问题 I want to read a file from a FTP server without downloading it to a local file. I wrote a function but it does not work: private string GetServerVersion() { WebClient request = new WebClient(); string url = FtpPath + FileName; string version = ""; request.Credentials = new NetworkCredential(ftp_user, ftp_pas); try { byte[] newFileData = request.DownloadData(new Uri(FtpPath)+FileName); string fileString = System.Text.Encoding.UTF8.GetString(newFileData); } catch (WebException e) { } return

问题 I have one. aspx page that has some JavaScript functions that control paging. I can run this javascript function via webbrowser with the following method within the WebBrowser1_DocumentCompleted WebBrowser1.Document.Window.DomWindow.execscript ("somefunction();", "JavaScript") The webbrowser is very slow and I prefer to use System.Net.WebClient.DownloadString .
