Creating a zip file from stream and downloading it. Below is the code.

FileStream stream=File.OpenRead(@"D:\FileDownLoad\DeskTop\1.txt");
MemoryStream MS=new MemoryStream();

ZipOutputStream zipOutputStream = new ZipOutputStream(MS);
zipOutputStream.SetLevel(9);
ZipEntry entry = new ZipEntry("1.txt");
zipOutputStream.PutNextEntry(entry);

byte[] buffer = new byte[stream.Length];
int byteRead = 0;

while ((byteRead = stream.Read(buffer, 0, buffer.Length)) > 0) 
    zipOutputStream.Write(buffer, 0, byteRead);

    zipOutputStream.IsStreamOwner = false;
    stream.Close();
    zipOutputStream.Close();
    MS.Position = 0;

    Response.ContentType = "application/application/octet-stream";
    Response.AppendHeader("content-disposition", "attachment; filename=\"Download.zip\"");
    Response.BinaryWrite(MS.ToArray());
