迭代注册表项

正如这里建议的那样,我需要遍历条目

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\

找出我的应用程序的安装路径.如何迭代,以便我可以找到给定DisplayName的 InstallLocation值.如何在C#中高效地完成它.

以下是实现目标的代码:

class Program
{
    static void Main(string[] args)
    {
        RegistryKey key = Registry.LocalMachine.OpenSubKey("Software\\Microsoft\\Windows\\CurrentVersion\\Uninstall");
        foreach (var v in key.GetSubKeyNames())
        {
            Console.WriteLine(v);

            RegistryKey productKey = key.OpenSubKey(v);
            if (productKey != null)
            {
                foreach (var value in productKey.GetValueNames())
                {
                    Console.WriteLine("\tValue:" + value);

                    // Check for the publisher to ensure it's our product
                    string keyValue = Convert.ToString(productKey.GetValue("Publisher"));
                    if (!keyValue.Equals("MyPublisherCompanyName", StringComparison.OrdinalIgnoreCase))
                        continue;

                    string productName = Convert.ToString(productKey.GetValue("DisplayName"));
                    if (!productName.Equals("MyProductName", StringComparison.OrdinalIgnoreCase))
                        return;

                    string uninstallPath = Convert.ToString(productKey.GetValue("InstallSource"));

                    // Do something with this valuable information
                }
            }
        }

        Console.ReadLine();
    }
}
