问题描述
I want to serialize multiple DataTables to JSON which are interrelated and it is possible there will be additional table are all set in the mapping table. In this case, I have 4 DataTables.
This is my first time using JSON, and I have found it really tricky to find a simple way of doing this. I have been using a StringBuilder at the moment to create a JSON string from the information in the dataset, but I have heard that it is possible to do this very simply with .NET 3.5 using the System.Runtime.Serialization namespace, though I have yet to find a simple article or blog on how this is done! What is the easiest way to do this?
我的尝试:
What I have tried:
I want JSON in below format.
{quiz": {
"Id": 2,
"name": "C# and .Net Framework",
"description": "C# and .Net Quiz (contains C#, .Net Framework, Linq, etc.)"
},
"config":{
"shuffleQuestions": true,
"showPager": false,
"allowBack": true,
"autoMove": true
},

推荐答案
你试过json.net吗?它允许你这样做:
Have you tried json.net? It lets you do this:
string json = JsonConvert.SerializeObject(dataSet, Formatting.Indented);
说真的,谷歌是你的朋友。
Seriously, google is your friend.
