1：Newtonsoft.Json.dll 下载  http://json.codeplex.com/

2：解析JSON字符窜

方法1：

using Newtonsoft.Json;
using System.Text;

StringBuilder sb = new StringBuilder();
                string str = "[{ID:'1',Name:'John',Other:[{Age:'21',Sex:'0'}]},{ID:'2',Name:'Good',Other:[{Age:'36',Sex:'1'}]}]";
                JavaScriptArray javascript = (JavaScriptArray)JavaScriptConvert.DeserializeObject(str);

                for (int i = 0; i < javascript.Count; i++ )
                {
                    JavaScriptObject obj = (JavaScriptObject)javascript[i];
                    sb.Append("ID：" + obj["ID"].ToString());
                    sb.Append("Name：" + obj["Name"].ToString());
                    JavaScriptArray json = (JavaScriptArray)obj["Other"];

                    for (int j = 0; j < json.Count; j++){
                        JavaScriptObject jsonobj = (JavaScriptObject)json[j];
                        sb.Append("Age：" + jsonobj["Age"].ToString());
                        sb.Append("Sex：" + jsonobj["Sex"].ToString());
                    }
                }

string jsonText = "[{'a':'aaa','b':'bbb','c':'ccc'},{'a':'aaa2','b':'bbb2','c':'ccc2'}]";
JsonReader reader = new JsonReader(new StringReader(jsonText));

                while (reader.Read())
                {
                   textBox1.Text += "TokenType = " + reader.TokenType + "   ValueType =  " + reader.ValueType + "   Value = " + reader.Value + "\r\n";

                }
