Exemplos

O exemplo de código a seguir usa o GetCredential método para recuperar um NetworkCredential objeto para o URI especificado.

// Create an empty instance of the NetworkCredential class.
NetworkCredential^ myCredentials = gcnew NetworkCredential( userName,password );

// Create a webrequest with the specified URL.
WebRequest^ myWebRequest = WebRequest::Create( url );
myWebRequest->Credentials = myCredentials->GetCredential( gcnew Uri( url ), "" );
Console::WriteLine( "\n\nUser Credentials:- UserName : {0} , Password : {1}",
   myCredentials->UserName, myCredentials->Password );

// Send the request and wait for a response.
Console::WriteLine( "\n\nRequest to Url is sent.Waiting for response...Please wait ..." );
WebResponse^ myWebResponse = myWebRequest->GetResponse();

// Process the response.
Console::WriteLine( "\nResponse received successfully" );

// Release the resources of the response object.
myWebResponse->Close();

// Create an empty instance of the NetworkCredential class.
NetworkCredential myCredentials = new NetworkCredential(userName,password);
// Create a webrequest with the specified URL.
WebRequest myWebRequest = WebRequest.Create(url);
myWebRequest.Credentials = myCredentials.GetCredential(new Uri(url),"");
Console.WriteLine("\n\nUser Credentials:- UserName : {0} , Password : {1}",myCredentials.UserName,myCredentials.Password);
// Send the request and wait for a response.
Console.WriteLine("\n\nRequest to Url is sent.Waiting for response...Please wait ...");
WebResponse myWebResponse = myWebRequest.GetResponse();
// Process the response.
   Console.WriteLine("\nResponse received successfully");
// Release the resources of the response object.
myWebResponse.Close();

' Create an empty instance of the NetworkCredential class.
Dim myCredentials As New NetworkCredential(userName, password)
' Create a WebRequest with the specified URL. 
Dim myWebRequest As WebRequest = WebRequest.Create(url)
' GetCredential returns the same NetworkCredential instance that invoked it, 
' irrespective of what parameters were provided to it. 
 myWebRequest.Credentials = myCredentials.GetCredential(New Uri(url), "")
Console.WriteLine(ControlChars.Cr + ControlChars.Cr + "User Credentials:- UserName : {0} , Password : {1}", myCredentials.UserName, myCredentials.Password)
' Send the request and wait for a response.
Console.WriteLine(ControlChars.Cr + ControlChars.Cr + "Request to Url is sent.Waiting for response...Please wait ...")
Dim myWebResponse As WebResponse = myWebRequest.GetResponse()
' Process the response.
Console.WriteLine(ControlChars.Cr + "Response received successfully")
' Release the resources of the response object.
myWebResponse.Close()
