一、获取CPU使用率：
#region 获取CPU使用率 #region AIP声明
[DllImport("IpHlpApi.dll")]
extern static public uint GetIfTable(byte[] pIfTable, ref uint pdwSize, bool bOrder); [DllImport("User32")]
private extern static int GetWindow(int hWnd, int wCmd); [DllImport("User32")]
private extern static int GetWindowLongA(int hWnd, int wIndx); [DllImport("user32.dll")]
private static extern bool GetWindowText(int hWnd, StringBuilder title, int maxBufSize); [DllImport("user32", CharSet = CharSet.Auto)]
private extern static int GetWindowTextLength(IntPtr hWnd);
#endregion
public static float? GetCpuUsedRate()
{
try
{
PerformanceCounter pcCpuLoad;
pcCpuLoad = new PerformanceCounter("Processor", "% Processor Time", "_Total")
{
MachineName = "."
};
pcCpuLoad.NextValue();
Thread.Sleep();
float CpuLoad= pcCpuLoad.NextValue();
return CpuLoad;
}
catch
{
}
return ;
}
#endregion
二、获取内存使用率
其中ManagementClass类需要手动引用System.Management，然后再using System.Management。
#region 获取内存使用率
#region 可用内存 /// <summary>
/// 获取可用内存
/// </summary>
internal static long? GetMemoryAvailable()
{
long availablebytes = ;
var managementClassOs = new ManagementClass("Win32_OperatingSystem");
foreach (var managementBaseObject in managementClassOs.GetInstances())
if (managementBaseObject["FreePhysicalMemory"] != null)
availablebytes = * long.Parse(managementBaseObject["FreePhysicalMemory"].ToString());
return availablebytes / MbDiv;
} #endregion
internal static double? GetMemoryUsed()
{
float? PhysicalMemory = GetPhysicalMemory();
float? MemoryAvailable = GetMemoryAvailable();
double? MemoryUsed = (double?)(PhysicalMemory - MemoryAvailable);
double currentMemoryUsed = (double)MemoryUsed ;
return currentMemoryUsed ;
}
private static long? GetPhysicalMemory()
{
//获得物理内存
var managementClass = new ManagementClass("Win32_ComputerSystem");
var managementObjectCollection = managementClass.GetInstances();
long PhysicalMemory;
foreach (var managementBaseObject in managementObjectCollection)
if (managementBaseObject["TotalPhysicalMemory"] != null)
{
return long.Parse(managementBaseObject["TotalPhysicalMemory"].ToString())/ MbDiv;
}
return null; }
public static double? GetMemoryUsedRate()
{
float? PhysicalMemory = GetPhysicalMemory();
float? MemoryAvailable = GetMemoryAvailable();
double? MemoryUsedRate =(double?)(PhysicalMemory - MemoryAvailable)/ PhysicalMemory;
return MemoryUsedRate.HasValue ? Convert.ToDouble(MemoryUsedRate * ) : ;
}
#endregion #region 单位转换进制 private const int KbDiv = ;
private const int MbDiv = * ;
private const int GbDiv = * * ; #endregion
三、获取Mac地址
#region 获取当前活动网络MAC地址
/// <summary>
/// 获取本机MAC地址
/// </summary>
/// <returns>本机MAC地址</returns>
public static string GetMacAddress()
{
try
{
string strMac = string.Empty;
ManagementClass mc = new ManagementClass("Win32_NetworkAdapterConfiguration");
ManagementObjectCollection moc = mc.GetInstances();
foreach (ManagementObject mo in moc)
{
if ((bool)mo["IPEnabled"] == true)
{
strMac = mo["MacAddress"].ToString();
}
}
moc = null;
mc = null;
return strMac;
}
catch
{
return "unknown";
}
}
#endregion
四、获取磁盘使用率
#region 获取磁盘占用率
internal static double GetUsedDiskPercent()
{
float? usedSize = GetUsedDiskSize();
float? totalSize = GetTotalSize();
double? percent = (double?)usedSize / totalSize;
return percent.HasValue ? Convert.ToDouble(percent * ) : ;
} internal static float? GetUsedDiskSize()
{
var currentDrive = GetCurrentDrive();
float UsedDiskSize =(long)currentDrive?.TotalSize - (long)currentDrive?.TotalFreeSpace;
return UsedDiskSize / MbDiv;
} internal static float? GetTotalSize()
{
var currentDrive = GetCurrentDrive(); float TotalSize = (long)currentDrive?.TotalSize / MbDiv;
return TotalSize;
} /// <summary>
/// 获取当前执行的盘符信息
/// </summary>
/// <returns></returns>
private static DriveInfo GetCurrentDrive()
{
string path = Application.StartupPath.ToString().Substring(, );
return DriveInfo.GetDrives().FirstOrDefault<DriveInfo>(p => p.Name.Equals(path));
}
#endregion
