在C＃中反序列化JSON数组（或列表）

这是基本代码：

public static string DeserializeNames() { jsonData = "{\"name\":[{\"last\":\"Smith\"},{\"last\":\"Doe\"}]}"; JavaScriptSerializer ser = new JavaScriptSerializer(); nameList myNames = ser.Deserialize(jsonData); return ser.Serialize(myNames); } //Class descriptions public class name { public string last { get; set; } } public class nameList { public List { get; set; } } 

我试过了：

 nameList myNames = ser.Deserialize(jsonData); 

和：

 List myNames = ser.Deserialize<List>(jsonData); 

并且都不起作用。 有人有主意吗？

Answer 1

这段代码适合我：

 using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Web.Script.Serialization; namespace Json { class Program { static void Main(string[] args) { Console.WriteLine(DeserializeNames()); Console.ReadLine(); } public static string DeserializeNames() { var jsonData = "{\"name\":[{\"last\":\"Smith\"},{\"last\":\"Doe\"}]}"; JavaScriptSerializer ser = new JavaScriptSerializer(); nameList myNames = ser.Deserialize(jsonData); return ser.Serialize(myNames); } //Class descriptions public class name { public string last { get; set; } } public class nameList { public List name { get; set; } } } } 

Answer 2

从这里下载Json.NET http://james.newtonking.com/projects/json-net.aspx

 name deserializedName = JsonConvert.DeserializeObject(jsonData); 

Answer 3

我遇到了类似的问题，并通过理解asp.net C＃中的类来解决

我想阅读以下JSON字符串：

 [ { "resultList": [ { "channelType": "", "duration": "2:29:30", "episodeno": 0, "genre": "Drama", "genreList": [ "Drama" ], "genres": [ { "personName": "Drama" } ], "id": 1204, "language": "Hindi", "name": "The Great Target", "productId": 1204, "productMasterId": 1203, "productMasterName": "The Great Target", "productName": "The Great Target", "productTypeId": 1, "productTypeName": "Movie", "rating": 3, "releaseyear": "2005", "showGoodName": "Movies ", "views": 8333 }, { "channelType": "", "duration": "2:30:30", "episodeno": 0, "genre": "Romance", "genreList": [ "Romance" ], "genres": [ { "personName": "Romance" } ], "id": 1144, "language": "Hindi", "name": "Mere Sapnon Ki Rani", "productId": 1144, "productMasterId": 1143, "productMasterName": "Mere Sapnon Ki Rani", "productName": "Mere Sapnon Ki Rani", "productTypeId": 1, "productTypeName": "Movie", "rating": 3, "releaseyear": "1997", "showGoodName": "Movies ", "views": 6482 }, { "channelType": "", "duration": "2:34:07", "episodeno": 0, "genre": "Drama", "genreList": [ "Drama" ], "genres": [ { "personName": "Drama" } ], "id": 1520, "language": "Telugu", "name": "Satyameva Jayathe", "productId": 1520, "productMasterId": 1519, "productMasterName": "Satyameva Jayathe", "productName": "Satyameva Jayathe", "productTypeId": 1, "productTypeName": "Movie", "rating": 3, "releaseyear": "2004", "showGoodName": "Movies ", "views": 9910 } ], "resultSize": 1171, "pageIndex": "1" } ]

我的asp.net c＃代码如下所示

首先，在Web应用程序的APP_Code文件夹中创建Class3.cs页面

 using System; using System.Data; using System.Configuration; using System.Web; using System.Web.Security; using System.Web.UI; using System.Web.UI.WebControls; using System.Web.UI.WebControls.WebParts; using System.Web.UI.HtmlControls; using System.Collections; using System.Text; using System.IO; using System.Web.Script.Serialization; using System.Collections.Generic; /// 
 /// Summary description for Class3 /// 
 public class Class3 { public List ResultList_Main { get; set; } public class ListWrapper_Main { public List ResultList { get; set; } public string resultSize { get; set; } public string pageIndex { get; set; } } public class ListWrapper { public string channelType { get; set; } public string duration { get; set; } public int episodeno { get; set; } public string genre { get; set; } public string[] genreList { get; set; } public List genres { get; set; } public int id { get; set; } public string imageUrl { get; set; } //public string imageurl { get; set; } public string language { get; set; } public string name { get; set; } public int productId { get; set; } public int productMasterId { get; set; } public string productMasterName { get; set; } public string productName { get; set; } public int productTypeId { get; set; } public string productTypeName { get; set; } public decimal rating { get; set; } public string releaseYear { get; set; } //public string releaseyear { get; set; } public string showGoodName { get; set; } public string views { get; set; } } public class genres_cls { public string personName { get; set; } } }

然后，浏览器页面读取上面列出的字符串/ JSON字符串并显示/反序列化JSON对象并显示数据

 JavaScriptSerializer ser = new JavaScriptSerializer(); string final_sb = sb.ToString(); List movieInfos = ser.Deserialize>(final_sb.ToString()); foreach (var itemdetail in movieInfos) { foreach (var itemdetail2 in itemdetail.ResultList) { Response.Write("channelType=" + itemdetail2.channelType + "
"); Response.Write("duration=" + itemdetail2.duration + "
"); Response.Write("episodeno=" + itemdetail2.episodeno + "
"); Response.Write("genre=" + itemdetail2.genre + "
"); string[] genreList_arr = itemdetail2.genreList; for (int i = 0; i < genreList_arr.Length; i++) Response.Write("genreList1=" + genreList_arr[i].ToString() + "
"); foreach (var genres1 in itemdetail2.genres) { Response.Write("genres1=" + genres1.personName + "
"); } Response.Write("id=" + itemdetail2.id + "
"); Response.Write("imageUrl=" + itemdetail2.imageUrl + "
"); //Response.Write("imageurl=" + itemdetail2.imageurl + "
"); Response.Write("language=" + itemdetail2.language + "
"); Response.Write("name=" + itemdetail2.name + "
"); Response.Write("productId=" + itemdetail2.productId + "
"); Response.Write("productMasterId=" + itemdetail2.productMasterId + "
"); Response.Write("productMasterName=" + itemdetail2.productMasterName + "
"); Response.Write("productName=" + itemdetail2.productName + "
"); Response.Write("productTypeId=" + itemdetail2.productTypeId + "
"); Response.Write("productTypeName=" + itemdetail2.productTypeName + "
"); Response.Write("rating=" + itemdetail2.rating + "
"); Response.Write("releaseYear=" + itemdetail2.releaseYear + "
"); //Response.Write("releaseyear=" + itemdetail2.releaseyear + "
"); Response.Write("showGoodName=" + itemdetail2.showGoodName + "
"); Response.Write("views=" + itemdetail2.views + "

"); //Response.Write("resultSize" + itemdetail2.resultSize + "
"); // Response.Write("pageIndex" + itemdetail2.pageIndex + "
"); } Response.Write("resultSize=" + itemdetail.resultSize + "

"); Response.Write("pageIndex=" + itemdetail.pageIndex + "

"); } 

‘sb’是实际的字符串，即在此回复之上首先提到的JSON数据字符串

这基本上是 – web应用程序asp.net c＃代码….

N快乐……
