Method 1:

Create two classes with the structure of your JSON string:

<pre><code>public class myobj
{
 public string dept;
 public IEnumerable&lt;mydata&gt;;
}

public class mydata
{
 public int weight;
 public int height;
}
</code></pre>

and after that use this to parse it:

<pre><code>public static T FromJSON&lt;T&gt;(string str)
{
 JavaScriptSerializer serializer = new JavaScriptSerializer();
 return serializer.Deserialize&lt;T&gt;(str);
}
</code></pre>

Like this:

<pre><code>myobj obj = MP3_SIOP_LT.Code.Helpers.JSONHelper.FromJSON&lt;myobj&gt;(@"{""dept"":""HR"",""data"":[{""height"":5.5,""weight"":55.5},{""height"":5.4,""weight"":59.5},{""height"":5.3,""weight"":67.7},{""height"":5.1,""weight"":45.5}]}");
</code></pre>

The result:

<a href="https://i.stack.imgur.com/Ygt1i.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/Ygt1i.png" alt="enter image description here"></a>

Method 2:

If you don't want to have classes with your JSON structure, use the same method as above like this but in order to get a <code>dynamic</code> object:

<pre><code>dynamic obj = MP3_SIOP_LT.Code.Helpers.JSONHelper.FromJSON&lt;dynamic&gt;(@"{""dept"":""HR"",""data"":[{""height"":5.5,""weight"":55.5},{""height"":5.4,""weight"":59.5},{""height"":5.3,""weight"":67.7},{""height"":5.1,""weight"":45.5}]}");
</code></pre>

The result:

blocks|key|704905|text|首先，为json创建一个模型。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|704906|public+class+Size
{
++++public+double+height+{+get;+set;+}
++++public+double+weight+{+get;+set;+}
}

public+class+MyData
{
++++public+string+dept+{+get;+set;+}
++++public+List<Size>+data+{+get;+set;+}
}|code-block|syntax|javascript|704907|现在您可以反序列化您的json。内置DataContractJsonSerializer|offset|length|style|CODE|704908|var+serializer+=+new+DataContractJsonSerializer(typeof(MyData));
var+data+=+(MyData)serializer.ReadObject(new+MemoryStream(Encoding.UTF8.GetBytes(json)));|704909|或使用Json.Net|704910|var+data+=+JsonConvert.DeserializeObject<MyData>(json);|704911|您甚至可以使用dynamic方式，而无需创建任何类。|704912|dynamic+dynObj+=+JsonConvert.DeserializeObject(json);

foreach(var+item+in+dynObj.data)
{

First create a model for your json

<pre><code>public class Size
{
 public double height { get; set; }
 public double weight { get; set; }
}

public class MyData
{
 public string dept { get; set; }
 public List&lt;Size&gt; data { get; set; }
}
</code></pre>

Now you can deserialize your json. With built-in <code>DataContractJsonSerializer</code>

<pre><code>var serializer = new DataContractJsonSerializer(typeof(MyData));
var data = (MyData)serializer.ReadObject(new MemoryStream(Encoding.UTF8.GetBytes(json)));
</code></pre>

or With <a href="http://www.newtonsoft.com/json" rel="nofollow">Json.Net</a>

<pre><code>var data = JsonConvert.DeserializeObject&lt;MyData&gt;(json);
</code></pre>

You can even go the <code>dynamic</code> way without creating any classes

<pre><code>dynamic dynObj = JsonConvert.DeserializeObject(json);

foreach(var item in dynObj.data)
{
 Console.WriteLine("{0} {1}", item.height, item.weight);
}
</code></pre>

blocks|key|702776|text|您可以使用NewtonSoft+Json.Net进行解析。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|702777|尝尝这个|702778|var+json+=+"{\"dept\":\"HR\",\"data\":[{\"height\":5.5,\"weight\":55.5},{\"height\":5.4,\"weight\":59.5},{\"height\":5.3,\"weight\":67.7},{\"height\":5.1,\"weight\":45.5}]}";

You can use <a href="http://www.newtonsoft.com/json" rel="nofollow">NewtonSoft Json.Net</a> for parsing.

Try this

<pre><code>var json = "{\"dept\":\"HR\",\"data\":[{\"height\":5.5,\"weight\":55.5},{\"height\":5.4,\"weight\":59.5},{\"height\":5.3,\"weight\":67.7},{\"height\":5.1,\"weight\":45.5}]}";
var foo = JsonConvert.DeserializeObject&lt;RootObject&gt;(json);

// Check Values
// var department = foo.dept;
// foreach (var item in foo.data)
// {
// var height = item.height;
// var weight = item.weight;
// }

public class Datum
{
 public double height { get; set; }
 public double weight { get; set; }
}

public class RootObject
{
 public string dept { get; set; }
 public List&lt;Datum&gt; data { get; set; }
}
</code></pre>

I want to parse JSON string in C# asp.net mVC3 but not getting idea of how to parse my json string.
my JSON String is like that:

<pre><code>{"dept":"HR","data":[{"height":5.5,"weight":55.5},{"height":5.4,"weight":59.5},{"height":5.3,"weight":67.7},{"height":5.1,"weight":45.5}]}
</code></pre>

Code:

<pre><code>var allData = { dept: deptname, data: arr};
var allDataJson = JSON.stringify(allData);
$.ajax({
 url: '&lt;%=Url.Action("funx","Controller")%&gt;',
 data: { DJson: allDataJson },
 async: false,
 cache: false,
 type: 'POST',
 success: function (data) {
 alert("success data: "+data);
 }

}); 

public String funx(string DJson)
{
 System.Diagnostics.Debug.WriteLine("Returned Json String:" + DJson);

 // var yourObject = new JavaScriptSerializer().Deserialize(DJson);
 return "successfull";
}
</code></pre>

I am new to asp.net. I want to parse the string and save it in database.
