在注册表中创建密钥

Question

I am developing a WPF application. I want to create a key in the registry in the below path with key, value ( myapp.exe , 2710 ).

HKEY_LOCAL_MACHINE\\SOFTWARE\\Microsoft\\Internet Explorer\\MAIN\\FeatureControl\\FEATURE_BROWSER_EMULATION.

Can any one suggest how to do this from the installer class, OnBeforeInstall method.

Answer 1

you can use below code for create a key and put value.

 private string _subKey = "SOFTWARE\\Microsoft\\Internet Explorer\\MAIN\\FeatureControl\\FEATURE_BROWSER_EMULATION";
    private string SubKey
    {
        get { return _subKey; }
        set { _subKey = value; }
    }

    private RegistryKey _baseRegistryKey = Registry.LocalMachine;

    private RegistryKey BaseRegistryKey
    {
        get { return _baseRegistryKey; }
        set { _baseRegistryKey = value; }
    }

   private bool WriteDbToRegistry(string keyName, object value)
    {
        try
        {
            var rk = BaseRegistryKey;
            var sk1 = rk.CreateSubKey(SubKey);
            if(sk1 != null) sk1.SetValue(keyName.ToUpper(), value);
            return true;
        }
        catch(Exception e)
        {
            MessageBox.Show("Please run your App as Administrator.", "Administrator");
            return false;
        }
    }

 bool results = WriteDbToRegistry("myapp.exe", "2710");

hope this may be helpful.

Install the Microsoft.Win32.Registry NuGet package, and usse it like this:

    var keyName = @"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\MAIN\FeatureControl\FEATURE_BROWSER_EMULATION";
    Registry.SetValue(keyName , "myapp.exe", 2710, RegistryValueKind.DWord);

Setting the value adds it if it's missing.

You can find more information in the documentation .
