下面是一些更好的代码，我想。我能想出的最好的是基于Windows版本在DX10或DX11的情况进行检查。这是不是100％准确（因为Vista的可升级到DX11，但我不检查这个），但有总比没有好。

Below is some better code I think. The best I can come up with is a check based on Windows version in the case of DX10 or DX11. This is not 100% accurate (because Vista can be upgraded to DX11 but I do not check for this), but better than nothing.

    private int GetDirectxMajorVersion()
    {
        int directxMajorVersion = 0;

        var OSVersion = Environment.OSVersion;

        // if Windows Vista or later
        if (OSVersion.Version.Major >= 6)
        {
            // if Windows 7 or later
            if (OSVersion.Version.Major > 6 || OSVersion.Version.Minor >= 1)
            {
                directxMajorVersion = 11;
            }
            // if Windows Vista
            else
            {
                directxMajorVersion = 10;
            }
        }
        // if Windows XP or earlier.
        else
        {
            using (RegistryKey key = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\DirectX"))
            {
                string versionStr = key.GetValue("Version") as string;
                if (!string.IsNullOrEmpty(versionStr))
                {
                    var versionComponents = versionStr.Split('.');
                    if (versionComponents.Length > 1)
                    {
                        int directXLevel;
                        if (int.TryParse(versionComponents[1], out directXLevel))
                        {
                            directxMajorVersion = directXLevel;
                        }
                    }
                }
            }
        }

        return directxMajorVersion;
    }
