AggressiveInlining何时适用于简单的包装

当我简单地包装一个名为的数据结构时，我看不到AggressiveInlining的效果

例如：

public class WList
{
   //made static just to check inlining
   //otherwise inlining might not kick in since 'this' keyword will disallow it
   static System.Collections.ArrayList list;
   [MethodImpl(MethodImplOptions.AggressiveInlining)]
   public override void Put(object item)
   {
       WList.list.Add(item);
   }
}

然后做这个

    //Add 1000000 number of items in the list
    //Run this test many times 
    for (int j = 0; j < 100; j++)
    {
        Stopwatch sw = new Stopwatch();
        sw.Start();
        for (int i = 0; i < length; i++)
        {
            //ADD ITEMS IN A SIMPLE ARRAY LIST
            arraylist.Add(emptyobject);
        }
        sw.Stop();
        //clear the list
    }
    //Do similar test on wrapper
    for (int j = 0; j < 100; j++)
    {
        Stopwatch sw = new Stopwatch();
        sw.Start();
        for (int i = 0; i < length; i++)
        {
            //ADD ITEMS IN ARRAY LIST THROUGH WRAPPER
            wrapperList.Put(emptyobject);
        }
        sw.Stop();
        //clear the list
    }

Inlinig基本上应该打开函数并将内部代码放在外部，但我从包装机上得到的号码比直拨电话要慢。

如果使用Hastable或使用get调用而不是add，则数字保持不变。

函数调用的性能成本仍然存在。
