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

public override ICredentials Credentials { get; set; }

Property Value

Type: System.Net.ICredentials

An ICredentials instance; otherwise, null if the property has not been set.

Exception Condition

The value specified for a set operation is null.


An ICredentials of a type other than NetworkCredential was specified for a set operation.


A new value was specified for this property for a request that is already in progress.

You are not required to specify credentials when connecting using anonymous logon. You must set the Credentials property by using a credential of type NetworkCredential; this ensures that the user name and password can be read and sent to the server.


Credentials information is not encrypted when transmitted to the server unless the EnableSsl property is set to true.

Changing Credentials after calling the GetRequestStream, BeginGetRequestStream, GetResponse, or BeginGetResponse method causes an InvalidOperationException exception.

The following code example retrieves the value of this property and uses it to display the user name.

Console.WriteLine("User {0} {1}",
