SetProcessWorkingSetSize减少内存占用

系统启动起来以后,内存占用越来越大,使用析构函数、GC.Collect什么的也不见效果,后来查了好久,找到了个办法,就是使用 SetProcessWorkingSetSize函数。这个函数是Windows API 函数。下面是使用的方法:

[System.Runtime.InteropServices.DllImportAttribute("kernel32.dll", EntryPoint = "SetProcessWorkingSetSize", ExactSpelling = true, CharSet =
System.Runtime.InteropServices.CharSet.Ansi, SetLastError = true)]
private static extern int SetProcessWorkingSetSize(IntPtr process, int minimumWorkingSetSize, int maximumWorkingSetSize);

public void Dispose()
{
    GC.Collect();
    GC.SuppressFinalize(this);

    if (Environment.OSVersion.Platform == PlatformID.Win32NT)
    {
        SetProcessWorkingSetSize(System.Diagnostics.Process.GetCurrentProcess().Handle, -1, -1);
    }
}

使用这个函数也会有些问题,具体的可以参见:
