我有一个C＃应用程序，它可以作为更新程序 . 该程序检查互联网上的文件是否有当前版本，如果该版本大于已安装的版本，它将继续使用URL和webclient从网站下载可执行文件（而不是.zip） . 相关守则（减号个人信息/网址）：
Main Thread:
string webUrl = @"http://mywebsite/executable" + NewVersion + ".exe";
Thread thread = new Thread(() => {
try
{
WebClient updateDownloader = new WebClient();
Uri newExecutable = new Uri(webUrl);
updateDownloader.DownloadProgressChanged += new DownloadProgressChangedEventHandler(client_DownloadProgressChanged);
updateDownloader.DownloadFileCompleted += new AsyncCompletedEventHandler(client_DownloadFileCompleted);
updateDownloader.DownloadFileAsync(newExecutable, @"C:\Users\Public\MyExecutable.exe");
}
catch(Exception WebError) { MessageBox.Show(WebError.ToString()); }
});
button1.Enabled = false;
thread.Start();
Download Progress Changed Event:
void client_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
{
this.BeginInvoke((MethodInvoker)delegate {
double bytesIn = double.Parse(e.BytesReceived.ToString());
double totalBytes = double.Parse(e.TotalBytesToReceive.ToString());
double percentage = bytesIn / totalBytes * 100;
label1.Text = "Downloaded " + (e.BytesReceived * .001) + "KB of " + (e.TotalBytesToReceive * .001)+"KB";
progressBar1.Style = ProgressBarStyle.Blocks;
progressBar1.Value = int.Parse(Math.Truncate(percentage).ToString());
if(progressBar1.Value == 100)
{
label1.Text = "100%";
}
});
}
Download Completed Event:
void client_DownloadFileCompleted(object sender, AsyncCompletedEventArgs e)
{
this.BeginInvoke((MethodInvoker)delegate {
label2.Text = "Completed";
button1.Enabled = true;
MessageBox.Show("Download Complete! Press OK to launch the new version.", "Download Complete", MessageBoxButtons.OK, MessageBoxIcon.Information);
try
{
Process.Start(@"C:\Users\Public\MyExecutable.exe");
}
catch(Exception ee) { MessageBox.Show("Error: " + ee.ToString()); }
Application.Exit();
});
}
My Issue Is: 应用程序将下载几乎整个文件，但将在结束时停止（参见图像） . 这使得可执行文件无法运行（也见图像） .
我尝试使用Chrome和Firefox下载相同的文件，90％的时间它可以正常工作 . 另外10％的时间它会识别要下载的文件，但永远不会从 0 bytes/0 bytes 进展 .
在不同的PC上运行相同的应用程序工作正常 . 防火墙未配置为阻止此应用程序或任何下载，并且它无法启用或禁用Windows智能屏幕 . （管理员权限和兼容模式也是如此）
一个星期前，最奇怪的部分是在同一台机器上使用相同的程序工作得很好 .
TL;DR ：我的计划赢了't download a file without it being corrupted, while from a web browser it [usually] works just fine. This same program works fine on every other PC I'试了 .
任何帮助将不胜感激，包括代码更改建议，以及手头问题的可能解决方案 .
Update 我让程序运行，直到它应该已经完成下载文件 . 这是具体的错误：
