2、方法调用

string GetCPUNumber = Computer.GetCPUNumber();  //获取CPU号码
            string CpuInfo = Computer.CpuInfo();  //获取CPU信息

            string GetHardDiskNumber = Computer.GetHardDiskNumber();  //获取硬盘号码
            string HardDiskInfo = Computer.HardDiskInfo();  //获取硬盘信息

            string GetMemoryNumber = Computer.GetMemoryNumber();   //获取内存编号
            string MemoryInfo = Computer.MemoryInfo();  //获取内存信息

            string OSInfo = Computer.OSInfo();    //获取操作系统信息

            StringBuilder sb = new StringBuilder();
