Advantages of JSON
- Smaller message size
- Information are stored in more structural document.
- It can easily distinguish the number and string i.e. 1 and “1”
- Easy to represent NULL value.
By using newtonsoft json(Which is available in Nuget Package Manager) we can easily convert the list object to the string which contain corresponding Json.
Below I have provided methods to Convert List Object to JSON ASP.NET String in Technology.
JSON Serialization Method:
Below method is use to convert object list to Json formate string.
List _EmployeeDetails= new List();
EmployeeDetails user = new EmployeeDetails();
EmployeeDetails.Add(new EmployeeDetails{ EmployeeID= 1, UserName= "Rajesh", Location= "Chennai" });
string strserialize = JsonConvert.SerializeObject(EmployeeDetails);
JSON DeSerialization Method
Following is the serialize method to serialize list items into JSON string format. Again this is achieved by Newtonsoft.
C# Source Code
string strmsg = "[{\"EmployeeID\":1,\"UserName\":\"Rajesh\",\"Location\":\"chennai\"},{\"EmployeeID\":2,\"UserName\":\"Mahesh\",\"Location\":\"Surat\"}]";
var user = JsonConvert.DeserializeObject<List>(strmsg);
Below I have demonstrate complete working example for serialization and deserialization for Json Data.
create new web application and open your Default.aspx page and write the code like as shown below.
<form id="frmMain">
<div>
<div>
Serialized Data:
</div>
<div>
DeSerialized Data:
</div>
</div>
</form>
Now write below code in code behind file of above .aspx file.
using Newtonsoft.Json;
using System;
using System.Collections.Generic;
namespace Json
{
public partial class Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnSerialize_Click(object sender, EventArgs e)
{
List details = new List();
EmployeeDetails user = new EmployeeDetails();
details.Add(new EmployeeDetails { EmployeeID = 1, UserName = "Rajesh", Location = "Chennai" });
details.Add(new EmployeeDetails { EmployeeID = 1, UserName = "Mahesh", Location = "Surat" });
details.Add(new EmployeeDetails { EmployeeID = 1, UserName = "Naresh", Location = "Delhi" });
string strserialize = JsonConvert.SerializeObject(details);
lblserial.Text = strserialize;
}
protected void btnDeserialize_Click(object sender, EventArgs e)
{
string strmsg = "[{\"EmployeeID\":1,\"UserName\":\"Rajesh\",\"Location\":\"chennai\"},{\"EmployeeID\":2,\"UserName\":\"Mahesh\",\"Location\":\"Surat\"}]";
var user = JsonConvert.DeserializeObject<List>(strmsg);
}
}
class EmployeeDetails
{
public int EmployeeID { get; set; }
public string UserName { get; set; }
public string Location { get; set; }
}
}
This is how we can convert object list to Json String.
