通过C# 来读取PC 的MotherBoard 上的信息，如 产品名称，制造商，版本等，方法如下：

1. Reference中添加 System.Management，并在头文件中引入该 Assemble
   
2. 添加对应的类，并进行使用，如下实例：

public static class MotherBoardInfo
    {
        private static ManagementObjectSearcher baseboardSearcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_BaseBoard");
        private static ManagementObjectSearcher motherboardSearcher = new ManagementObjectSearcher("root\\CIMV2", "SELECT * FROM Win32_MotherboardDevice");

        public static string Manufacturer
        {
            get
            {
                try
                {
                    foreach(ManagementObject obj in motherboardSearcher.Get())
                    {
                        return obj["Manufacturer"].ToString();
                    }
                    return "";
                }
                catch(Exception exp)
                {
                    return "";
                }

            }
        }

        public static string ModelName
        {
            get
            {
                try
                {
                    foreach(ManagementObject obj in motherboardSearcher.Get())
                    {
                        return obj["Model"].ToString();
                    }
                    return "";
                }
                catch(Exception exp)
                {
                    return "";
                }
            }
        }

        public static string ProductName
        {
            get
            {
                try
                {
                    foreach(ManagementObject obj in baseboardSearcher.Get())
                    {
                        return obj["Product"].ToString();
                    }
                    return "";
                }
                catch(Exception exp)
                {
                    return "";
                }
            }
        }
    }
