Gets the authentication name for the user.

Namespace:   System.Web.ApplicationServices
Assembly:  System.Web.Extensions (in System.Web.Extensions.dll)

Public ReadOnly Property UserName As String

Property Value

Type: System.String

The user name to validate.

You use the UserName property to retrieve the authentication name during the Authenticating event.

The following example shows an event handler that selects a membership provider to use based on the value of the UserName property. The handler passes UserName and Password values to the custom membership provider to validate the user credentials. It sets Authenticated to the return value of the ValidateUser method and sets AuthenticationIsComplete to true so that the AuthenticationService class does not validate the credentials.

Sub AuthenticationService_Authenticating _
   (ByVal sender As Object, _
    ByVal e As System.Web.ApplicationServices.AuthenticatingEventArgs)

    If (e.Username.IndexOf("@contoso.com") >= 0) Then
        e.Authenticated = Membership.Providers("ContosoSqlProvider").ValidateUser(e.Username, e.Password)
    ElseIf (e.Username.IndexOf("@fabrikam.com") >= 0) Then
        e.Authenticated = Membership.Providers("FabrikamSqlProvider").ValidateUser(e.Username, e.Password)
    Else
        e.Authenticated = Membership.Provider.ValidateUser(e.Username, e.Password)
    End If
    e.AuthenticationIsComplete = True
End Sub
