在研发之余，将做工程过程中比较重要的一些内容备份一下，如下的内容内容是关于C# 自定义堆栈进行回文检测的内容，希望对各朋友也有用。

using System;

namespace CStack

string ch;          string word = "上海自来水来自海上";          bool isPalindrome = true;          for (int x = 0; x < word.Length; x++)          {              alist.Push(word.Substring(x,1));          }          int pos = 0;          while (alist.Count > 0)          {              ch = alist.Pop().ToString();              if (ch !=word.Substring(pos,1))              {                  isPalindrome = false;                  break;              }              pos++;          }          Console.WriteLine(isPalindrome);      }  }  public class CStack  {      private int p_index;      private ArrayList list;      public CStack()      {          list = new ArrayList();          p_index = -1;      }      public int Count      {          get { return list.Count; }      }      public void Push(object item)      {          list.Add(item);          p_index++;      }      public object Pop()      {          if (0 > p_index)          {              return null;          }          object obj = list[p_index];          list.RemoveAt(p_index);          p_index--;          return obj;      }       public void Clear()      {          list.Clear();          p_index = -1;      }      public object Peek()      {          if (p_index < 0)          {              return null;          }          return list[p_index];      }  }
