我希望做一个Listener
观察/跟踪 RAM 使用情况。
我知道在 C# 中我们可以使用
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;
}
}
}
}
不,此侦听器应每秒跟踪 RAM 使用情况,如果它大于指定的 %age,则它应该Kill Some Processes
或应该向我的应用程序(WPF 应用程序)提供一些通知以终止某些特定进程
我怎样才能让一段代码不断地听系统,然后调用一些动作
在这方面的任何帮助都会很棒..
