Definisi

Ruang nama:
System.Web.ApplicationServices
Rakitan:
System.Web.Extensions.dll

public:
 static event EventHandler<System::Web::ApplicationServices::AuthenticatingEventArgs ^> ^ Authenticating;
public static event EventHandler<System.Web.ApplicationServices.AuthenticatingEventArgs> Authenticating;
member this.Authenticating : EventHandler<System.Web.ApplicationServices.AuthenticatingEventArgs> 
Public Shared Custom Event Authenticating As EventHandler(Of AuthenticatingEventArgs)

Jenis Acara

EventHandler<AuthenticatingEventArgs>

Contoh

Contoh berikut menunjukkan cara mengikat penanganan aktivitas untuk Authenticating peristiwa dalam Application_Start metode file 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

Contoh berikut menunjukkan penanganan aktivitas untuk Authenticating peristiwa dalam file Global.asax. Penanganan aktivitas membaca dua nilai autentikasi dari CustomCredential properti dan meneruskannya bersama dengan nama pengguna dan kata sandi ke kelas autentikasi kustom bernama 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
