string.format escape sequence in c#

Recently I was working on something and I need to put a curly bracket on the string with a string.format function but I was not aware how to to do it. So I did some search on internet and found how to give escape sequence in string.format. Suppose You need to put curly bracket then you have write two ‘{{‘ instead of { to put ‘{‘ and same way ‘}}’ to put ‘}’

Let’s take simple example. Following is a code where I am printing simple string with string.format and Response.Write.

using System;
using System.Web.UI;

namespace CallBack
{
    public partial class Index : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            Response.Write( string.Format(@"{{ escape sequence for string format from {0}}}", "DotNetJalps"));
        }

    }
}

Now let’s run that example in browser and let’s see how it goes.




That’s it. It’s very easy to use.Hope you liked it. Stay tuned for more..Happy Programming.

Following is a main differences between http handler and generic handler.

1. Generic handler has a handler which can be accessed by url with .ashx extension while http handler is required to be configured in web.config against extension in web.config.It does not have any extension
