hi ankit,

You can use GZipStream class.

string fileToBeCompressed =//path of original file;
string zipFilename = //path of zipped file;
 
using (FileStream target = new FileStream(zipFilename, FileMode.Create,FileAccess.Write))
using (GZipStream alg = new GZipStream(target, CompressionMode.Compress))
{
    byte[] data = File.ReadAllBytes(fileToBeCompressed);
    alg.Write(data, 0, data.Length);
    alg.Flush();
}
