I have a dictionary variable in C# (ASP.NET). I want to send this data

  • 0

I have a dictionary variable in C# (ASP.NET). I want to send this data to Javascript. I am using this code to serialize it and send to javascript.

Dictionary<string, string> chat;
chat = new Dictionary<string, string>();

chat.Add("Sam", "How are you?");
chat.Add("Rita", "I am good");
var serialize = new System.Web.Script.Serialization.JavaScriptSerializer();

Response.Write(serialize.Serialize(chat));

On the Javascript page, I am calling this page using this;

 $.ajax({
 url: "TextChatCalls/getChat.aspx",
 type: "POST",
 context: document.body,
 success: function (response) {
          var Chats = response.split('\n')[0];
          alert(Chats);

          }
 });

The value in Chats var is {"Sam":"How are you?","Rita":"I am good"}

I don’t know how do I read this value in Chats. Can I anyhow convert this into a 2D array and read it as array[0][0], array[1][0] etc. ?

Thanks.

EDIT:
One more confusion is that, the response object, returned from ASP.NET, contains

{"Sam":"How are you?","Rita":"I am good"}

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head><title>

</title></head>
<body>
    <form name="form1" method="post" action="getChat.aspx?Id=141755" id="form1">
<div>
<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="/wEPDwULLTE2MTY2ODcyMjlkZJctiKZK4rXVndR3mbGssIarCrOF" />
</div>

    <div>

    </div>
    </form>
</body>
</html>

And not just {"Sam":"How are you?","Rita":"I am good"} as expected. And hence I have to split the response object by var Chats = response.split('\n')[0]; which makes it an string!

    You read like this:

    alert(Chats["Sam"]);

    (so like a C# Dictionary :-). You read/write to it using something like Chats["propertyName"])

    or, to go through each value:

    for (var c in Chats)
{
    if (Chats.hasOwnProperty(c)) 
    {
        alert(c + '   ' + Chats[c]);
    }
}

    Note that this is different than C#. In C# c would contain a KeyValuePair<> containing both the key and the value. In Javascript c is only the key and to get the value you have to use Chats[c].

    (the reasoning for hasOwnProperty is here http://yuiblog.com/blog/2006/09/26/for-in-intrigue/)

    Now… If you really want to split it:

    var array = [];

for (var c in Chats)
{
    if (Chats.hasOwnProperty(c)) 
    {
        array.push([c, Chats[c]]);
    }
}
