public:
 void Add(Uri ^ uriPrefix, System::String ^ authType, System::Net::NetworkCredential ^ cred);

public void Add (Uri uriPrefix, string authType, System.Net.NetworkCredential cred);

member this.Add : Uri * string * System.Net.NetworkCredential -> unit

Examples

The following code example initializes a CredentialCache with multiple security credentials and uses those credentials with a WebRequest.

CredentialCache^ myCache = gcnew CredentialCache;

myCache->Add( gcnew Uri( "http://www.contoso.com/" ), "Basic", gcnew NetworkCredential( UserName,SecurelyStoredPassword ) );
myCache->Add( gcnew Uri( "http://www.contoso.com/" ), "Digest", gcnew NetworkCredential( UserName,SecurelyStoredPassword,Domain ) );

wReq->Credentials = myCache;

CredentialCache myCache = new CredentialCache();

myCache.Add(new Uri("http://www.contoso.com/"),"Basic",new NetworkCredential(UserName,SecurelyStoredPassword));
myCache.Add(new Uri("http://www.contoso.com/"),"Digest", new NetworkCredential(UserName,SecurelyStoredPassword,Domain));

wReq.Credentials = myCache;

Dim myCache As New CredentialCache()

myCache.Add(New Uri("http://www.contoso.com/"), "Basic", New NetworkCredential(UserName, SecurelyStoredPassword))
myCache.Add(New Uri("http://www.contoso.com/"), "Digest", New NetworkCredential(UserName, SecurelyStoredPassword, Domain))

wReq.Credentials = myCache

Remarks

The Add method places a NetworkCredential instance for use with protocols other than SMTP into the CredentialCache. The cache stores credentials in the order in which they are added to it. When the GetCredential(Uri, String) method is called, it returns the proper matching NetworkCredential instance.

Examples

The following code example initializes a CredentialCache with multiple security credentials for use with SMTP and uses one of those credentials with a SmtpClient.

SmtpClient^ client = gcnew SmtpClient("ContosoMail", 45);
MailAddress^ from = gcnew MailAddress("[email protected]", "Sender Name");
MailAddress^ to = gcnew MailAddress("[email protected]", "Recepient Name");
MailMessage^ message = gcnew MailMessage(from, to);

message->Body = "This is a test email message sent by an application. ";
message->Subject = "Test Email using Credentials";

NetworkCredential^ myCreds = gcnew NetworkCredential("username", "password", "domain");
CredentialCache^ myCredentialCache = gcnew CredentialCache();        
try 
{
    myCredentialCache->Add("ContoscoMail", 35, "Basic", myCreds);
    myCredentialCache->Add("ContoscoMail", 45, "NTLM", myCreds);
            
    client->Credentials = myCredentialCache->GetCredential("ContosoMail", 45, "NTLM");
    client->Send(message);
    Console::WriteLine("Goodbye.");
}
    catch(Exception^ e)
    {
          Console::WriteLine("Exception is raised. ");
          Console::WriteLine("Message: {0} ",e->Message);
    }

SmtpClient client = new SmtpClient("ContosoMail", 45);
MailAddress from = new MailAddress("[email protected]", "Sender Name");
MailAddress to = new MailAddress("[email protected]", "Recepient Name");
MailMessage message = new MailMessage(from, to);

message.Body = "This is a test email message sent by an application. ";
message.Subject = "Test Email using Credentials";

NetworkCredential myCreds = new NetworkCredential("username", "password", "domain");
CredentialCache myCredentialCache = new CredentialCache();
try
{
    myCredentialCache.Add("ContoscoMail", 35, "Basic", myCreds);
    myCredentialCache.Add("ContoscoMail", 45, "NTLM", myCreds);

    client.Credentials = myCredentialCache.GetCredential("ContosoMail", 45, "NTLM");
    client.Send(message);
    Console.WriteLine("Goodbye.");
}
    catch(Exception e)
    {
          Console.WriteLine("Exception is raised. ");
          Console.WriteLine("Message: {0} ",e.Message);
    }

    myCredentialCache.Add("ContoscoMail", 45, "NTLM", myCreds)

    client.Credentials = myCredentialCache.GetCredential("ContosoMail", 45, "NTLM")
    client.Send(message)
    Console.WriteLine("Goodbye.")
Catch e As Exception
    Console.WriteLine("Exception is raised. ")
    Console.WriteLine($"Message: {e.Message} ")
End Try

Remarks

This method places a NetworkCredential instance for use with SMTP into the CredentialCache. The cache stores credentials in the order in which they are added to it. When the GetCredential(String, Int32, String) method is called, it returns a NetworkCredential instance that is selected by matching the host, port, and authType. The comparison is done case-insensitively.

The supported values for authType are "NTLM", "Digest", "Kerberos", and "Negotiate".

Credentials added with this method are only valid for use with SMTP. This method does not work for HTTP or FTP protocols.
