这篇“C#怎么基于JSONConvert解析json数据”文章的知识点大部分人都不太理解,所以小编给大家总结了以下内容,内容详细,步骤清晰,具有一定的借鉴价值,希望大家阅读完这篇文章能有所收获,下面我们一起来看看这篇“C#怎么基于JsonConvert解析Json数据”文章吧。
private void ParseJson() { // 解析为JObjectstring jsonStr = "{'name': 'zhangsan', 'sex': 'male', 'age': 23}";JObject jo = JsonConvert.DeserializeObject<JObject>(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;
private void ParseJson() { // 解析为Dictionary<string, object>string jsonStr = "{'name': 'zhangsan', 'sex': 'male', 'age': 23}";Dictionary<string, object> dict = JsonConvert.DeserializeObject<Dictionary<string, object>>(jsonStr);print("name=" + dict["name"] + ", sex=" + dict["sex"] + ", age=" + dict["age"]);}
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<Student>(jsonStr);print("stu=" + stu);}
private void ParseJson() { // 解析一维数组(JArray)string jsonStr = "[1, 2, 3, 4, 5]";JArray ja = JsonConvert.DeserializeObject<JArray>(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 + "]";}
private void ParseJson() { // 解析一维数组(int[])string jsonStr = "[1, 2, 3, 4, 5]";int[] arr = JsonConvert.DeserializeObject<int[]>(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 + "]";}
private void ParseJson() { // 解析一维数组(List<int>)string jsonStr = "[1, 2, 3, 4, 5]";List<int> list = JsonConvert.DeserializeObject<List<int>>(jsonStr);print(GetListString(list));} private string GetListString(List<int> 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 + "]";}
private void ParseJson() { // 解析二维数组(JArray)string jsonStr = "[[1, 2], [3, 4], [5, 6]]";JArray ja2 = JsonConvert.DeserializeObject<JArray>(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<int[][]>(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。
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<JObject>(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。
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<VecInfo>(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。
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<JArray>(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);}
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<Student[]>(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。
private void ParseJson() { // "字典数组"混合解析(List<Student>)string jsonStr = "[{'name': 'xiaomin', 'sex': 'male', 'age': 23}, {'name': 'xiaohong', 'sex': 'female', 'age': 21}]";List<Student> list = JsonConvert.DeserializeObject<List<Student>>(jsonStr);print(GetStudentListString(list));} private string GetStudentListString(List<Student> 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 + "]";}
private void ParseJson() {string jsonStr = "[{'x': 1, 'y': 2, 'z': 3}, {'x': 4, 'y': 5, 'z': 6}, {'x': 7, 'y': 8, 'z': 9}]";Vector3[] points = JsonConvert.DeserializeObject<Vector3[]>(jsonStr);print(GetVectorString(points));} private string GetVectorString(Vector3[] points) {string str = "[";if (points != null && points.Length > 0) {str += points[0];}for (int i = 1; i < points.Length; i++) {str += ", " + points[i];}return str + "]";}
2)数组格式点
private void ParseJson() {string jsonStr = "[[1, 2, 3], [4, 5, 6], [7, 8, 9]]";float[][] arr = JsonConvert.DeserializeObject<float[][]>(jsonStr);Vector3[] points = new Vector3[arr.Length];for(int i = 0; i < arr.Length; i++) {points[i] = new Vector3(arr[i][0], arr[i][1], arr[i][2]);}print(GetVectorString(points));}
说明:GetVectorString 方法同第 1)节。
private void ParseJson() { // 解析为JObjectstring jsonStr = File.ReadAllText("Assets/Scenes/Student.json", Encoding.UTF8);JObject jo = JsonConvert.DeserializeObject<JObject>(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}
