Credentials Property

FtpWebRequest.Credentials Property

Note: This property is new in the .NET Framework version 2.0.

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

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

Public Overrides Property Credentials As ICredentials
Dim instance As FtpWebRequest
Dim value As ICredentials

value = instance.Credentials

instance.Credentials = value
/** @property */
public ICredentials get_Credentials ()

/** @property */
public void set_Credentials (ICredentials value)

public override function get Credentials () : ICredentials

public override function set Credentials (value : ICredentials)

Property Value

An ICredentials instance; otherwise, a null reference (Nothing in Visual Basic) if the property has not been set.

Exception typeCondition


The value specified for a set operation is a null reference (Nothing in Visual Basic).


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.

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}",
