Newtonsoft.Json解析json字符串和写json字符串

//using Newtonsoft.Json;        StringBuilder sb = new StringBuilder();        string str = "[{ID:'1',Name:'zhangsan',Other:[{Age:'111'}]}]";        JavaScriptArray javascript = (JavaScriptArray)JavaScriptConvert.DeserializeObject(str);        if (javascript.Count > 0)        {            JavaScriptObject obj = (JavaScriptObject)javascript[0];            sb.Append("ID：" + obj["ID"].ToString() + "<br/>");            sb.Append("Name：" + obj["Name"].ToString() + "<br/>");            JavaScriptArray json = (JavaScriptArray)obj["Other"];            if (json.Count > 0)            {                JavaScriptObject jsonobj = (JavaScriptObject)json[0];                sb.Append("Age：" + jsonobj["Age"].ToString());            }        }        Response.Write(sb.ToString());

 

//有时候版本不同上面的有错误，可以试试这种StringBuilder sb = new StringBuilder();    protected void Page_Load(object sender, EventArgs e)    {        string jsontext = "[{ID:'1',Name:'zhangsan',Other:[{Age:'111'}]}]";        Newtonsoft.Json.Linq.JArray ja = (Newtonsoft.Json.Linq.JArray)Newtonsoft.Json.JsonConvert.DeserializeObject(jsontext);        foreach (Newtonsoft.Json.Linq.JObject item in ja)        {            string aa = item["Name"].ToString();            Newtonsoft.Json.Linq.JArray ja0 = (Newtonsoft.Json.Linq.JArray)item["Other"];            foreach (Newtonsoft.Json.Linq.JObject item0 in ja0)            {                string bb = item0["Age"].ToString();            }        }

 

StringWriter sw = new StringWriter();        JsonWriter writer = new JsonWriter(sw);//如果报错则使用JsonWriter writer = new JsonTextWriter(sw);        writer.WriteStartArray();        writer.WriteValue("JSON!");        writer.WriteValue(1);        writer.WriteValue(true);        writer.WriteStartObject();        writer.WritePropertyName("property");        writer.WriteValue("value");        writer.WriteEndObject();        writer.WriteStartObject();        writer.WritePropertyName("data");        writer.WriteValue(_str);        writer.WriteEndObject();        writer.WriteEndArray();        writer.Flush();        string jsonText = sw.GetStringBuilder().ToString();        Response.Write(jsonText);
