获取已安装的Msi的产品代码

如何解决获取已安装的Msi的产品代码

| 我有一个C＃程序，必须在其中获取已安装的msi的产品代码。我只有msi名称作为输入。可以通过编程方式完成吗？     

解决方法

        有最快，最简单的方法-将WMI与条件查询字符串一起使用。

    public string GetProductCode(string productName)
    {
        string query = string.Format(\"select * from Win32_Product where Name=\'{0}\'\",productName);
        using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(query))
        {
            foreach (ManagementObject product in searcher.Get())
                return product[\"IdentifyingNumber\"].ToString();
        }
        return null;
    }

    ,        这个问题的答案有帮助吗？他们想获得产品名称，但是也许也适用于产品代码？ 编辑 如果您没有MSI文件本身来访问数据库（如上述其他问题的链接所示），则可以尝试在以下注册表路径中搜索MSI文件的名称：

HKEY_CLASSES_ROOT\\Installer\\Products\\*\\SourceList 

Products

分支下有很多条目。它们每个都是产品密钥。每个分支都应包含“ 3”节点，而该节点又应包含值“ 4”。该值保存MSI文件的名称。 所以我要做的是：

for each key in Products
{
    open SourceList subkey
    read PackageName value
    if name equals my msi file name
    {
        return key-name formatted as GUID
    }
}

    ,        这是我用来获取任何MSI的

UninstallString

的代码。

private string GetUninstallString(string msiName)
{
    Utility.WriteLog(\"Entered GetUninstallString(msiName) - Parameters: msiName = \" + msiName);
    string uninstallString = string.Empty;
    try
    {
        string path = \"SOFTWARE\\\\Microsoft\\\\Windows\\\\CurrentVersion\\\\Installer\\\\UserData\\\\S-1-5-18\\\\Products\";

        RegistryKey key = Registry.LocalMachine.OpenSubKey(path);

        foreach (string tempKeyName in key.GetSubKeyNames())
        {
            RegistryKey tempKey = key.OpenSubKey(tempKeyName + \"\\\\InstallProperties\");
            if (tempKey != null)
            {
                if (string.Equals(Convert.ToString(tempKey.GetValue(\"DisplayName\")),msiName,StringComparison.CurrentCultureIgnoreCase))
                {
                    uninstallString = Convert.ToString(tempKey.GetValue(\"UninstallString\"));
                    uninstallString = uninstallString.Replace(\"/I\",\"/X\");
                    uninstallString = uninstallString.Replace(\"MsiExec.exe\",\"\").Trim();
                    uninstallString += \" /quiet /qn\";
                    break;
                }
            }
        }

        return uninstallString;
    }
    catch (Exception ex)
    {
        throw new ApplicationException(ex.Message);
    }
}

这样会得到如下结果：

MsiExec.exe /I{6BB09011-69E1-472F-ACAD-FA0E7DA3E2CE}

从该字符串中，您可以将大括号{}中的子字符串作为

6BB09011-69E1-472F-ACAD-FA0E7DA3E2CE

。我希望这可能是产品代码。     ,        此代码直接从MSI文件获取产品代码。因此，这允许在不安装文件的情况下读取代码。

class MsiHandle : SafeHandleMinusOneIsInvalid
{
    public MsiHandle()
        : base(true)
    { }

    protected override bool ReleaseHandle()
    {
        return NativeMethods.MsiCloseHandle(handle) == 0;
    }
}

class NativeMethods
{
    const string MsiDll = \"Msi.dll\";

    [DllImport(MsiDll,CharSet = CharSet.Unicode,ExactSpelling = true)]
    public extern static uint MsiOpenPackageW(string szPackagePath,out MsiHandle product);

    [DllImport(MsiDll,ExactSpelling=true)]
    public extern static uint MsiCloseHandle(IntPtr hAny);

    [DllImport(MsiDll,ExactSpelling = true)]
    static extern uint MsiGetProductPropertyW(MsiHandle hProduct,string szProperty,StringBuilder value,ref int length);


    [DllImport(MsiDll,ExactSpelling = true)]
    public static extern int MsiSetInternalUI(int value,IntPtr hwnd);

    public static uint MsiGetProductProperty(MsiHandle hProduct,out string value)
    {
        StringBuilder sb = new StringBuilder(1024);
        int length = sb.Capacity;
        uint err;
        value = null;
        if(0 == (err = MsiGetProductPropertyW(hProduct,szProperty,sb,ref length)))
        {
            sb.Length = length;
            value = sb.ToString();
            return 0;
        }

        return err;
    }
}

static class Program
{
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static int Main(string[] args)
    {
        string msiFile = args[0];

        NativeMethods.MsiSetInternalUI(2,IntPtr.Zero); // Hide all UI. Without this you get a MSI dialog

        MsiHandle msi;
        uint err;
        if (0 != (err = NativeMethods.MsiOpenPackageW(args[0],out msi)))
        {
            Console.Error.WriteLine(\"Can\'t open MSI,error {0}\",err);
            return 1;
        }

        // Strings available in all MSIs
        string productCode;
        using (msi)
        {
           if (0 != NativeMethods.MsiGetProductProperty(msi,\"ProductCode\",out productCode))
                throw new InvalidOperationException(\"Can\'t obtain product code\");

           Console.WriteLine(productCode);
           return 0;
        }
    }
}

private static bool GetUninstallString(string ProductName)
{
    try
    {
        RegistryKey localKey = RegistryKey.OpenBaseKey(Microsoft.Win32.RegistryHive.LocalMachine,RegistryView.Registry64);
        var key = localKey.OpenSubKey(@\"SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall\") ??
            localKey.OpenSubKey(
                @\"SOFTWARE\\Wow6432Node\\Microsoft\\Windows\\CurrentVersion\\Uninstall\");

        if (key == null)
                return false;

        return key.GetSubKeyNames()
                .Select(keyName => key.OpenSubKey(keyName))
                .Select(subkey => subkey.GetValue(\"DisplayName\") as string)
                .Any(displayName => displayName != null && displayName.Contains(ProductName));
     }
     catch
     {
         // Log message                  
         return false;
     }
 }

这对于按产品名称搜索字符串非常有用
