I wanted to access a session variable in javascript in asp.net mvc application. I have found a way to do it in aspx view engine but not in razor.
Please tell me a way to access the session variables

You can do it this way for a String variable:
<script type="text/javascript">
var someSessionVariable = '@Session["SomeSessionVariable"]';
</script>
Or like this if it's numeric:
<script type="text/javascript">
var someSessionVariable = @Session["SomeSessionVariable"];
</script>
This is really not a very clean approach though, and requires inline JavaScript rather than using script files. Be careful not to get carried away with this.

I personally like the data attribute pattern.
In your Razor code:
<div id="myDiv" data-value="@Request.RequestContext.HttpContext.Session["someKey"]"></div>
In your javascript:
var value = $("#myDiv").data('value');

How can I access and get the value of this session from my Controller?

In any MVC or Web API controller, you can just type
var myValue = Session["MyKey"]; to get the value for "MyKey"For google searchers,
In addition, If you want to access the session variable in external .js file you can simply do like this,
------ SOME HTML PAGE ------
//Scripts below Html page
<script>
//Variable you want to access
var mySessionVariable = '@Session["mySessionVariable"]';
</script>
// Load External Javascript file
<script src="~/scripts/MyScripts/NewFile.js"></script>
Inside NewFile.js
$(document).ready(function () {
alert(mySessionVariable);
});

In my asp.net I am not getting the result by
<script type="text/javascript">
var someSessionVariable = '@Session["SomeSessionVariable"]';
</script>
But I get the answer by below code,
<script type="text/javascript">
var yourVariable = '<%= Session["SessionKey"] %>';
</script>

I think, you haven't used MVC in your application.
