獲取電腦內部信息 - ComputerInfoHelper

一、代碼

　　ComputerInfoHelper.cs

    /// <summary>
    /// 電腦信息助手類
    /// </summary>
    public class ComputerInfoHelper
    {
        /// <summary>
        /// 獲取硬碟容量彙總
        /// </summary>
        public static long GetTotalDiskSize()
        {
            try
            {
                var diskDriveManagement = new ManagementClass(WmiPath.DiskDrive);
                var diskDriveManagementInstances = diskDriveManagement.GetInstances();

                return diskDriveManagementInstances.OfType<ManagementObject>()
                    .Select(managementObject => Convert.ToInt64(managementObject[ManagementBaseObjectPropertyName.Size]))
                    .Aggregate<long, long>(0, (current, diskSize) => diskSize + current);
            }
            catch(Exception e)
            {
                Console.WriteLine(e);
                throw;
            }
        }
    }

    }
}

二、測試

　　1.電腦硬碟信息

 　　2.我的電腦中的硬碟信息

 　　3.測試代碼

 　　4.輸出結果：

 　　所有硬碟及 U 盤和存儲卡，因生產廠家的計算方式和操作系統的計算方式不一樣，前者按 1MB = 1000KB 計算，後者按 1MB = 1024KB 計算，所以，實際在電腦中看到的容量會與廠商標稱的容量有一定的差異，其中規律為 1G = 0.93G (約等於)，比如 100G，實際為 100G * 0.93 = 93G ，具體容量可參考此公式計算。
