在C＃中的JSON（最好沒有第三方工具）

Question

我見過很多方法在C＃中輸出JSON。然而，他們中的任何一個都不容易。這可能是由於我缺乏C＃知識所致。

問題：如果您要編寫JSON（稍後在JavaScript中使用），您將如何執行此操作？我寧願不使用第三方工具;然而，這不是任何形式的最後通。。 JSON可以在C＃ASP.NET中使用嗎？ JSON的

例子我希望寫：

{ 
    "Trips": [ 
     { 
      "from": "here", 
      "to": "there", 
      "stops": [ 
       { 
        "place": "middle1", 
        "KMs": 37 
       }, 
       { 
        "place": "middle2", 
        "KMs": 54 
       } 
      ] 
     }, 
     { 
      "from": "there", 
      "to": "here", 
      "stops": [ 
       { 
        "place": "middle2", 
        "KMs": 37 
       }, 
       { 
        "place": "middle1", 
        "KMs": 54 
       } 
      ] 
     } 
    ] 
}

怎麼樣JavaScriptSerializer？好的集成解決方案，允許用JavaScriptConverter s擴展。

演示的你是什麼後：

using System; 
using System.Web.Script.Serialization; 
using System.Text; 

public class Stop 
{ 
    public String place { get; set; } 
    public Int32 KMs { get; set; } 
} 

public class Trip 
{ 
    public String from { get; set; } 
    public String to { get; set; } 
    public Stop[] stops { get; set; } 
} 

public class MyJSONObject 
{ 
    public Trip[] Trips { get; set; } 

    public override String ToString() 
    { 
     StringBuilder sb = new StringBuilder(); 
     foreach (Trip trip in this.Trips) 
     { 
      sb.AppendFormat("Trip:\r\n"); 
      sb.AppendFormat("\t To: {0}\r\n", trip.to); 
      sb.AppendFormat("\t From: {0}\r\n", trip.from); 
      sb.AppendFormat("\tStops:\r\n"); 
      foreach (Stop stop in trip.stops) 
      { 
       sb.AppendFormat("\t\tPlace: {0}\r\n", stop.place); 
       sb.AppendFormat("\t\t KMs: {0}\r\n", stop.KMs); 
      } 
      sb.AppendLine(); 
     } 
     return sb.ToString(); 
    } 
} 
public class Test 
{ 
    public static void Main() 
    { 
     String example = "{\"Trips\":[{\"from\":\"here\",\"to\":\"there\",\"stops\":[{\"place\":\"middle1\",\"KMs\":37},{\"place\":\"middle2\",\"KMs\":54}]},{\"from\":\"there\",\"to\":\"here\",\"stops\":[{\"place\":\"middle2\",\"KMs\":37},{\"place\":\"middle1\",\"KMs\":54}]}]}"; 

     JavaScriptSerializer serializer = new JavaScriptSerializer(); 

     // Parse the string to our custom object 
     MyJSONObject result = serializer.Deserialize<MyJSONObject>(example); 
     Console.WriteLine("Object deserialized:\r\n\r\n{0}\r\n\r\n", result); 

     // take our custom object and dump it in to a string 
     StringBuilder sb = new StringBuilder(); 
     serializer.Serialize(result, sb); 
     Console.WriteLine("Object re-serialized:\r\n\r\n{0}\r\n\r\n", sb); 

     // check step 
     Console.WriteLine(example.Equals(sb.ToString()) ? "MATCH" : "NO match"); 
    } 
} 

和輸出：

Object deserialized: 

Trip: 
      To: there 
     From: here 
     Stops: 
       Place: middle1 
        KMs: 37 
       Place: middle2 
        KMs: 54 

Trip: 
      To: here 
     From: there 
     Stops: 
       Place: middle2 
        KMs: 37 
       Place: middle1 
        KMs: 54 




Object re-serialized: 

{"Trips":[{"from":"here","to":"there","stops":[{"place":"middle1","KMs":37},{"pl 
ace":"middle2","KMs":54}]},{"from":"there","to":"here","stops":[{"place":"middle 
2","KMs":37},{"place":"middle1","KMs":54}]}]}

你真的應該看看Json.NET

這不僅寄望庫執行它可以解析JSON也是如此。這意味着你可以輕鬆地往返東西並通過JSON進行通信而不涉及WCF服務層。它還可以做其他精巧的事情，例如提供可查詢的動態對象模型。

有JavaScriptSerializer從System.Web.Extensions.dll（.NET 3.5 SP1）
