WebClient.UseDefaultCredentials Property

Definition

Namespace:

System.Net

Assemblies:

netstandard.dll, System.Net.WebClient.dll

Source:

WebClient.cs

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

C#

public bool UseDefaultCredentials { get; set; }

Property Value

Boolean

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

Examples

The following code example demonstrates setting this property.

C#

// Sample call: UploadFileInBackground3("http://www.contoso.com/fileUpload.aspx", "data.txt")
public static void UploadFileInBackground3(string address, string fileName)
{
    WebClient client = new WebClient();

    Uri uri = new Uri(address);

    client.UseDefaultCredentials = true;
    client.UploadFileCompleted += new UploadFileCompletedEventHandler(UploadFileCallback2);
    client.UploadFileAsync(uri, fileName);
    Console.WriteLine("File upload started.");
}

Remarks

Caution

WebRequest, HttpWebRequest, ServicePoint, and WebClient are obsolete, and you shouldn't use them for new development. Use HttpClient instead.

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.
