dim decoded as byte()
decoded=convert.frombase64string(strreturndata)  // strreturndata is base64 string
dim decoders as string
decoders = encoding.utf8.getstring(decoded)

now i want to decompress this string using gzip stream class in windows form

If you want to get back the Base64 string, use this.

Try this:

byte[] x = Convert.FromBase64String(decodedString);
string mytext = System.Encoding.utf8.getstring(x, 0, x.length)

If you need to do more compression, you can use Gzip compression and decompression or DeflateStream class.
