C# 将现有服务设置为"；自动（延迟启动）“；

我正在尝试在C#中将已安装的windows服务设置为自动延迟启动。如何将windows服务设置为

Automatic (Delayed Start) 

在ServiceStartMode枚举中找不到该值

编辑：1

public class ServiceAutoStartInfo
{
    [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Auto)]
    private struct SERVICE_DELAYED_AUTO_START_INFO
    {

        public bool fDelayedAutostart;
    }

    [DllImport("advapi32.dll", SetLastError = true, CharSet = CharSet.Auto)]
    [return: MarshalAs(UnmanagedType.Bool)]
    private static extern bool ChangeServiceConfig2(IntPtr hService, int dwInfoLevel, IntPtr lpInfo);

    // Service configuration parameter 
    const int SERVICE_CONFIG_DELAYED_AUTO_START_INFO = 3;

    public bool ChangeDelayedAutoStart(IntPtr hService, bool delayed)
    {


        // Validate service handle
        if (hService != IntPtr.Zero)
        {


            // Create 
            SERVICE_DELAYED_AUTO_START_INFO info = new SERVICE_DELAYED_AUTO_START_INFO();

            // Set the DelayedAutostart property
            info.fDelayedAutostart = delayed;

            // Allocate necessary memory
            IntPtr hInfo = Marshal.AllocHGlobal(Marshal.SizeOf(

            typeof(SERVICE_DELAYED_AUTO_START_INFO)));

            // Convert structure to pointer
            Marshal.StructureToPtr(info, hInfo, true);

            // Change the configuration
            bool result = ChangeServiceConfig2(hService, SERVICE_CONFIG_DELAYED_AUTO_START_INFO, hInfo);

            // Release memory
            Marshal.FreeHGlobal(hInfo);

            return result;
        }

        return false;
    }
}

我这样称呼它：

var controller = new ServiceController(s.ServiceName);
var autoDelay = new ServiceAutoStartInfo();
autoDelay.ChangeDelayedAutoStart(controller.ServiceHandle.DangerousGetHandle(), true);

---

但是没有结果。

更新：这只适用于设置新服务，而不是OP要求的：

您可以使用

ServiceInstaller

的属性

installer.DelayedAutoStart = true;

---

研究调用Windows函数，将

SERVICE\u CONFIG\u DELAYED\u AUTO\u START\u INFO

的

dwInfoLevel

和

SERVICE\u DELAYED\u AUTO\u START\u INFO

结构设置为

TRUE

或者，可以使用命令行执行此操作：

sc.exe config <servicename> start= delayed-auto

sc.exe配置启动=延迟自动

我认为您需要将ChangeServiceConfig和ChangeServiceConfig2这两种方法结合起来

伪代码如下：

public static void ChangeServiceStartupType(ServiceStartupType type, ...)
{
    if (type == AutomaticDelayed)
    {
        if (ChangeServiceConfig2(.., DelayedAutoStart, ..))
        {
            ChangeServiceConfig(.., Automatic, ..);
        }
    }
    else
    {
        ChangeServiceConfig2(.., !DelayedAutoStart, ..)
        ChangeServiceConfig(.., type, ..)
    }
}

---

编辑：在请求非延迟启动类型时，还需要删除“延迟自动”。否则将无法设置“自动”类型。（“自动延迟”覆盖“自动”）

我正在使用以下功能，这在Windows 7上适用（以管理员身份运行时）：

---

服务\u延迟\u自动\u启动\u信息结构文档状态：

fDelayedAutostart

如果此成员为TRUE，则在其他自动启动后启动服务 服务启动加上短暂的延迟。否则，服务将被取消 在系统引导期间启动

除非服务是自动启动服务，否则将忽略此设置

---

因此我认为如果服务不是自动启动，它不会将其更改为自动延迟，你必须使用sc.exe

为什么不在MMC服务中更改它的启动？@OverKiller我正在为我的项目构建一个自动部署管理器，所以我试图在代码中更改它。@oleksii我不相信这是一个重复，因为这个问题是针对一个已经安装的服务，而你链接到的那个是在安装过程中谈论的process@lc收回我的voteI没有服务安装程序，因为服务已经安装。操作，抱歉…-让我检查另一个解决方案。我尝试了ChangeServiceConfig2方法，但没有结果，我可以用代码编辑我的帖子。@Tan它是否返回非零值（表示成功），或者如果不是，错误代码是什么？您的进程是否已提升，或者您是否有权修改服务的配置？我有权使用管理员帐户进行即时通讯。它不会返回任何错误。但是启动类型jsut不会从手动更新为自动延迟。@Tan我不确定这是否仍然相关，但建议您可能需要在它出现更新之前重新启动。我是否读取了文档错误，或者不是映射到

uint

的DWORD？因为在这种情况下，他应该通过

3
