The following code saves the zipped file in the server.
I have Ionic.Zip.dll in the bin folder
using System.IO;
using Ionic.Zip;
protected void btnzip_Click(object sender, EventArgs e)
    {
       
string path = Server.MapPath("~/App_Info_Folders/" + lblattfld.Text + "/");
        string[] filenames = Directory.GetFiles(path);

        using (ZipFile zip = new ZipFile())
        {
            zip.AddFiles(filenames, "files");
            zip.Save(Server.MapPath("~/samplefiles.zip"));

            lblmessage.Text = "ZIP File Created Successfully";

        }
      }
I want the code to be modified in such a way that the zipped file is directly saved on the client local computer through save file dialog box.

What is meaning of Directly save? If you want to save on client computer without informing user, it will not be possible, because of security issues in web application. Can be done with Windows Application only.

To VJsoft:
I mean save directly (without saving on server) on client computer of course with knowledge of user. Save file dialog box permits user to save on any location on the client user computer. I do not think the code is difficult at all. I am not able recall now.
To:
XGIS: client download samples are not helpful. I had seen them before approaching Experts-Exhange.

          WebClient req=new WebClient();
          HttpResponse response = HttpContext.Current.Response;
          response.Clear();

Apt and complete solution. The code is working to my expectations. Only a small correction is required
Intead of
string strURL=Server.MapPath("~/samplefiles.zip");
we need to use
string strURL = "~/samplefiles.zip";
