c# 获取操作系统的硬件信息

c# 获取系统本身硬件的信息

需要添加 System.Management 程序集

1. 获取操作系统名称

ManagementClass manag = new ManagementClass("Win32_OperatingSystem");
ManagementObjectCollection managCollection = manag.GetInstances();
foreach (ManagementObject m in managCollection)
{
　　　　Console.WriteLine(m["Name"].ToString(); 
　　　　break; 
}

　　2. 获取CPU信息

ManagementClass mcCPU = new ManagementClass("Win32_Processor");
ManagementObjectCollection mocCPU = mcCPU.GetInstances();
foreach (ManagementObject m in mocCPU)
{
       Console.WriteLine(m["Name"].ToString());
       break;
}

　　3. 获取CPU核心数量

int coreCount = 0;
foreach (var item in new System.Management.ManagementObjectSearcher("Select * from Win32_Processor ").Get())
{
       coreCount += int.Parse(item["NumberOfCores"].ToString());
}

Console.WriteLine(coreCount.ToString() + "核");

　　4. 获取系统内存大小

ManagementObjectSearcher searcher = new ManagementObjectSearcher();   //用于查询一些如系统信息的管理对象
searcher.Query = new SelectQuery("Win32_PhysicalMemory", "", new string[] { "Capacity" });//设置查询条件
ManagementObjectCollection collection = searcher.Get();   //获取内存容量 
ManagementObjectCollection.ManagementObjectEnumerator em = collection.GetEnumerator();
long capacity = 0;
while (em.MoveNext())
{
    ManagementBaseObject baseObj = em.Current;
    if (baseObj.Properties["Capacity"].Value != null)
    {
        capacity += long.Parse(baseObj.Properties["Capacity"].Value.ToString());
    }
}
Console.WriteLine(capacity / 1024 / 1024 / 1024 + "GB");

　　4. 获取硬盘空间

System.IO.DriveInfo[] drives = System.IO.DriveInfo.GetDrives();
long totalFreeSpace = 0;
long totalDiskSize = 0;
foreach (var drive in drives)
{
    if (drive.IsReady)  //判断代码运行时 磁盘是可操作作态 
    {
        totalFreeSpace += drive.AvailableFreeSpace;
        totalDiskSize += drive.TotalSize;
    }
}
Console.WriteLine(string.Format("总容量：{0} 剩余：{1}", totalDiskSize / 1024 / 1024 / 1024 + "GB", totalFreeSpace / 1024 / 1024 / 1024 + "GB"));

　　5. 获取屏幕分辨率

ManagementClass manage = new ManagementClass("Win32_DesktopMonitor");
ManagementObjectCollection manageCollection = manage.GetInstances();
foreach (ManagementObject m in manageCollection)
{
    Console.WriteLine(m["ScreenWidth"].ToString() + "*" + m["ScreenHeight"].ToString());
    break;
}

　　6. 获取显卡芯片名称 与 显存大小

ManagementClass manage = new ManagementClass("Win32_VideoController");
ManagementObjectCollection manageCollection = manage.GetInstances();
foreach (ManagementObject m in manageCollection)
{
    Console.WriteLine(m["VideoProcessor"].ToString().Replace("Family", ""));
    Console.WriteLine((Convert.ToInt64(m["AdapterRAM"]) / 1024 / 1024 / 1024) + "GB" );
    break;
}
