1 解析字典

        1）解析为 JObject

private void ParseJson() { // 解析为JObjectstring jsonStr = "{'name': 'zhangsan', 'sex': 'male', 'age': 23}";JObject jo = JsonConvert.DeserializeObject(jsonStr);print("name=" + jo["name"] + ", sex=" + jo["sex"] + ", age=" + jo["age"]);
}

        说明：需要使用以下命名空间：

using Newtonsoft.Json;
using Newtonsoft.Json.Linq;

        2）解析为 Dictionary

private void ParseJson() { // 解析为Dictionarystring jsonStr = "{'name': 'zhangsan', 'sex': 'male', 'age': 23}";Dictionary dict = JsonConvert.DeserializeObject>(jsonStr);print("name=" + dict["name"] + ", sex=" + dict["sex"] + ", age=" + dict["age"]);
}

         3）解析为封装类

class Student {public string name;public string sex;public int age;public override string ToString() {return "{name: " + name + ", sex: " + sex + ", age: " + age + "}";}
}private void ParseJson() { // 解析为Studentstring jsonStr = "{'name': 'zhangsan', 'sex': 'male', 'age': 23}";Student stu = JsonConvert.DeserializeObject(jsonStr);print("stu=" + stu);
}

2 解析一维数组

         1）解析为 JArray

private void ParseJson() { // 解析一维数组(JArray)string jsonStr = "[1, 2, 3, 4, 5]";JArray ja = JsonConvert.DeserializeObject(jsonStr);print(GetJArrayString(ja));
}private string GetJArrayString(JArray ja) {string str = "[";if (ja != null && ja.Count > 0) {str += ja[0];}for (int i = 1; i < ja.Count; i++) {str += ", " + ja[i];}return str + "]";
}

        2）解析为数组

private void ParseJson() { // 解析一维数组(int[])string jsonStr = "[1, 2, 3, 4, 5]";int[] arr = JsonConvert.DeserializeObject(jsonStr);print(GetArrString(arr));
}private string GetArrString(int[] arr) {string str = "[";if (arr != null && arr.Length > 0) {str += arr[0];}for (int i = 1; i < arr.Length; i++) {str += ", " + arr[i];}return str + "]";
}

        3）解析为列表

private void ParseJson() { // 解析一维数组(List)string jsonStr = "[1, 2, 3, 4, 5]";List list = JsonConvert.DeserializeObject>(jsonStr);print(GetListString(list));
}private string GetListString(List list) {string str = "[";if (list != null && list.Count > 0) {str += list[0];}for (int i = 1; i < list.Count; i++) {str += ", " + list[i];}return str + "]";
}

3 解析二维数组

         1）解析为 JArray

private void ParseJson() { // 解析二维数组(JArray)string jsonStr = "[[1, 2], [3, 4], [5, 6]]";JArray ja2 = JsonConvert.DeserializeObject(jsonStr);print(GetJArrayString2(ja2));
}private string GetJArrayString2(JArray ja2) {string str = "[";if (ja2 != null && ja2.Count > 0) {str += GetJArrayString((JArray)ja2[0]);}for (int i = 1; i < ja2.Count; i++) {str += ", " + GetJArrayString((JArray)ja2[i]);}return str + "]";
}

        说明：GetJArrayString 方法见 2 1）节。 

         2）解析为二维数组

private void ParseJson() { // 解析二维数组(int[][])string jsonStr = "[[1, 2], [3, 4], [5, 6]]";int[][] arr = JsonConvert.DeserializeObject(jsonStr);print(GetArrString2(arr));
}private string GetArrString2(int[][] arr) {string str = "[";if (arr != null && arr.Length > 0) {str += GetArrString(arr[0]);}for (int i = 1; i < arr.Length; i++) {str += ", " + GetArrString(arr[i]);}return str + "]";
}

        说明：GetArrString 方法见 2 2）节。

4 解析数组字典

        1）解析为 JObject-JArray

private void ParseJson() { // "数组字典"混合解析(JObject-JArray)string jsonStr = "{'vec1': [1, 2, 3, 4], 'vec2': [[1, 2], [3, 4], [5, 6]]}";JObject jo = JsonConvert.DeserializeObject(jsonStr);print("vec1=" + GetJArrayString((JArray) jo["vec1"]) + ", vec2=" + GetJArrayString2((JArray) jo["vec2"]));
}

        说明： GetJArrayString 方法见 2 1）节，GetJArrayString2 方法见 3 1）节。

        2）解析为封装类

class VecInfo {public int[] vec1;public int[][] vec2;
}private void ParseJson() { // "数组字典"混合解析(封装类)string jsonStr = "{'vec1': [1, 2, 3, 4], 'vec2': [[1, 2], [3, 4], [5, 6]]}";VecInfo vecInfo = JsonConvert.DeserializeObject(jsonStr);print("vec1=" + GetArrString(vecInfo.vec1) + ", vec2=" + GetArrString2(vecInfo.vec2));
}

        说明： GetArrString 方法见 2 2）节，GetArrString2 方法见 3 2）节。

5 解析字典数组

        1）解析为 JArray-JObject

private void ParseJson() { // "字典数组"混合解析(JArray-JObject)string jsonStr = "[{'name': 'xiaomin', 'sex': 'male', 'age': 23}, {'name': 'xiaohong', 'sex': 'female', 'age': 21}]";JArray ja = JsonConvert.DeserializeObject(jsonStr);string str = "[";if (ja.Count > 0) {str += "{name: " + ja[0]["name"] + ", sex: " + ja[0]["sex"] + ", age: " + ja[0]["age"] + "}";}for (int i = 1; i < ja.Count; i++) {str += ", {name: " + ja[i]["name"] + ", sex: " + ja[i]["sex"] + ", age: " + ja[i]["age"] + "}";}str += "]";print(str);
}

         2）解析为数组封装类

private void ParseJson() { // "字典数组"混合解析(Student[])string jsonStr = "[{'name': 'xiaomin', 'sex': 'male', 'age': 23}, {'name': 'xiaohong', 'sex': 'female', 'age': 21}]";Student[] stus = JsonConvert.DeserializeObject(jsonStr);print(GetStudentArrString(stus));
}private string GetStudentArrString(Student[] stus) {string str = "[";if (stus != null && stus.Length > 0) {str += stus[0];}for (int i = 1; i < stus.Length; i++) {str += ", " + stus[i];}return str + "]";
}

        说明：Student 类见 1 3）节。

         3）解析为列表封装类

private void ParseJson() { // "字典数组"混合解析(List)string jsonStr = "[{'name': 'xiaomin', 'sex': 'male', 'age': 23}, {'name': 'xiaohong', 'sex': 'female', 'age': 21}]";List list = JsonConvert.DeserializeObject>(jsonStr);print(GetStudentListString(list));
}private string GetStudentListString(List list) {string str = "[";if (list != null && list.Count > 0) {str += list[0];}for (int i = 1; i < list.Count; i++) {str += ", " + list[i];}return str + "]";
}

6 从文件中解析 

private void ParseJson() { // 解析为JObjectstring jsonStr = File.ReadAllText("Assets/Scenes/Student.json", Encoding.UTF8);JObject jo = JsonConvert.DeserializeObject(jsonStr);print("name=" + jo["name"] + ", sex=" + jo["sex"] + ", age=" + jo["age"]);
}

        说明：File 和  Encoding.UTF8 需要引入命名空间 System.IO、System.Text。

        Student.json

{'name': 'zhangsan', 'sex': 'male', 'age': 23}
