HttpClientCredentialType Enumeration

Enumerates the valid credential types for HTTP clients.

Namespace:  System.ServiceModel
Assembly:  System.ServiceModel (in System.ServiceModel.dll)
public enum HttpClientCredentialType
Member name Description
None Specifies anonymous authentication.
Basic Specifies Basic authentication. For more information, see RFC 2617 – HTTP Authentication: Basic and Digest Authentication.
Digest Specifies Digest authentication. For more information, see RFC 2617 – HTTP Authentication: Basic and Digest Authentication.
Ntlm Specifies client authentication using NTLM.
Windows Specifies client authentication using Windows.
Certificate Specifies client authentication using a certificate.

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;
