我正在尝试将已安装的 Windows服务设置为C＃中的自动延迟启动。如何将Windows服务设置为
Automatic (Delayed Start)
无法在ServiceStartMode枚举中找到该值。
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;
}
}
这就是我所说的：
var controller = new ServiceController(s.ServiceName);
var autoDelay = new ServiceAutoStartInfo();
autoDelay.ChangeDelayedAutoStart(controller.ServiceHandle.DangerousGetHandle(), true);
但没有结果。

调用Windows ChangeServiceConfig2函数，dwInfoLevel SERVICE_CONFIG_DELAYED_AUTO_START_INFO和SERVICE_DELAYED_AUTO_START_INFO结构fDelayedAutostart设置为TRUE。< / p>
或者，您可以使用命令行执行此操作：
sc.exe config <servicename> start= delayed-auto

你这样称呼它：
var serviceController = new ServiceController("Windows Update");
try
{
serviceController.SetStartMode(ServiceStartModeEx.DelayedAutomatic);
}
finally
{
serviceController.Close();
}

更新：这仅适用于设置新服务，而不是OP要求的内容：
<击>
您可以使用ServiceInstaller。{/ strike>
DelayedAutoStart属性
installer.DelayedAutoStart = true;

我认为你需要结合使用ChangeServiceConfig和ChangeServiceConfig2两种方法。
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：您还需要在请求非延迟启动类型时删除“延迟自动”。否则将无法设置“自动”类型。 （“自动延迟”覆盖“自动”）
答案 4 :(得分：0)
SERVICE_DELAYED_AUTO_START_INFO 结构文档说明：
<块引用>fDelayedAutostart
如果该成员为TRUE，则服务在其他自动启动后启动 服务启动加上短暂的延迟。否则，服务是 在系统启动期间启动。
除非服务是自动启动服务，否则将忽略此设置。
所以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，您将不得不使用 sc.exe
