Příklady

Následující příklad kódu ukazuje, jak zkontrolovat hodnotu DesignerSerializationVisibilityAttribute pro MyProperty. Nejprve kód získá objekt se PropertyDescriptorCollection všemi vlastnostmi objektu. Dále se kód indexuje do objektu , PropertyDescriptorCollection aby získal MyProperty. Pak kód vrátí atributy pro tuto vlastnost a uloží je do proměnné atributů.

Tento příklad představuje dva různé způsoby kontroly hodnoty DesignerSerializationVisibilityAttribute. V druhém fragmentu kódu volá příklad metodu Equals s static hodnotou. V posledním fragmentu kódu používá příklad Visibility vlastnost ke kontrole hodnoty.

// 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
