Deserialize POST data in JSON format in C#

Question

I need to capture/deserialize in C#, using only built-in .NET library, the JSON formatted POST data received from a JavaScript file.

The JSON format is:

{"URLs":[{"url_name":"Google", "url_address":"http://www.google.com/"}, {"url_name":"Yahoo", "url_address":"http://www.yahoo.com/"},{"url_name":"FB", "url_address":"http://www.fb.com/"},{"url_name":"MegaSearches", "url_address":"http://www.megasearches.com/"}]}

The JavaScript file POSTs the JSON data in http://www.mysite.com/json.aspx and I need to capture the JSON data in .aspx code-behind in C# and save to database.

Answer 1

First, create classes to hold the URL data, like this:

public class UrlData
{
    public List<Url> URLs {get;set;}
}

public class Url
{
    public string url_address {get;set;}
    public string url_name {get;set;}
}

Now you can deserialize the JSON data into the objects, like this:

UrlData theUrlData = new JavaScriptSerializer().Deserialize<UrlData>(jsonResult);

Note: jsonResult is the JSON data returned from where you are getting the data from.

Answer 2

Create a view model class for the incoming JSON data.

public class UrlHelper {
    public string url_name {get;set;}
    public string url_address {get;set;}
}

In the method in your code behind have the post method accept the data.

public YourJsonFormPost(List<UrlHelper> URLs){
    //do your work 
}
