How to decode special character in Request.QueryString?

I am passing '© Alt+ 0169' in my serach fields in query string.

When i am getting QueryString in page like Request.QueryString("Sear开发者_如何学GochVal") then value will be : '© Alt 0169' .

It reomove '+'.

Could u tell me how can i get it..

Use System.Web.HttpUtility.UrlEncode() method.

string encode = HttpUtility.UrlEncode("© Alt+ 0169");
Response.Redirect("Page1.aspx?searchVal=" + encode);
