我希望使一個Listener
能夠監視/跟蹤RAM的使用情況。讓一個Listerner來檢測內存使用情況
我知道,在C#中,我們可以使用
public static class PerformanceInfo
{
[DllImport("psapi.dll", SetLastError = true)]
[return: MarshalAs(UnmanagedType.Bool)]
public static extern bool GetPerformanceInfo([Out] out PerformanceInformation PerformanceInformation, [In] int Size);
[StructLayout(LayoutKind.Sequential)]
public struct PerformanceInformation
{
public int Size;
public IntPtr CommitTotal;
public IntPtr CommitLimit;
public IntPtr CommitPeak;
public IntPtr PhysicalTotal;
public IntPtr PhysicalAvailable;
public IntPtr SystemCache;
public IntPtr KernelTotal;
public IntPtr KernelPaged;
public IntPtr KernelNonPaged;
public IntPtr PageSize;
public int HandlesCount;
public int ProcessCount;
public int ThreadCount;
}
public static Int64 GetPhysicalAvailableMemoryInMiB()
{
PerformanceInformation pi = new PerformanceInformation();
if (GetPerformanceInfo(out pi, Marshal.SizeOf(pi)))
{
return Convert.ToInt64((pi.PhysicalAvailable.ToInt64() * pi.PageSize.ToInt64()/1048576));
}
else
{
return -1;
}
}
public static Int64 GetTotalMemoryInMiB()
{
PerformanceInformation pi = new PerformanceInformation();
if (GetPerformanceInfo(out pi, Marshal.SizeOf(pi)))
{
return Convert.ToInt64((pi.PhysicalTotal.ToInt64() * pi.PageSize.ToInt64()/1048576));
}
else
{
return -1;
}
}
}
}
沒有這個監聽器應該跟蹤RAM使用的每一秒,如果它比指定%年齡越大,那麼它應該Kill Some Processes
還是應該提供一些獲得工作用法通知我的應用程序(WPF應用程序)殺死一些特定的進程
怎樣才能讓一段代碼constantlr聽SYTEM,然後調用一些動作
在這方面的任何幫助將是巨大的..
