WebClient.UseDefaultCredentials Property

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

Gets or sets a Boolean value that controls whether the DefaultCredentials are sent with requests.

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

'Declaration
Public Property UseDefaultCredentials As Boolean
'Usage
Dim instance As WebClient
Dim value As Boolean

value = instance.UseDefaultCredentials

instance.UseDefaultCredentials = value
/** @property */
public boolean get_UseDefaultCredentials ()

/** @property */
public void set_UseDefaultCredentials (boolean value)

public function get UseDefaultCredentials () : boolean

public function set UseDefaultCredentials (value : boolean)

Property Value

true if the default credentials are used; otherwise false. The default value is false.

Set this property to true when requests made by this WebClient object should, if requested by the server, be authenticated using the default credentials of the currently logged on user. For client applications, this is the desired behavior in most scenarios. For middle tier applications, such as ASP.NET applications, instead of using this property, you would typically set the Credentials property to the credentials of the client on whose behalf the request is made.

The following code example demonstrates setting this property.

'  Sample call: UploadFileInBackground3("http:' www.contoso.com/fileUpload.aspx", "data.txt")
Public Shared Sub UploadFileInBackground3(ByVal address As String, ByVal fileName As String)

    Dim client As WebClient = New WebClient()
                Dim uri as Uri =  New Uri(address)
    client.UseDefaultCredentials = True
    AddHandler client.UploadFileCompleted, AddressOf UploadFileCallback2
    client.UploadFileAsync(uri, fileName)
    Console.WriteLine("File upload started.")
End Sub
