问题 I'm new at using the the libraries WebClient, HttpResponse and HttpRequest in C#, so bear with me, if my question is confusing to read. I need to build a WinForm based on C# which can open a URL, which is secured with the basic authorization.

问题 I would like to know if I code it correctly. To upload file manually to my workplace server, I have to use Login ID and Password. With the clode below, should I include my loginID and Password as well? public void SaveLogsToWeb(string logFileName) { WebClient webClient = new WebClient(); string webAddress = null; try { webAddress = @"http://myCompany/ShareDoc/"; webClient.Credentials = CredentialCache.DefaultCredentials; WebRequest serverRequest = WebRequest.Create(webAddress); WebResponse

问题 I'm need to send a message using Twilio services and the NetDuino. I know there is an API that allows to send messages but it uses Rest-Sharp behind the scene which is not compatible with the micro-framework. I have try to do something like the below but I got a 401 error (not authorized). I got this code form here (which is exactly what I need to do) var MessageApiString = "https://api.twilio.com/2010-04-01/Accounts/{AccountSid}/SMS/Messages.json"; var request = WebRequest.Create

My code: public void start() { if (File.Exists("Data/version.txt")) { File.Delete
