Obtient un tableau de chaînes contenant toutes les clés (noms de modules) dans la HttpModuleCollection.

public:
 property cli::array <System::String ^> ^ AllKeys { cli::array <System::String ^> ^ get(); };
public string[] AllKeys { get; }

String[]

Tableau de noms de modules.

Exemples

L’exemple de code suivant illustre la AllKeys propriété et les GetKey CopyTo méthodes de la HttpModuleCollection classe. L’exemple obtient l’objet d’application pour la requête actuelle de l’objet actuel HttpContext . Il extrait ensuite l’objet HttpModuleCollection de l’instance de l’application et affiche les noms des IHttpModule objets.

<%@ Page language="C#" %>
<%@ Import Namespace = "System.Data"  %>
<script runat="server">
// System.Web.HttpModuleCollection.AllKeys;GetKey;CopyTo

void Page_Load(object sender, System.EventArgs e)
{
    // Get the HttpContext object for the current request.
    HttpContext myHttpContext = HttpContext.Current;
    // Get the application object for the current request.
    HttpApplication myHttpApplication = myHttpContext.ApplicationInstance;
    // Get the collection of all HTTPModule objects for the current application.
    HttpModuleCollection myHttpModuleCollection = myHttpApplication.Modules;

    // Get the name of the HttpModule object at index 1.
    string httpModuleName = myHttpModuleCollection.GetKey(1);
    Response.Write("The name of the HttpModule object at index 1" + " is " +"'"+  httpModuleName+"'." + "<br><br>"); 

    string[] allModules = myHttpModuleCollection.AllKeys;

    // Display the names of all HttpModule objects.
    Response.Write("<b>The HttpModule objects contained in the HttpModuleCollection are:</b><br>");

    for(int i=0; i < allModules.Length; i++)
       Response.Write("Module" + i + "  : " + allModules[i] + "<br>");

    // Copy the HttpModule objects in the collection into an array.
    System.Array httpModuleArray = Array.CreateInstance(typeof(object),myHttpModuleCollection.AllKeys.Length);
    myHttpModuleCollection.CopyTo(httpModuleArray,0);
    Response.Write("<br><br><b>Successfully copied the HttpModule objects in the HttpModuleCollection to an array."+
       "<br>Displaying the HttpModule objects in array:</b><br>");

    for(int i=0; i < httpModuleArray.Length; i++)
       Response.Write("Module" + i + ": " + httpModuleArray.GetValue(i) + "<br>");
