关于ArrayList、Ienumerator？

解决方法：

ArrayList a=new ArrayList();

              string s1="aaaaa";

              string s2="bbbbb";

              string s3="ccccc";

              int i1=1;

              int i2=2;

              int i3=3;

 

              a.Add(s1);

              a.Add(s2);

              a.Add(i1);

              a.Add(i2);   

              a.Add(i3);

              a.Add(s3);

 

              IEnumerator ie=a.GetEnumerator();

              while(ie.MoveNext())

              {

                   string s=ie.Current.ToString();

                   Response.Write(s+Environment.NewLine);

              }
