動的JSONをHTMLテーブルに変換する方法

Question

JSONをHTMLテーブルとして表示し、できるだけ簡単にフォーマットする必要があるという要件があります。

PartialViewを使用してテーブルを再帰的にレンダリングし、ほとんどの詳細を表示するにはどうすればよいでしょうか？

Answer 1

これを行う最も良い方法は、Newtonsoft.Jsonを使用してデータを動的に解析し、簡単にフォーマットできることでした。

メインビュー：

@{ 
    var converted = JsonConvert.DeserializeObject(Model.JsonData); 
    if (converted is JObject) 
    { 
     isMultiLevel = true; 
    } 
    else if (converted is JArray) 
    { 
     isSingleLevel = true; 
    } 
} 

@if (isMultiLevel) 
{ 
    Html.RenderPartial("Details_MultiLevelResult", Model); 
} 
else if (isSingleLevel) //might not be multiLevel nor singleLevel (if no data) 
{ 
    Html.RenderPartial("Details_SingleLevelResult", Model); 
}

    JObject json = JsonConvert.DeserializeObject(Model.JsonData) as JObject;

Answer 2

public class MyClass 
    { 
     public string name { get; set; } 
    } 

    var converted = JsonConvert.DeserializeObject<MyClass>(Json);
