Tipo de evento

Ejemplos

En el ejemplo siguiente se muestra cómo enlazar un controlador de eventos para el Authenticating evento en el Application_Start método del archivo Global.asax.

void Application_Start(object sender, EventArgs e) 
{
    System.Web.ApplicationServices.AuthenticationService.Authenticating += 
        new EventHandler<System.Web.ApplicationServices.AuthenticatingEventArgs>(AuthenticationService_Authenticating);

}

Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs)
    AddHandler System.Web.ApplicationServices.AuthenticationService.Authenticating, _
      AddressOf Me.AuthenticationService_Authenticating
End Sub

En el ejemplo siguiente se muestra un controlador de eventos para el Authenticating evento en el archivo Global.asax. El controlador de eventos lee dos valores de autenticación de la CustomCredential propiedad y los pasa junto con el nombre de usuario y la contraseña a una clase de autenticación personalizada denominada StudentAuthentication.

void AuthenticationService_Authenticating(object sender, System.Web.ApplicationServices.AuthenticatingEventArgs e)
{
    string studentid = String.Empty;
    string answer = String.Empty;

    string[] credentials =
        e.CustomCredential.Split(new char[] { ',' });
    if (credentials.Length > 0)
    {
        studentid = credentials[0];
        if (credentials.Length > 1)
        {
            answer = credentials[1];
        }
    }

    try
    {
        e.Authenticated =
            StudentAuthentication.ValidateStudentCredentials
            (e.UserName, e.Password, studentid, answer);
    }
    catch (ArgumentNullException ex)
    {
        e.Authenticated = false;
    }

    e.AuthenticationIsComplete = true;
}

Sub AuthenticationService_Authenticating _
   (ByVal sender As Object, _
    ByVal e As System.Web.ApplicationServices.AuthenticatingEventArgs)
    Dim studentid As String = String.Empty
    Dim answer As String = String.Empty

    Dim credentials As String() = _
         e.CustomCredential.Split(New Char() {","c})
    If (credentials.Length > 0) Then
        studentid = credentials(0)
        If (credentials.Length > 1) Then
            answer = credentials(1)
        End If
    End If

    Try
        e.Authenticated = _
            StudentAuthentication.ValidateStudentCredentials _
            (e.Username, e.Password, studentid, answer)
    Catch ex As ArgumentNullException
        e.Authenticated = False
    End Try
    

    e.AuthenticationIsComplete = True
End Sub

Comentarios

El Authenticating evento se genera cuando se validan las credenciales de usuario. Cree un controlador de eventos para el Authenticating evento para personalizar cómo se validan las credenciales de usuario.
