Nell'esempio seguente viene illustrato come utilizzare il metodo IsReadOnly.The following example shows how to use the IsReadOnly method. Viene usata in una sezione personalizzata e restituisce false.It is used on a custom section and returns false.

// Show how to use IsReadOnly.
// It loops to see if the elements are read only. 
static void ReadOnlyElements()
{
    try
    {

            ConfigurationManager.OpenExeConfiguration(
            ConfigurationUserLevel.None);

        // Get the MyUrls section.

Commenti

Il sistema definisce elementi di configurazione che non possono essere modificati.The system defines configuration elements that cannot be modified.

Per determinare quali elementi possono essere modificati, usare il IsReadOnly (metodo).To determine which elements can be modified, use the IsReadOnly method.
