You can use Registry and RegistryKey classes:

using (var registryKey = Registry.LocalMachine.OpenSubKey("Software\\Microsoft\\Windows NT\\CurrentVersion\\Image File Execution Options\\csgo.exe\\PerfOptions"))
{
    if (registryKey != null)
    {
        var cpuPriorityClass = registryKey.GetValue("CpuPriorityClass"); // read value

        // or

        registryKey.SetValue("CpuPriorityClass", 3, RegistryValueKind.DWord); // set value
    }
}
