Property Credentials As ICredentials
'Usage
Dim instance As IWebProxy
Dim value As ICredentials

value = instance.Credentials

instance.Credentials = value

ICredentials Credentials { get; set; }

property ICredentials^ Credentials {
    ICredentials^ get ();
    void set (ICredentials^ value);

Eigenschaftenwert

Eine ICredentials-Instanz, die die zum Authentifizieren einer Anforderung beim Proxyserver erforderlichen Anmeldeinformationen enthält.

Hinweise

Die Credentials-Eigenschaft ist eine ICredentials-Instanz, die die Anmeldeinformationen für die Authentifizierung enthält, die als Antwort auf den Statuscode HTTP 407 (Proxyautorisierung) an den Proxyserver gesendet werden sollen.

Beispiel

Im folgenden Beispiel wird die Credentials-Eigenschaft auf die Anmeldeinformationen festgelegt, die bei der Authentifizierung an den Proxyserver gesendet werden.
