public enum HttpClientCredentialType

Member nameDescription
NoneSpecifies anonymous authentication.

DigestSpecifies Digest authentication. For more information, see RFC 2617 – HTTP Authentication: Basic and Digest Authentication.

This enumeration is used by ClientCredentialType to specify the type of client credential to be used for authentication.

Note that if SecurityMode is set to TransportWithMessageCredential, then the value of HttpClientCredentialType is ignored.

The following code shows how to set ClientCredentialType to a member of this enumeration.


// The code uses a shortcut to specify the security mode to Transport.
WSHttpBinding b = new WSHttpBinding(SecurityMode.Transport);
b.Security.Transport.ClientCredentialType = HttpClientCredentialType.Windows;
