Decoding the url querystring

Question

Hi I am sending the query string as below ?query=%barbara&no=1 After the getting from the qury string i decoded it. While decoding the query string the %ba will converted into a null string How can i avoid it.

The % sign in this context is used to say the following 2 characters are the hex code for some character. For example %20 is the UrlEncoded format for a space. %BA is the UrlEncoded format for a character of hex code BA which is unprintable - hence you get nothing. If you need to actually have the % sign as itself use the hex code for the % sign - which is 25. So you would have: ?query=%25barbara&no=1 Is this what you were after?
