如何从c#读取注册表数据

using Microsoft.Win32;

class Program
{
    static void Main()
    {
        // 打开注册表的指定键
        using (RegistryKey key = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Windows\CurrentVersion"))
        {
            if (key != null)
            {
                // 读取键的值
                object value = key.GetValue("ProgramFilesDir");
                if (value != null)
                {
                    // 将结果转换为字符串并打印
                    Console.WriteLine("Program Files directory: " + value.ToString());
                }
                else
                {
                    Console.WriteLine("Value not found.");
                }
            }
            else
            {
                Console.WriteLine("Key not found.");
            }
        }
    }
}
