In most of the websites we have contact forms and other forms where we have some standard inputs like Phone,Email and Website URL and those are widely used in any site and has specific features. Email is one of the most standard used input elements which are used in our forms.

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.

So let’s take a simple example to see how we can pass parameters to the page methods. I am going to create a page method Hello World which takes name as parameter and return a string to greet user from that page method below is code for that.

using System; using System.Web.Services; namespace PageMethods { public partial class Test : System.Web.UI.Page { [WebMethod] public static string HelloWorld(string name) { return string.Format("Hi {0}",name); } } }
