Gets an object used to obtain identity, authentication information, and security roles for the client whose request is represented by this HttpListenerContext object.
public:
property System::Security::Principal::IPrincipal ^ User { System::Security::Principal::IPrincipal ^ get(); };
public System.Security.Principal.IPrincipal? User { get; }
public System.Security.Principal.IPrincipal User { get; }
member this.User : System.Security.Principal.IPrincipal
Public ReadOnly Property User As IPrincipal
Property Value
An IPrincipal object that describes the client, or null
if the HttpListener that supplied this HttpListenerContext does not require authentication.
Examples
The following code example demonstrates accessing identity and authentication information about the client, and returning it to the client in the response.
public static string ClientInformation(HttpListenerContext context)
{
System.Security.Principal.IPrincipal user = context.User;
System.Security.Principal.IIdentity id = user.Identity;
if (id == null)
{
return "Client authentication is not enabled for this Web server.";
}
string display;
if (id.IsAuthenticated)
{
display = String.Format("{0} was authenticated using {1}", id.Name,
id.AuthenticationType);
}
else
{
display = String.Format("{0} was not authenticated", id.Name);
}
return display;
}
Public Shared Function ClientInformation(ByVal context As HttpListenerContext) As String
Dim user As System.Security.Principal.IPrincipal = context.User
Dim id As System.Security.Principal.IIdentity = user.Identity
If id Is Nothing Then
Return "Client authentication is not enabled for this Web server."
End If
Dim display As String
If id.IsAuthenticated Then
display = String.Format("{0} was authenticated using {1}", id.Name, id.AuthenticationType)
Else
display = String.Format("{0} was not authenticated", id.Name)
End If
Return display
End Function
Remarks
An HttpListener indicates that it requires authentication using the AuthenticationSchemes property or by specifying an AuthenticationSchemeSelector delegate using the AuthenticationSchemeSelectorDelegate property.
To determine the client's login name and authentication information, check the IPrincipal.Identity property in the object returned by this property.
