C # String.Format - invalid input string

Question

I have an MVC3 HtmlHelper extension, for example:

public static MvcHtmlString ShowInfoBar(this HtmlHelper helper, string message, InfoMessageType messageType) { return MvcHtmlString.Create(String.Format(@"<script type=""text/javascript"">$(document).ready(function () { gtg.core.showInfoBar('{0}', '{1}'}; );</script>", message, messageType.ToString().ToLower())); } 

The value of message is "The product "Product Name" was saved successfully."

messageType is info .

He keeps saying Input string was not in the correct format.

I am stuck??

Answer 1

On each curly brace that is not a token, you must double -

 function() {{ 

Etc

Also - consider XSS here - is this message properly escaped for insertion into JavaScript?

Answer 2

Reset your square brackets {{}} in the format string

 String.Format(@"<script type=""text/javascript"">$(document).ready(function () {{ gtg.core.showInfoBar('{0}', '{1}'); }});</script>", message, messageType.ToString().ToLower()) 

Answer 3

You need to avoid braces:

{{ and }}

 String.Format(@"<script type=""text/javascript"">$(document).ready(function () {{ gtg.core.showInfoBar('{0}', '{1}'}}; );</script>", message, messageType.ToString().ToLower())

In my case, I used a bracket to format JsonP. JsonP also requires "{". Breaking out of {like this: '{{', my problem was resolved.
