FtpWebRequest.Credentials Property

Gets or sets the credentials used to communicate with the FTP server.

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.

ExceptionCondition
ArgumentNullException

The value specified for a set operation is null.

ArgumentException

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

InvalidOperationException

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.

Caution noteCaution

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}", 
    request.Credentials.GetCredential(request.RequestUri,"basic").UserName,
    request.RequestUri
);
