C#获取主机信息

获取主机信息

最近需要做一个配合集控系统收集各个终端设备的一些信息，大致需要收集终端设备的硬件信息，CPU、内存以及硬盘使用率等信息。网上查看了一番，使用WMI来获取这些信息是最方便的。实现代码如下：

 Models.PlatformInfo platformInfo = new Models.PlatformInfo();
string query = "Select * from {0}";
///获取操作系统数据
SelectQuery queryOS = new SelectQuery(string.Format(query, WindowAPIType.Win32_OperatingSystem));
ManagementObjectSearcher searcher = new ManagementObjectSearcher(queryOS);
foreach (ManagementBaseObject os in searcher.Get())
{
    platformInfo.Version = Convert.ToString(os["Version"]);
    platformInfo.Caption = Convert.ToString(os["Caption"]);
    platformInfo.SerialNumber = Convert.ToString(os["SerialNumber"]);
    platformInfo.SystemDirectory = Convert.ToString(os["SystemDirectory"]);
    platformInfo.OSArchitecture = Convert.ToString(os["OSArchitecture"]);
    platformInfo.InstallDate = Convert.ToString(os["InstallDate"]);
    platformInfo.Organization = Convert.ToString(os["Organization"]);
}

其中可以使用os.GetText(TextFormat.Mof);来获取详细的信息。
目前我查到的可以获取的API接口有如下：

    Win32_NetworkProtocol,
}

查询都是一致的："Select * from {0}"
这样就能获取到想要获取到的信息了。
获取开机时间：

/// <summary>
/// 获取开机运行时间
/// </summary>
/// <returns></returns>
public string GetRunTime()
{
    TimeSpan ts = TimeSpan.FromMilliseconds(Environment.TickCount);
    return ts.ToString();
}

获取CPU使用率可以使用性能计数器组件。

private PerformanceCounter performance = new PerformanceCounter("Processor", "% Processor Time", "_Total", true);

this.performance.MachineName = ".";
this.performance.NextValue();

/// <summary>
/// CPU使用率
/// </summary>
/// <returns></returns>
public string GetCPU()
{
    return this.performance.NextValue().ToString("F1") + "%";
}
