C# 如何从Windows服务运行控制台应用程序？
我有一个用c#编写的windows服务，我需要从中运行控制台应用程序。 控制台应用程序也是用c#编写的 控制台应用程序在非从windows服务运行时运行正常。当它从ws运行时，它不会做任何它应该做的事情，而且它应该工作10-20秒，我在调试代码中看到，它会立即执行 我正在用以下代码启动我的控制台应用程序：C# 如何从Windows服务运行控制台应用程序？,c#,windows-services,console-application,C#,Windows Services,Console Application,我有一个用c#编写的windows服务，我需要从中运行控制台应用程序。 控制台应用程序也是用c#编写的 控制台应用程序在非从windows服务运行时运行正常。当它从ws运行时，它不会做任何它应该做的事情，而且它应该工作10-20秒，我在调试代码中看到，它会立即执行 我正在用以下代码启动我的控制台应用程序： proc.Start(fullPathToConsole, args); proc.WaitForExit(); 控制台的路径是正确的，当我试图从cmd或只是在资源管理器（不带args）中运

proc.WaitForExit();
如果您有任何意见，我们将非常高兴 从Windows Vista开始，服务无法与桌面交互。您将无法看到从服务启动的任何窗口或控制台窗口。看这个 在其他操作系统上，在服务选项中有一个名为“允许服务与桌面交互”的选项。从技术上讲，您应该为将来编程，并且应该遵循Vista指南，即使您不在Vista上使用它 如果您仍然希望运行一个从不与桌面交互的应用程序，请尝试将该进程指定为不使用shell
ProcessStartInfo info = new ProcessStartInfo(@"c:\myprogram.exe");
info.UseShellExecute = false;
info.RedirectStandardError = true;
info.RedirectStandardInput = true;
info.RedirectStandardOutput = true;
info.CreateNoWindow = true;
info.ErrorDialog = false;
info.WindowStyle = ProcessWindowStyle.Hidden;
Process process = Process.Start(info);
其次，您将所有控制台交互重定向到内部流（请参阅
process.StandardInputprocess.StandardOutput如果需要某种类型的用户交互，则需要创建客户端应用程序，并通过rpc、套接字或命名管道与服务和/或子应用程序通信。需要服务连接到服务控制管理器，并在启动时提供反馈（即告诉SCM“我还活着！”）。这就是为什么C#应用程序有不同的服务项目模板。您有两种选择：
- 在srvany.exe上包装您的exe，如KB所述
- 让您的C#应用程序检测何时作为服务启动（例如命令行参数），并将控制切换到继承并正确实现服务的类
using (System.Diagnostics.Process process = new System.Diagnostics.Process())
{
process.StartInfo = new System.Diagnostics.ProcessStartInfo(@"c:\windows\system32\cmd.exe");
process.StartInfo.CreateNoWindow = true;
process.StartInfo.ErrorDialog = false;
process.StartInfo.RedirectStandardError = true;
process.StartInfo.RedirectStandardInput = true;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.UseShellExecute = false;
process.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
process.Start();
//// do some other things while you wait...
System.Threading.Thread.Sleep(10000); // simulate doing other things...
process.StandardInput.WriteLine("exit"); // tell console to exit
if (!process.HasExited)
{
process.WaitForExit(120000); // give 2 minutes for process to finish
if (!process.HasExited)
{
process.Kill(); // took too long, kill it off
}
}
}
我有一个Windows服务，我在服务的构造函数中添加了以下行：
using System.Diagnostics;
try {
Process p = Process.Start(@"C:\Windows\system32\calc.exe");
} catch {
Debugger.Break();
}
但正如其他人所说，与桌面的交互受到微软的反对，并且在Vista中基本上被禁用。因此，即使你能让它在XP中工作，我也不知道你能在Vista中工作。在Windows服务中运行任何应用程序，例如“.exe”这样做很奇怪，因为算法没有那么有效。我使用这个类：
