C#的一个小函数来计算一个运算使用的时间和内存

Contents

 

如下，分别计算时间和内存。

public static double TimeWatcher(Action action)
{
    System.Diagnostics.Stopwatch watch = new System.Diagnostics.Stopwatch();
    watch.Start();
    action();
    watch.Stop();
    var useTime = (double) watch.ElapsedMilliseconds/1000;
    return useTime;
}

public static long MemoryWatcher(Action action)
{
    long start = GC.GetTotalMemory(true);
    action();
    GC.Collect();
    GC.WaitForFullGCComplete();
    long end = GC.GetTotalMemory(true);
    long useMemory = (end - start)/(1024*1024);
    return useMemory;
}
