最好能写注释 发给完整的版本最好

Answer 1

http://bbs.csdn.net/topics/390179955以前回答过。不可能为所有相似的问题都一一给出详细的代码还有注释。

Answer 2

MatchCollection matches=Regex.Matches(strInput,"\"(\w+)\"":\[\{\"(\w+)\":\"(\w+)\",\"(\w+)\":\"(\w+)\",\"(\w+)\":\"(\w+)\"\},\{\"(\w+)\":\"(\w+)\",\"(\w+)\":\"(\w+)\",\"(\w+)\":\"(\w+)\"\},\{\"(\w+)\":\"(\w+)\",\"(\w+)\":\"(\w+)\",\"(\w+)\":\"(\w+)\"\}\]);
//matches里面的数据就是了

Answer 3

JavaScriptSerializer().Deserialize<A>(jsondata)

Answer 4

再帮写一个吧  谢谢啦   这个JSON我真是搞不定了！

Answer 5

          /// <summary>  根据Json返回DateTable,JSON数据格式如:           
         /// {table:[{column1:1,column2:2,column3:3},{column1:1,column2:2,column3:3}]}           
         /// </summary>           
         /// <param name="strJson">Json字符串</param>           
         /// <returns></returns>          
        public static DataTable JsonToDataTable(string strJson)
        {
            //取出表名               
            var rg = new Regex(@"(?<={)[^:]+(?=:\[)", RegexOptions.IgnoreCase);
            string strName = rg.Match(strJson).Value;
            DataTable tb = null;
            //去除表名               
            strJson = strJson.Substring(strJson.IndexOf("[") + 1);
            strJson = strJson.Substring(0, strJson.IndexOf("]"));
            //获取数据               
            rg = new Regex(@"(?<={)[^}]+(?=})");
            MatchCollection mc = rg.Matches(strJson);
            for (int i = 0; i < mc.Count; i++)
            {
                string strRow = mc[i].Value;
                string[] strRows = strRow.Split(',');
                //创建表                  
                if (tb == null)
                {
                    tb = new DataTable();
                    tb.TableName = strName;
                    foreach (string str in strRows)
                    {
                        var dc = new DataColumn();
                        string[] strCell = str.Split(':');
                        dc.ColumnName = strCell[0];
                        tb.Columns.Add(dc);
                    }
                    tb.AcceptChanges();
                }
                //增加内容                  
                DataRow dr = tb.NewRow();
                for (int r = 0; r < strRows.Length; r++)
                {
                    dr[r] = strRows[r].Split(':')[1].Trim().Replace("，", ",").Replace("：", ":").Replace("\"", "");
                }
                tb.Rows.Add(dr);
                tb.AcceptChanges();
            }
            return tb;
        }

Answer 6

找Newtonsoft.Json.dll
引用
Newtonsoft.Json.Linq

Answer 7

string p = HttpContext.Current.Server.MapPath(@"~/daxue.txt");
            var txt1 = File.ReadAllLines(p, Encoding.GetEncoding("GB2312"));//读取txt
            string con = txt1.FirstOrDefault();
            JavaScriptSerializer jss = new JavaScriptSerializer();
            List<country> langs = jss.Deserialize<List<country>>(con);
            foreach (country m in langs)
            {
                try
                {
                    object[] shengs = (object[])m.provs;
                    foreach (object sheng in shengs)
                    {
                        Dictionary<string, object> sh = (Dictionary<string, object>)sheng;
                        //解析大学
                        object[] daxues = (object[])sh["univs"];
                        foreach (object daxue in daxues)
                        {
                            Dictionary<string, object> dx = (Dictionary<string, object>)daxue;
                            Response.Write(m.name + "$" + sh["name"].ToString() + "$" + dx["name"].ToString() + "<br/>");
                        }
                    }
                }
                catch (Exception ex)
                {
                    object[] daxues = (object[])m.univs;
                    foreach (object daxue in daxues)

                        Response.Write(m.name + "$-$" + dx["name"].ToString() + "<br/>");
                    }
                    //Response.Write(ex.Message + "<br/>");
                }            }
        }        class country

            public string id { get; set; }
            public string name { get; set; }

            public object univs { get; set; }        }
这是我前几天，解析人人网大学校名数据的代码，你可以参考下，
大体思路是，按照数据格式写一个类，然后反序列化JSON
