SectionInformation.ForceSave Property

Gets or sets a value that indicates whether the associated configuration section will be saved even if it has not been modified.

Namespace:  System.Configuration
Assembly:  System.Configuration (in System.Configuration.dll)

public bool ForceSave { get; set; }

Property Value

Type: System.Boolean
true if the associated ConfigurationSection object will be saved even if it has not been modified; otherwise, false. The default is false.

If the configuration file is saved (even if there are no modifications), ASP.NET restarts the application.

The following example shows how to use the ForceSave property of a ConfigurationSection object.

// Create a section whose name is 
// MyUrls that contains a nested collection as 
// defined by the UrlsSection class.
static void CreateSection()
    string sectionName = "MyUrls";


        // Get the current configuration file.
        System.Configuration.Configuration config =

        UrlsSection urlsSection;

        // Create the section whose name attribute 
        // is MyUrls in <configSections>.
        // Also, create the related target section 
        // MyUrls in <configuration>.
        if (config.Sections[sectionName] == null)
            urlsSection = new UrlsSection();

            // Change the default values of 
            // the simple element.
            urlsSection.Simple.Name = "Contoso";
            urlsSection.Simple.Url = "";
            urlsSection.Simple.Port = 8080;

            config.Sections.Add(sectionName, urlsSection);
            urlsSection.SectionInformation.ForceSave = true;
    catch (ConfigurationErrorsException e)
        Console.WriteLine("[CreateSection: {0}]",
