CredentialCache.Add Method (Uri, String, NetworkCredential)

Adds a NetworkCredential instance to the credential cache for use with protocols other than SMTP and associates it with a Uniform Resource Identifier (URI) prefix and authentication protocol.

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

public void Add(
	Uri uriPrefix,
	string authType,
	NetworkCredential cred
)

Parameters

uriPrefix
Type: System.Uri

A Uri that specifies the URI prefix of the resources that the credential grants access to.

authType
Type: System.String

The authentication scheme used by the resource named in uriPrefix.

cred
Type: System.Net.NetworkCredential

The NetworkCredential to add to the credential cache.

ExceptionCondition
ArgumentNullException

uriPrefix is null.

-or-

authType is null.

ArgumentException

The same credentials are added more than once.

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.

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

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;
CredentialCache* myCache = new CredentialCache();

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

wReq->Credentials = myCache;
