.net - 如何在运行时检测XNA版本？

Question

我有一个为.NET 2.0编写的启动程序/更新程序应用程序，需要检查用户是否已安装XNA 4.0。

如果不是，则要求用户安装它。

怎么做？

这是我为此编写的函数:

    public string CheckXNAFramework(out bool ok)
    {
        string output = "";

        string baseKeyName = @"SOFTWARE\Microsoft\XNA\Game Studio";
        Microsoft.Win32.RegistryKey installedFrameworkVersions = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(baseKeyName);

        string[] versionNames = installedFrameworkVersions.GetSubKeyNames();

        bool found = false;
        foreach (string s in versionNames)
        {
            if (s == "v4.0")
            {
                found = true;
                break;
            }
        }
        if (found)
        {
            output += "Microsoft XNA Framework found successfully.\n";
            ok = true;
        }
        else
        {
            output += "Correct version of the Microsoft XNA Framework not found. Please install version 4.0 or higher.\n";
            ok = false;
        }

        return output;
    }
