.net中如何启动windows服务?

Question

一个winform程序，有个窗体需要系统启动Print Spooler 服务(RPC),由于有些用户的这个服务没有自动启动，所以在窗体加载的时候先判断是否启动，如果没有，则先启动，代码如下:
//  Print Spooler
                ServiceController controller = new ServiceController("Spooler");
                if (controller.Status == ServiceControllerStatus.Stopped)
                {
                    controller.Start();
                    controller.Refresh();
                }
可现在如果此服务的启动类型是手动或者自动的话，可以正常启动，如果这个服务的启动类型是禁用的话，上面的代码就会出错，我尝试过修改启动类型，可总是不成功，请教.....

Answer 1

通过Process 调用 sc 修改服务启动类型
命令格式如下sc config 服务名称 start= demand

Answer 2

看来CSDN重新开盘人不多呀，继续等待...

Answer 3

You might use WMI to change the service's starting mode:    enum StartServiceResult
    {
        Success = 0,
        AccessDenied = 2,
        ServiceAlreadyRunning = 10,
        ServiceDisabled = 14
    }    /// <returns>error message, if any</returns>
    static string StartService(string serviceName)
    {
        string errMsg = string.Format("Unable to open '{0}' service", serviceName);
        string query = string.Format("select * from Win32_Service where Name='{0}'", serviceName);
        ManagementObjectSearcher searcher = new ManagementObjectSearcher(query);        foreach(ManagementObject obj in searcher.Get())
        {
            uint result = (uint)obj.InvokeMethod("StartService", null);
            switch ((StartServiceResult)result)
            {
                case StartServiceResult.Success:
                case StartServiceResult.ServiceAlreadyRunning:
                    errMsg = null;
                    break;
                case StartServiceResult.ServiceDisabled:
                    result = (uint)obj.InvokeMethod("ChangeStartMode", new string[] { "Automatic" });
                    if ((StartServiceResult)result == StartServiceResult.Success)
                    {
                        errMsg = StartService( serviceName );
                    }
                    else
                    {
                        errMsg = string.Format("Error Changing Service Start Mode: ({0})", result);
                    }
                    break;
                default:
                    errMsg = string.Format("Error Starting Service: ({0})", result);
                    break;
            }
            break;
        }        if( errMsg != null )
        {
           // wait until service's status is Running or time-out
        }        return errMsg;
    }

Answer 4

我找了段代码，还是不行
//设置服务的启动类型//sServiceName服务名称//iStartType要设置的启动类型//返回成功状态 true：成功，false：失败 public Boolean SetWindowsServiceStartType(String sServiceName, int iStartType)
        {
            try
            {
                System.Diagnostics.ProcessStartInfo objProcessInf = new System.Diagnostics.ProcessStartInfo();                objProcessInf.FileName = "cmd.exe";                objProcessInf.CreateNoWindow = false;
                objProcessInf.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;                string sStartState = "boot";                switch (iStartType)
                {
                    case 1:
                        {
                            sStartState = "system";
                            break;
                        }
                    case 2:
                        {
                            sStartState = "auto";
                            break;
                        }
                    case 3:
                        {
                            sStartState = "demand";
                            break;
                        }
                    case 4:
                        {
                            sStartState = "disabled";
                            break;
                        }
                    default:
                        {
                            break;
                        }
                }                objProcessInf.Arguments = "/c sc config " + sServiceName + " start= " + sStartState;                System.Diagnostics.Process.Start(objProcessInf);                return true;
            }
            catch
            {
                return false;
            }
        } 先试试楼上的

Answer 5

前一段时间对服务的启动、卸载做过测试，还真没有修改过启动类型
采用gomoku 的方法修改了一下没问题，还是看一下你服务的操作权限吧

Answer 6

从注册表中把要启动的服务修改为自动启动，这是我写的一个小程序，控制台方式，可手动或批处理执行！算是一种变相方式！注册表修改后重启电脑服务自动启动，配置不同参数可以执行注册或卸载服务，这里是用于启动W3SVC相关服务的例子。using System;
using System.Collections.Generic;
using System.Text;
using Microsoft.Win32;
/*

{
    class Program
    {
        static void Main(string[] args)
        {            if (args.Length > 0 && !string.IsNullOrEmpty(args[0]))
            {
                if (args[0].Trim() == "-i" || args[0].Trim() == "/i")
                    RunRegistry(true);
                else if (args[0].Trim() == "-u" || args[0].Trim() == "/u")
                    RunRegistry(false);
                else if (args[0].Trim() == "-?" || args[0].Trim() == "/?")
                {
                    Console.WriteLine("PpmisReg v1.0 用法:\r");
                    Console.WriteLine("Note: RunServices aspnet_state/IISAdmin/W3SVC\n");
                    Console.WriteLine("PpmisReg /i \t执行注册安装\n");
                    Console.WriteLine("PpmisReg /u \t执行注册卸载\n");
                    return;
                }
                else
                    return;

Answer 7

用ServiceController类 http://msdn.microsoft.com/zh-cn/library/system.serviceprocess.servicecontroller_members(en-us,VS.71).aspx

Answer 8

用C# 执行下面的命令
sc config Spooler start= AUTO
net start Spooler

Answer 9

试了一下，gomoku的方法可以解决，至于批处理文件启动服务及改注册表的方法，也试过可以实现，不过感觉是临时解决方法，谢谢大家了!

Answer 12

一下代码供参考 System.ServiceProcess.ServiceController winService = null;
System.TimeSpan timeOut = new TimeSpan(0,1,0);//Set timeout
private void btnReStart_Click(object sender, System.EventArgs e)
{
try
{
InitilizeServiceController();
if (winService.Status == System.ServiceProcess.ServiceControllerStatus.Running)
{
winService.Stop();
winService.WaitForStatus(System.ServiceProcess.ServiceControllerStatus.Stopped,timeOut);//wait service change to stopped status
this.label1.Text = "service status now is :"+winService.Status;
this.label1.Update();
System.Threading.Thread.Sleep(15000);
winService.Start();
winService.WaitForStatus(System.ServiceProcess.ServiceControllerStatus.StartPending,timeOut);//wait service change to start pending status
this.label1.Text = "service status now is :"+winService.Status;
this.label1.Update();
winService.WaitForStatus(System.ServiceProcess.ServiceControllerStatus.Running,timeOut);//wait service change to running status
this.label1.Text = "service status now is :"+winService.Status;
this.label1.Update();
}
else if (winService.Status == System.ServiceProcess.ServiceControllerStatus.Stopped)
{
this.label1.Text = "service status now is :"+winService.Status+",please click start button";
this.label1.Update();
}
else
{
this.label1.Text = "service status now is :"+winService.Status;
this.label1.Update();
} }
catch(Exception ex)
{
this.label1.Text = ex.Message;
this.label1.Update();
}
} /// <summary>
/// Initilize Service Controller
/// </summary>
private void InitilizeServiceController()
{
if (this.txtServiceName.Text.Trim().Length == 0) 
{
throw new Exception("please enter service name");
}
string serviceName = this.txtServiceName.Text;
winService = new System.ServiceProcess.ServiceController(serviceName);//Get service by name
}

Answer 13

调用Kernel32的ChangeServiceConfig，第一个参数正好用 ServiceController.ServiceHandle

Answer 14

常见的有两种方式实现，可以参考我这里的代码和文章，
