如何使用Webclient捕获任何错误？
|
我正在尝试使用WebClient捕获连接问题。例如，无法访问，超时等。下面的代码不起作用，好像没有错误。
WebClient wc = new WebClient();
try
{
wc.UploadFileAsync(new Uri(@\"ftp://tabletijam/FileServer/upload.bin\"), Directory.GetCurrentDirectory() + @\"\\crypto.bin\");
}
catch (System.Exception ex)
{
MessageBox.Show(ex.ToString());
}
没有找到相关结果

WebClient webClient = new WebClient(); webClient.UploadFileAsync(address, fileName); webClient.UploadProgressChanged += WebClientUploadProgressChanged; webClient.UploadFileCompleted += WebClientUploadCompleted; ... void WebClientUploadProgressChanged(object sender, UploadProgressChangedEventArgs e) { Console.WriteLine(\"Download {0}% complete. \", e.ProgressPercentage); } void WebClientUploadCompleted(object sender, UploadFileCompletedEventArgs e) { // The upload is finished, clean up }泪琉踞檄
try { // trying to make any operation on a file } catch (IOException error) { if(error is FileNotFoundException) { // Handle this error } }
