C#獲取主機信息

獲取主機信息

最近須要作一個配合集控系統收集各個終端設備的一些信息，大體須要收集終端設備的硬件信息，CPU、內存以及硬盤使用率等信息。網上查看了一番，使用WMI來獲取這些信息是最方便的。實現代碼以下：

Models.PlatformInfo platformInfo = new Models.PlatformInfo();
string query = "Select * from {0}";
///獲取操做系統數據
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"]);
}

其中能夠使用os.GetText(TextFormat.Mof);來獲取詳細的信息。
目前我查到的能夠獲取的API接口有以下：

    Win32_NetworkProtocol,
}

查詢都是一致的："Select * from {0}"
這樣就能獲取到想要獲取到的信息了。
獲取開機時間：

/// <summary>
/// 獲取開機運行時間
/// </summary>
/// <returns></returns>
public string GetRunTime()
{
    TimeSpan ts = TimeSpan.FromMilliseconds(Environment.TickCount);
    return ts.ToString();
}

獲取CPU使用率能夠使用性能計數器組件。

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") + "%";
}
