.NET Framework Class Library

NetworkCredential Class

Provides credentials for password-based authentication schemes such as basic, digest, NTLM, and Kerberos authentication.

Namespace: System.Net
Assembly: System (in System.dll)

Syntax

Visual Basic (Declaration)

Public Class NetworkCredential _
    Implements ICredentials, ICredentialsByHost

Visual Basic (Usage)

Dim instance As NetworkCredential

public class NetworkCredential : ICredentials, 
    ICredentialsByHost

Visual C++

public ref class NetworkCredential : ICredentials, 
    ICredentialsByHost

JScript

public class NetworkCredential implements ICredentials, ICredentialsByHost

Remarks

The NetworkCredential class is a base class that supplies credentials in password-based authentication schemes such as basic, digest, NTLM, and Kerberos. Classes that implement the ICredentials interface, such as the CredentialCache class, return NetworkCredential objects.

This class does not support public key-based authentication methods such as Secure Sockets Layer (SSL) client authentication.

Examples

The following code example associates a NetworkCredential object with a set of Uniform Resource Identifiers (URIs) in a CredentialCache. It then passes the CredentialCache to a WebRequest object, which uses it to authenticate requests to an Internet server.

Visual Basic

Dim myCred As New NetworkCredential(SecurelyStoredUserName,SecurelyStoredPassword,SecurelyStoredDomain )

Dim myCache As New CredentialCache()

myCache.Add(New Uri("www.contoso.com"), "Basic", myCred)
myCache.Add(New Uri("app.contoso.com"), "Basic", myCred)

Dim wr As WebRequest = WebRequest.Create("www.contoso.com")
wr.Credentials = myCache

NetworkCredential myCred = new NetworkCredential(
    SecurelyStoredUserName,SecurelyStoredPassword,SecurelyStoredDomain);

CredentialCache myCache = new CredentialCache();

myCache.Add(new Uri("www.contoso.com"), "Basic", myCred);
myCache.Add(new Uri("app.contoso.com"), "Basic", myCred);

WebRequest wr = WebRequest.Create("www.contoso.com");
wr.Credentials = myCache;

Visual C++

NetworkCredential^ myCred = gcnew NetworkCredential(
   SecurelyStoredUserName,SecurelyStoredPassword,SecurelyStoredDomain );

CredentialCache^ myCache = gcnew CredentialCache;

myCache->Add( gcnew Uri( "www.contoso.com" ), "Basic", myCred );
myCache->Add( gcnew Uri( "app.contoso.com" ), "Basic", myCred );

WebRequest^ wr = WebRequest::Create( "www.contoso.com" );
wr->Credentials = myCache;

JScript

 var myCred : NetworkCredential = new NetworkCredential(
    SecurelyStoredUserName, SecurelyStoredPassword, SecurelyStoredDomain )

 var myCache : CredentialCache = new CredentialCache()

 myCache.Add(new Uri("www.contoso.com"), "Basic", myCred)
 myCache.Add(new Uri("app.contoso.com"), "Basic", myCred)

 var wr : WebRequest = WebRequest.Create("www.contoso.com")
 wr.Credentials = myCache
