Hello

I have referred below article :

Zip a Folder (Directory) and Download in ASP.Net using C# and VB.Net

and customized code as per my requirements as below : (Button click event) 

It works fine on my local machine but as I have added URL path of remote server It gives error as :URI formats are not supported

How to resolve this problem

            try
            {
                using (ZipFile zip = new ZipFile())
                {
                    zip.AlternateEncodingUsage = ZipOption.AsNecessary;
                    zip.AddDirectoryByName("KMLFiles");
                    

                    con.Close();
                    SqlCommand cmd = new SqlCommand("select FilePath from FileMaster where FileType='KML'", con);
                    con.Open();
                    SqlDataReader sdr = cmd.ExecuteReader();
                    if (sdr.HasRows)
                    {

                        while (sdr.Read())
                        {
                            string filePath =  "http://revolutionit-004-site69.htempurl.com/" + sdr.GetValue(0).ToString();
                            
                            zip.AddFile(filepath, "KMLFiles");
                        }
                    }
                }
