Hello,

I have developed Web application in asp.net in which implemented zip folder and download functionality, I have refered below link :

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

and I have cutomized my button click event code as per requirement code is : 

            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 =  @"G:\Work_Backup2020\WebShreeGroup\ShreeGroupWeb\ShreeGroupWeb\ShreeGroupWeb\" + sdr.GetValue(0).ToString();
                             
                            zip.AddFile(filepath, "KMLFiles");
                        }
                    }
                }

and this code worked fine with this local path.

But as it's online web application, I have deployed it on server and edited this local path and given server URl to locate folder, after that my code is :

            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");
                        }
                    }
                }

after adding this online server path, it gives error as :

URI format not supported.

how to resolve this issue ?

Thanks
