Definición

Espacio de nombres:

System.ComponentModel

Ensamblado:

System.ComponentModel.Primitives.dll

Source:

DesignerSerializationVisibilityAttribute.cs

Obtiene un valor que indica el modo básico de serialización que debe utilizar un serializador al determinar si se conserva el valor de una propiedad y la forma de hacerlo.

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

Valor de propiedad

DesignerSerializationVisibility

Uno de los valores de DesignerSerializationVisibility. De manera predeterminada, es Visible.

Ejemplos

En el ejemplo de código siguiente se muestra cómo comprobar el valor de para DesignerSerializationVisibilityAttributeMyProperty. En primer lugar, el código obtiene con PropertyDescriptorCollection todas las propiedades del objeto . A continuación, el código indexa en para PropertyDescriptorCollection obtener MyProperty. A continuación, el código devuelve los atributos de esta propiedad y los guarda en la variable attributes.

En este ejemplo se presentan dos maneras diferentes de comprobar el valor de DesignerSerializationVisibilityAttribute. En el segundo fragmento de código, el ejemplo llama al Equals método con un static valor . En el último fragmento de código, en el ejemplo se usa la Visibility propiedad para comprobar el valor.

// 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
