XmlResolver.Credentials Property

When overridden in a derived class, sets the credentials used to authenticate Web requests.

[Visual Basic]
Property Credentials As ICredentials
ICredentials Credentials {set;}
public: __property virtual void set_Credentials(ICredentials*) = 0;
public abstract function set Credentials(ICredentials);

Property Value

An ICredentials object. If this property is not set, the value defaults to a null reference (Nothing in Visual Basic); that is, the XmlResolver has no user credentials.


If the virtual directory does not require authentication, this property does not need to be set. Otherwise, the credentials of the user must be supplied.

The following C# code sets credentials for the virtual directory "http://localhost/bookstore/inventory.xml"

XmlTextReader reader = new XmlTextReader("http://localhost/bookstore/inventory.xml");
NetworkCredential nc = new NetWorkCredential(UserName,SecurelyStoredPassword,Domain);
XmlUrlResolver resolver = new XmlUrlResolver();
resolver.Credentials = nc;
reader.XmlResolver= resolver;

Different credentials can be associated with different URIs, and added to a credential cache. The credentials can then be used to check authentication for different URIs regardless of the original source of the XML.

NetworkCredential myCred = new NetworkCredential(UserName,SecurelyStoredPassword,Domain); 
CredentialCache myCache = new CredentialCache(); 
myCache.Add(new Uri(""), "Basic", myCred); 
myCache.Add(new Uri(""), "Basic", myCred);
XmlUrlResolver resolver = new XmlUrlResolver();
resolver.Credentials = myCache;
reader.XmlResolver = resolver;


See XmlUrlResolver.Credentials for an example using this property.
