Exemples

L’exemple suivant est conçu pour une utilisation avec Windows Forms et nécessite PaintEventArgse, qui est un paramètre du gestionnaire d’événements Paint. Le code effectue les actions suivantes :

• Convertit un objet StringFormat en chaîne.

• Dessine la chaîne.

• Modifie certaines propriétés dans l’objet StringFormat.

• Dessine la chaîne. La chaîne sera différente, car les propriétés de l’objet StringFormat ont changé.

void ToStringExample( PaintEventArgs^ e )

   StringFormat^ myStringFormat = gcnew StringFormat;

   // String variable to hold the values of the StringFormat object.
   String^ strFmtString;

   // Convert the string format object to a string (only certain information
   // in the object is converted) and display the string.
   strFmtString = myStringFormat->ToString();
   g->DrawString( String::Format( "Before changing properties:   {0}", myStringFormat ), myFont, blueBrush, 20, 40 );

   // Change some properties of the string format
   myStringFormat->Trimming = StringTrimming::None;

   // Convert the string format object to a string and display the string.
   // The string will be different because the properties of the string

Seule la valeur de la propriété FormatFlags est convertie.
