C#获取电脑型号、系统版本、内存和硬盘大小、CPU信息

C#获取电脑型号、系统版本、内存和硬盘大小、CPU信息

🗨

通过调用windows api的方式,可以获取电脑的相关硬件信息。

方法

可以通过在powershell中 通过下面的命令进行查询,然后可以通过c#调用获取需要的信息。

gwmi + windows api 

如图所示

对应的c#代码为

复制代码
  /// <summary>
        /// 获取硬盘容量
        /// </summary>
        public string GetDiskSize()
        {
            string result = string.Empty;
            StringBuilder sb = new StringBuilder();
            try
            {
                string hdId = string.Empty;
                ManagementClass hardDisk = new ManagementClass(WindowsAPIType.win32_DiskDrive.ToString());
                ManagementObjectCollection hardDiskC = hardDisk.GetInstances();
                foreach (ManagementObject m in hardDiskC)
                {
                    long capacity = Convert.ToInt64(m[WindowsAPIKeys.Size.ToString()].ToString());
                    sb.Append(CommonUtlity.ToGB(capacity, 1000.0) + "+");
                }
                result = sb.ToString().TrimEnd('+');
            }
            catch
            {

            }
            return result;
        }

这里只是枚举了部分api,有兴趣的可以查看其它的windows api 并通过power shell查看,然后转化为c# 代码即可。

这里需要注意,硬盘容量在转化的时候需要除以1000,而不是1024.但内存是需要除以1024的,这点需要注意。

转化方法:

复制代码
   /// <summary>  
        /// 将字节转换为GB
        /// </summary>  
        /// <param name="size">字节值</param>  
        /// <param name="mod">除数,硬盘除以1000,内存除以1024</param>  
        /// <returns></returns>  
        public static string ToGB(double size, double mod)
        {
            String[] units = new String[] { "B", "KB", "MB", "GB", "TB", "PB" };
            int i = 0;
            while (size >= mod)
            {
                size /= mod;
                i++;
            }
            return Math.Round(size) + units[i];
        }
