使用C＃創建json格式

-1

嗨在下面的代碼中，我嘗試使用C＃動態創建json並將json對象作爲客戶端傳遞。我不能夠得到確切的JSON格式，根據下面的靜態JSON.Can你請幫我解決這個問題。我的目標是使用C＃獲取JSON格式。使用C＃創建json格式

精確JSON格式：

C＃：

object[,] arrData = new object[2, 3]; 


      arrData[0, 0] = "Product A"; 

      arrData[0, 1] = 567500; 

      arrData[0, 2] = 567500; 

      StringBuilder jsonData = new StringBuilder(); 

       StringBuilder categories = new StringBuilder(); 

      StringBuilder currentYear = new StringBuilder(); 

      StringBuilder lineset = new StringBuilder(); 


      jsonData.Append("{" + 

     //Initialize the chart object with the chart-level attributes.. 
       "'chart': {"+ 

        "'caption': 'Sales by Product'," + 
        "'numberPrefix': '$',"+ 
        "'formatNumberScale': '1'," + 
        "'placeValuesInside': '1'," + 
        "'decimals': '0'" + 
       "},"); 


      categories.Append("'categories': [" +

       } 
       categories.AppendFormat("{{" +

提供最小可重現的例子。 –

使用諸如https://www.nuget.org/packages/newtonsoft.json/的Json庫來創建它。比使用字符串操作更可靠。 – Chris

@JeroenHeier查看我的編輯 – Santhosh

使用我的回答here創建從JSON C＃類。然後創建一個類的實例，並用這樣的數據填充它：

var data = new WhateverYourClass(); 
// fill the properties

然後使用NewtonSoft NuGet包和這樣做是爲了把你的類實例成JSON（序列化）：

string json = JsonConvert.SerializeObject(data);
