Newtonsoft.Json.dll使用

javascript json textbox string c

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

2：解析JSON字符窜

方法1：

[csharp] view plain copy print ?

1. usingNewtonsoft.Json;
2. usingSystem.Text;
4. StringBuildersb=newStringBuilder();
5. stringstr="[{ID:'1',Name:'John',Other:[{Age:'21',Sex:'0'}]},{ID:'2',Name:'Good',Other:[{Age:'36',Sex:'1'}]}]";
6. JavaScriptArrayjavascript=(JavaScriptArray)JavaScriptConvert.DeserializeObject(str);
8. for(inti=0;i<javascript.Count;i++)
9. {
10. JavaScriptObjectobj=(JavaScriptObject)javascript[i];
11. sb.Append("ID："+obj["ID"].ToString());
12. sb.Append("Name："+obj["Name"].ToString());
13. JavaScriptArrayjson=(JavaScriptArray)obj["Other"];
15. for(intj=0;j<json.Count;j++){
16. JavaScriptObjectjsonobj=(JavaScriptObject)json[j];
17. sb.Append("Age："+jsonobj["Age"].ToString());
18. sb.Append("Sex："+jsonobj["Sex"].ToString());
19. }
20. }

using Newtonsoft.Json;
using System.Text;

StringBuilder sb = new StringBuilder();
                string str = "[{ID:'1',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());
                    }
                }

方法2：不实用

[csharp] view plain copy print ?

1. stringjsonText="[{'a':'aaa','b':'bbb','c':'ccc'},{'a':'aaa2','b':'bbb2','c':'ccc2'}]";
2. JsonReaderreader=newJsonReader(newStringReader(jsonText));
4. while(reader.Read())
5. {
6. textBox1.Text+="TokenType="+reader.TokenType+"ValueType="+reader.ValueType+"Value="+reader.Value+"\r\n";
8. }

string jsonText = "[{'a':'aaa','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";

                }
