如何以编程方式启用net.tcp端口共享服务?

有多种方法可以做到这一点,这取决于您想要的解决方案的“纯”程度。这里有一些选择。 请注意,所有这些解决方案都需要管理权限,并且必须在提升的过程中运行。

通过C使用命令提示#

这将涉及炮击 sc.exe 以及通过命令行参数更改服务的启动类型。这与您上面提到的解决方案类似,只是不需要进行注册表黑客攻击。

namespace Sample
{
    using System;
    using System.Diagnostics;
    using System.Globalization;

    internal class ServiceSample
    {
        private static bool ChangeStartupType(string serviceName, string startupType)
        {
            string arguments = string.Format(
                CultureInfo.InvariantCulture,
                "config {0} start= {1}",
                serviceName,
                startupType);
            using (Process sc = Process.Start("sc.exe", arguments))
            {
                sc.WaitForExit();
                return sc.ExitCode == 0;
            }
        }

        private static void Main()
        {
            ServiceSample.ChangeStartupType("NetTcpPortSharing", "auto");
        }
    }
}

使用WMI

这需要程序集引用 System.Management.dll . 这里我们将使用WMI功能 ChangeStartMode 为了服务。

namespace Sample
{
    using System;
    using System.Globalization;
    using System.Management;

    internal class ServiceSample
    {
        private static bool ChangeStartupType(string serviceName, string startupType)
        {
            const string MethodName = "ChangeStartMode";
            ManagementPath path = new ManagementPath();
            path.Server = ".";
            path.NamespacePath = @"root\CIMV2";
            path.RelativePath = string.Format(
                CultureInfo.InvariantCulture,
                "Win32_Service.Name='{0}'",
                serviceName);
            using (ManagementObject serviceObject = new ManagementObject(path))
            {
                ManagementBaseObject inputParameters = serviceObject.GetMethodParameters(MethodName);
                inputParameters["startmode"] = startupType;
                ManagementBaseObject outputParameters = serviceObject.InvokeMethod(MethodName, inputParameters, null);
                return (uint)outputParameters.Properties["ReturnValue"].Value == 0;
            }
        }

        private static void Main()
        {
            ServiceSample.ChangeStartupType("NetTcpPortSharing", "Automatic");
        }
    }
}

对Win32 API使用P/Invoke

对某些人来说,这是最“纯粹”的方法,尽管要想正确处理问题更难。基本上你要打电话 ChangeServiceConfig 来自.NET。但是,这要求您首先打电话 OpenService 对于指定的服务和 那个 需要呼叫 OpenSCManager 事先(别忘了 CloseServiceHandle 等你做完了!).

注意:此代码仅用于演示目的。它不包含任何错误处理,可能会泄漏资源。应使用适当的实现 SafeHandle 类型以确保正确清理,并应添加适当的错误检查。

namespace Sample
{
    using System;
    using System.ComponentModel;
    using System.Runtime.InteropServices;

    internal class ServiceSample
    {
        private const uint SC_MANAGER_CONNECT = 0x1;
        private const uint SERVICE_CHANGE_CONFIG = 0x2;
        private const uint STANDARD_RIGHTS_WRITE = 0x20000;

        private const uint SERVICE_NO_CHANGE = 0xFFFFFFFF;

        private const uint SERVICE_AUTO_START = 0x2;
        private const uint SERVICE_DEMAND_START = 0x3;
        private const uint SERVICE_DISABLED = 0x4;

        [DllImport("advapi32.dll", SetLastError = true)]
        private static extern IntPtr OpenSCManager(string lpMachineName, string lpDatabaseName, uint dwDesiredAccess);

        [DllImport("advapi32.dll", SetLastError = true)]
        private static extern IntPtr OpenService(IntPtr hSCManager, string lpServiceName, uint dwDesiredAccess);

        [DllImport("advapi32.dll", SetLastError = true)]
        private static extern bool ChangeServiceConfig(IntPtr hService, uint dwServiceType, uint dwStartType, uint dwErrorControl, string lpBinaryPathName, string lpLoadOrderGroup, IntPtr lpdwTagId, string lpDependencies, string lpServiceStartName, string lpPassword, string lpDisplayName);

        [DllImport("advapi32.dll", SetLastError = true)]
        private static extern bool CloseServiceHandle(IntPtr hSCObject);

        private static bool ChangeStartupType(string serviceName, uint startType)
        {
            IntPtr scManager = ServiceSample.OpenSCManager(null, null, ServiceSample.SC_MANAGER_CONNECT);
            IntPtr service = ServiceSample.OpenService(scManager, serviceName, ServiceSample.SERVICE_CHANGE_CONFIG | ServiceSample.STANDARD_RIGHTS_WRITE);
            bool succeeded = ServiceSample.ChangeServiceConfig(service, ServiceSample.SERVICE_NO_CHANGE, startType, ServiceSample.SERVICE_NO_CHANGE, null, null, IntPtr.Zero, null, null, null, null);
            ServiceSample.CloseServiceHandle(service);
            ServiceSample.CloseServiceHandle(scManager);

            return succeeded;
        }

        private static void Main()
        {
            ServiceSample.ChangeStartupType("NetTcpPortSharing", ServiceSample.SERVICE_AUTO_START);
        }
    }
}

使用ServiceController有一个简单的答案

System.ServiceProcess.ServiceController netTcpPortSharingService = new System.ServiceProcess.ServiceController("NetTcpPortSharing");

if (netTcpPortSharingService != null)
            {
                if(netTcpPortSharingService.Status!=ServiceControllerStatus.Running && netTcpPortSharingService.Status!=ServiceControllerStatus.StartPending)
                {
                    netTcpPortSharingService.Start();
                }
            }
