WebClient Constructor ()


Initializes a new instance of the WebClient class.

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


The default constructor creates a new instance of the WebClient class. The default HTTP method is GET. The default FTP method is RETR. The default Encoding is Default. The default value of AllowAutoRedirect is true.

The following code example creates a WebClient instance and then uses it to download data from a server and display it on the system console, to download data from a server and write it to a file, and to upload form values to a server and receive the response.

   // Download the data to a buffer.
   WebClient^ client = gcnew WebClient;

   array<Byte>^ pageData = client->DownloadData( "http://www.contoso.com" );
   String^ pageHtml = Encoding::ASCII->GetString( pageData );
   Console::WriteLine( pageHtml );

   // Download the data to a file.
   client->DownloadFile( "http://www.contoso.com", "page.htm" );

   // Upload some form post values.
   NameValueCollection^ form = gcnew NameValueCollection;
   form->Add( "MyName", "MyValue" );
   array<Byte>^ responseData = client->UploadValues( "http://www.contoso.com/form.aspx", form );
catch ( WebException^ webEx ) 
   Console::WriteLine( webEx->ToString() );
   if ( webEx->Status == WebExceptionStatus::ConnectFailure )
      Console::WriteLine( "Are you behind a firewall?  If so, go through the proxy server." );
