C#检验IIS版本、SQL Server版本、SilverLight版本

之前做一个小项目，使用C#检验这些软件的版本，到处找了一些代码，也能作用，记录一下，以防以后用到。

一、检验IIS版本

public static bool checkIIS(string destVersion)

{

            try

            {

                RegistryKey rk = Registry.LocalMachine;

                RegistryKey ver = rk.OpenSubKey(@"SOFTWARE\Microsoft\InetStp");

                int majorVersion = Convert.ToInt32(ver.GetValue("majorversion"));

                int minorVersion = Convert.ToInt32(ver.GetValue("minorversion"));

                Version versionStr = new Version(majorVersion + "." + minorVersion);

                if (versionStr >= new Version(destVersion))

                    return true;

                return false;

            }

            catch

            {

                return false;

            }

}

二、检验SQL Server版本

public static bool checkSQLServer(string destVersion)

        {

            RegistryKey localKey;

            if (Environment.Is64BitOperatingSystem)

                localKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64);

            else

                localKey = RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry32);

            RegistryKey sub = localKey.OpenSubKey(@"SOFTWARE\Microsoft\Microsoft SQL Server");

            object keyInst = null;

            if (sub != null)

                keyInst = sub.GetValue("InstalledInstances");

            if (keyInst != null)

            {

                try

                {

                    Version SQLVer = null;

                    foreach (string str in (string[])keyInst)

                    {

                        RegistryKey subSQL = localKey.OpenSubKey(@"SOFTWARE\Microsoft\Microsoft SQL Server\Instance Names\SQL");

                        object keySQL = subSQL.GetValue(str);

                        RegistryKey subVer = localKey.OpenSubKey(@"SOFTWARE\Microsoft\Microsoft SQL Server\" + (string)keySQL + @"\Setup");

                        object keyVer = subVer.GetValue("Version");

                        //get version numer

                        SQLVer = new Version((string)keyVer);

                    }

                    //SQL Version should >= 12.1.4100.1

                    Version tagVer = new Version(destVersion);

                    if (SQLVer >= tagVer)

                    {

                        return true;

                    }

                    else

                    {

                        return false;

                    }

                }

                catch

                {

                    return false;

                }

            }

            else

                return false;

        }

三、检验SilverLight版本

public static bool checkSilverLight(string destVersion)

        {

            try

            {

                Version version;

                RegistryKey rk = Registry.LocalMachine;

                RegistryKey ver = rk.OpenSubKey(@"SOFTWARE\Microsoft\Silverlight");

                if (ver == null)

                    ver = rk.OpenSubKey(@"SOFTWARE\Wow6432Node\Microsoft\Silverlight");

                version = new Version(ver.GetValue("Version").ToString());

                //version >= 5.1

                if (version >= new Version(destVersion))

                    return true;

                return false;

            }

            catch

            {

                return false;

            }

        }
