How do I transfer simple parameter from one ASP.Net page to another?

Question

In the course I'm taking they taught me to use Response.Redirect like this:

Response.Redirect(string.Format("name.aspx?sb="+bts+"&del="+delimiter));

Is there a better way to do so?

Answer 1

Specifically what you are discussing is the means to transfer state between pages. That can be done in an handful of ways:

1. Query string parameters. This is the equivalent of what you have done in your post.
2. Session. In this scenario, you would populate a Session variable on one page and then retrieve it on the other.
3. Cookies.
4. Form variables if you post directly to the page in question.

Answer 2

See How to: Pass Values Between ASP.NET Web Pages.

In addition you can also use the HttpContext.Current.Items collection to pass data if you are performing a Server.Transfer instead of a Response.Redirect.

Also, the code snippet:

• Is just performing string concatenation so you don't need to call string.Format.

• Should UrlEncode query string parameters

e.g.

Response.Redirect("name.aspx?sb=" + Server.UrlEncode(bts) 
    + "&del=" + Server.UrlEncode(delimiter));
