How do I use Encoding, Decoding in asp.net?

[chelvis]

I have a url something like this (this is a fake url):

http://www.mypage.aspx?aspx=B&K FunctionlGrp

I wrote a code to get the CID and then display that CID in another page as it is. Since the CID has the '&' sign, whatever comes after the & sign is not displaying. How should I handle this with encoding, decoding in asp.net?

Here is my partial code:

string sCID = Request.QueryString["CID"];

if (Request.QueryString["CID"] != null)
{
lnkHName = sCID;
}
else
{
//do something
}

I am displaying this lnkHName in a td tag and anything after & sign is lost. I looked at the www.w3schools.com website and they just give you all the encoding characters but dont explain how to do this in either VB.net or C#. Please help me. I use C# but vb also will help.

Hi Guys,
I found the answer for it. You have to use HttpUtility.UrlEncode before endcoding it and then you can use HttpUtility.UrlDecode to decode the characters.
