combine C# and javascript code

i have a javascript alert in C# code like this

if(Session["msg"] != null){
       string msg = (string)Session["msg"];
       if(msg.Length > 2) {
           @: var msg = @msg;
           @: alert(msg);
                               }

But in the view the alert doesn't appear:

result

The problem is that the alert message is written to the view.

Why does this happen? How can I fix this?

You need to wrap the injected Razor string in quotes:

@: var msg = "@msg";

Let's say the content of "msg" is "Something" ... then, without the quotes, the rendered script would look like this:

var msg = Something

Which would be invalid, because there's no variable named "Something".
