Regarding URL Encoding in C#

Question

hello,
We have a need to compress a string into a representation that is shorter than the original string then to decompress it.  I wanted to know if there is a way to do this in .NET for strings that are about 1000-1500 characters (not extremely long, but
we need to compress them for use in a URL/querystring)(maximum length limit allowed is 256).
plz help me i am a beginner in programming.....plzzzzzzzzzzzzzz

I don't know what Magnus is on about with server urlencode.
That's.... not going to do you any good at all.
You could potentially zip a string and send that:
public static void CopyTo(Stream src, Stream dest) {
byte[] bytes = new byte[4096];
int cnt;
while ((cnt = src.Read(bytes, 0, bytes.Length)) != 0) {
dest.Write(bytes, 0, cnt);
public static byte[] Zip(string str) {
var bytes = Encoding.UTF8.GetBytes(str);
using (var msi = new MemoryStream(bytes))
using (var mso = new MemoryStream()) {
using (var gs = new GZipStream(mso, CompressionMode.Compress)) {
//msi.CopyTo(gs);
CopyTo(msi, gs);
return mso.ToArray();
public static string Unzip(byte[] bytes) {
using (var msi = new MemoryStream(bytes))
using (var mso = new MemoryStream()) {
using (var gs = new GZipStream(msi, CompressionMode.Decompress)) {
//gs.CopyTo(mso);
CopyTo(gs, mso);
return Encoding.UTF8.GetString(mso.ToArray());
static void Main(string[] args) {
byte[] r1 = Zip("StringStringStringStringStringStringStringStringStringStringStringStringStringString");
string r2 = Unzip(r1);

However
You might want to first consider using  a cookie instead if that is an option.
Note that either way you will need some actual code running on the client in order to do this.
Unless something very strange is going on then this would seem to not actually be an asp.net question.
Since it's calling something on a web server as opposed to the thing that is called on that web server I would think this forum could well be the correct one.
If this is to happen on a client from a web page then you will need javascript rather than c#.
