Winform读取操作系统提要

Winform读取操作系统摘要
我想读取部分Windows操作系统摘要信息，在网上找的些代码感觉不是很快，但是这个系统信息文件打开却很快，想问下有没有相关代码或类可参考？

------解决思路----------------------
系统版本都在Environment.OSVersion里面
详细的在WMI查询

/// <summary>

        /// 通过WMI查询系统相关类的信息

        /// </summary>

        /// <param name="win32ClassName">组件类名</param>

        /// <param name="propertyNames">要查询的属性列表，为null时将列出所有</param>

        /// <param name="predicate">属性值的筛选条件(空值已排除)</param>

        /// <param name="tips">提示信息</param>

        static void QuerySystemInfoByWmi(string win32ClassName, List<string> propertyNames, Predicate<string> predicate, string tips)

        {

            WriteLine();

            WriteLine("===================={0}====================", win32ClassName);

            if (!string.IsNullOrEmpty(tips)) WriteLine(tips);

            ManagementClass mc = null;

            DateTime start = DateTime.Now;

            try

            {

                mc = new ManagementClass(win32ClassName);

                using (ManagementObjectCollection moc = mc.GetInstances())

                {

                    int i = 0, instanceCount = moc.Count;

                    if (instanceCount > 1)

                        WriteLine("该对象共有 {0} 个实例，方括号中是其编号！", instanceCount);

                    foreach (ManagementObject mo in moc)

                    {

                        i++;

                        IEnumerable<PropertyData> properties = mo.Properties.Cast<PropertyData>();

                        //通过属性名筛选

                        if (propertyNames != null && propertyNames.Count > 0)

                            properties = properties.Where(

                                pd => propertyNames.Exists(

                                    pn => pn.Equals(pd.Name, StringComparison.OrdinalIgnoreCase)

                        ));

                        //通过属性值筛选

                        if (predicate != null)

                            properties = properties.Where(pd => pd.Value != null && predicate(pd.Value.ToString()));

                        properties = properties.ToList();

                        //输出属性字典                                            

                        if (properties.Count() > 0)

                        {

                            string prefix = instanceCount > 1 ? string.Format("{0}[{1}].", win32ClassName, i) : string.Empty;

                            foreach (PropertyData pd in properties)

                                WriteLine("{0}{1}: {2}", prefix, pd.Name, pd.Value);

                            WriteLine("查询耗时：{0} 毫秒", (DateTime.Now - start).TotalMilliseconds);

                        }

                    }

                }

            }

            catch (Exception exp)

            {

                WriteLine("查询{0}出错！\r\n异常：{1}\r\n堆栈：{2}", win32ClassName, exp.Message, exp.StackTrace);

            }

            finally

            {

                if (mc != null) mc.Dispose();

            }

        }


查询所有属性

QuerySystemInfoByWmi("Win32_ComputerSystem", null, null, null);


查询指定属性

var propertyNames = new List<string> { "Caption", "Name", "CSDVersion", "Version" };

QuerySystemInfoByWmi("Win32_OperatingSystem", propertyNames, null, null);
