Question

我正在开发一个使用MSMQ进行进程间通信的应用程序，我需要安装项目才能安装该服务（如果尚未安装）。我已经查看了有关将其作为先决条件的信息，但到目前为止，我一直未能成功找到这个。有什么想法吗？

Answer 1

我自己发现了答案...... Windows组件安装程序并没有因为在任何给定时间无法安装多个MSI而瘫痪，因此我可以使用自定义安装程序操作来执行命令行用于安装MSMQ的脚本。

这是我的安装程序类（您的选项可能会有所不同）：

public partial class MSMQInstaller : Installer
{
    public MSMQInstaller()
    {
        InitializeComponent();
    }

    [DllImport("kernel32")]
    static extern IntPtr LoadLibrary(string lpFileName);

    [DllImport("kernel32.dll", SetLastError = true)]
    static extern bool FreeLibrary(IntPtr hModule);

    public override void Install(IDictionary stateSaver)
    {
        base.Install(stateSaver);

        bool loaded;

        try
        {
            IntPtr handle = LoadLibrary("Mqrt.dll");

            if (handle == IntPtr.Zero || handle.ToInt32() == 0)
            {
                loaded = false;
            }
            else
            {
                loaded = true;

                FreeLibrary(handle);
            }
        }
        catch
        {
            loaded = false;
        }

        if (!loaded)
        {
            if (Environment.OSVersion.Version.Major < 6) // Windows XP or earlier
            {
                string fileName = System.IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.System), "MSMQAnswer.ans");

                using (System.IO.StreamWriter writer = new System.IO.StreamWriter(fileName))
                {
                    writer.WriteLine("[Version]");
                    writer.WriteLine("Signature = \"$Windows NT$\"");
                    writer.WriteLine();
                    writer.WriteLine("[Global]");
                    writer.WriteLine("FreshMode = Custom");
                    writer.WriteLine("MaintenanceMode = RemoveAll");
                    writer.WriteLine("UpgradeMode = UpgradeOnly");
                    writer.WriteLine();
                    writer.WriteLine("[Components]");
                    writer.WriteLine("msmq_Core = ON");
                    writer.WriteLine("msmq_LocalStorage = ON");
                }

                using (System.Diagnostics.Process p = new System.Diagnostics.Process())
                {
                    System.Diagnostics.ProcessStartInfo start = new System.Diagnostics.ProcessStartInfo("sysocmgr.exe", "/i:sysoc.inf /u:\"" + fileName + "\"");

                    p.StartInfo = start;

                    p.Start();
                    p.WaitForExit();
                }
            }
            else // Vista or later
            {
                using (System.Diagnostics.Process p = new System.Diagnostics.Process())
                {
                    System.Diagnostics.ProcessStartInfo start = new System.Diagnostics.ProcessStartInfo("ocsetup.exe", "MSMQ-Container;MSMQ-Server /passive");

                    p.StartInfo = start;

                    p.Start();
                    p.WaitForExit();
                }
            }
        }
    }
}

pkgmgr命令怎么样？

pkgmgr / iu：MSMQ-Container; MSMQ-Server
