le code obtient une PropertyDescriptorCollection valeur avec toutes les propriétés de l’objet. Ensuite, le code indexe dans l’obtention PropertyDescriptorCollectionMyProperty. Ensuite, le code retourne les attributs de cette propriété et les enregistre dans la variable d’attributs.

Cet exemple présente deux façons différentes de vérifier la valeur du 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 vérifier 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
