我想在c#中尝试指针运算.我使用了一个asp.net网络应用程序,期望它是无论是这个还是一个控制台应用程序.

这是我试过的:

public class memorytest
{
    public class Sample
    {
        public int A;
        public int B;
        public int C;
        public int D;
    }

   public static unsafe void Main()
   {
    Sample s = new Sample {A = 1, B = 2, C = 3, D = 4};
    int a = 1;
    int b = 2;
    int* pA = &a;
    int* pB = &b;
    Debug.WriteLine("{0:x16}",* pB);
    Debug.WriteLine("{0:x16}",*(pB - 1));
    Debug.WriteLine(*pA);
    Debug.WriteLine("{0:x16}",*(pB - 2));
    }

}

结果是这样的:

0000000000000002,0000000004b5ca00,10000004b5c9fc,

我显然希望第二个是数字1.有人理解这一点吗？
