如何启动一个进程以从 Windows 服务运行 bat 文件

Question

尝试从 Windows 服务运行 bat 文件。 代码如下：

try
            {
                SecureString securePwd = new SecureString();
                foreach (char c in pwd)
                {
                    securePwd.AppendChar(c);
                }
                Process process = new Process();
                process.StartInfo.UseShellExecute = false;
                process.StartInfo.FileName = @"CMD.exe";  //The file in that DIR.
                process.StartInfo.WorkingDirectory = @"C:\";
                process.StartInfo.Arguments = @"/C " + filePath;
                process.StartInfo.Verb = "runas";
                process.StartInfo.UserName = user;
                process.StartInfo.Password = securePwd;
                process.Start();
            }
            catch (Exception ex)
            {
                EventLog myEventLog = new EventLog { Source = "MoC LaneUpdate" };
                myEventLog.WriteEntry(ex.ToString(), EventLogEntryType.Error);
            }

我已经验证了相同的代码在非服务中运行时是否有效。我也没有收到错误消息，但是 .bat 文件没有运行，至少在我当前的用户会话中没有出现。我的文件是否在后台会话中运行？如何在 startinfo 中指定的用户中运行批处理文件？

Answer 1

对于运行 Windows 服务的桌面应用程序，服务需要创建用户进程。

服务是在session 0中创建的，在哪里不允许图形界面它们不显示，正在必须在用户登录的部分创建一个进程（0除外）。

为此需要使用windows api的资源。

以下 vb.net 中的示例。

ps：对不起我的英语。

 Try

        Dim UserTokenHandle As IntPtr = IntPtr.Zero
        Dim ProcInfo As New WindowsApi.PROCESS_INFORMATION
        Dim StartInfo As New WindowsApi.STARTUPINFOW

        'obtain an access token(handle) for the session that the user logged in is using.
        WindowsApi.WTSQueryUserToken(WindowsApi.WTSGetActiveConsoleSessionId, UserTokenHandle)

        'widows specification for the process that will be created
        StartInfo.cb = CUInt(Runtime.InteropServices.Marshal.SizeOf(StartInfo))

        'create a new process to run on the user session represented by UserTokenHandle that was obtained in WTSQueryUserToken
        WindowsApi.CreateProcessAsUser(UserTokenHandle,"C:\FILE_TO_RUN.EXE", IntPtr.Zero, IntPtr.Zero, IntPtr.Zero, False, 0, IntPtr.Zero, Nothing, StartInfo, ProcInfo)

        'checks whether the UserTokenHandle is nonzero
        If Not UserTokenHandle = IntPtr.Zero Then
            WindowsApi.CloseHandle(UserTokenHandle)
        End If

    Catch ex As Exception
       throw
    End Try
