三平流浪记

从今天开始学习.net！

今天花了一下午时间学了.net

这是笔记！

Convert.ToInt32

ToString放在前面或者后面

读取二维数组
string[,] arr = new string[2, 4];
         arr[0, 0] = “sanp”;
         arr[0, 1] = “男”;
         arr[0, 2] = “学生”;
         arr[0, 3] = “21″;
         arr[1, 0] = “test”;
         arr[1, 1] = “女”;
         arr[1, 2] = “工程师”;
         arr[1, 3] = “25″;

         Response.Write(“<br>” + arr.Rank);
         Response.Write(“<br>”+arr.GetUpperBound(arr.Rank-1));

         //利用数组循环读出多维数组
         for (int i = 0; i < arr.Rank; i++)
         {
             for (int j = 0; j <= arr.GetUpperBound(arr.Rank – 1); j++)
             {
                 Response.Write(“<br>” + arr[i, j].ToString());
             }
         }

结构与枚举
struct
enum

泛型
string[] arr = new string[] {“1abcd”,”2afds”,”3adfc”,”4fcvd”,”5aewq”,”6aiud”};
         foreach(string r in arr)
         {
             if (r.Contains(“a”))
             {
                 Response.Write(r.ToString() + “<br>”);
             }
         }

运算符重载
cookie
httpcookie
request.cookie

visual studio 2005这个IDE真不错！
