public static extern int SetProcessWorkingSetSize(IntPtr process, int minSize, int maxSize);

/// <summary>

/// 释放内存

public static void ClearMemory()

{

    GC.Collect();

    GC.WaitForPendingFinalizers();

    if (Environment.OSVersion.Platform == PlatformID.Win32NT)

    {

        App.SetProcessWorkingSetSize(System.Diagnostics.Process.GetCurrentProcess().Handle, -1, -1);

    }

}
