Problem while opening a zip file

Question

I have a problem when opening a zip file. I am using this code to zip the file:

public static string Zip_File(string soruce , string target)
        {
            try
            {
                byte[] bufferWrite;               
                using (FileStream fsSource = new FileStream(soruce, FileMode.Open, FileAccess.Read, FileShare.Read))
                {
                    bufferWrite = new byte[fsSource.Length];
                    fsSource.Read(bufferWrite, 0, bufferWrite.Length);
                    using (FileStream fsDest = new FileStream(target, FileMode.OpenOrCreate, FileAccess.Write))
                    {
                        using (GZipStream gzCompressed = new GZipStream(fsDest, CompressionMode.Compress, true))
                        {
                            gzCompressed.Write(bufferWrite, 0, bufferWrite.Length);
                            bufferWrite = null;
                            fsSource.Close();
                            gzCompressed.Close();
                            fsDest.Close();
                        }
                    }
                }
                return "success";
            }
            catch (Exception ex)
            {
                return ex.Message;
            }
        }

When I call this function am receiving "success" message, but I can't able to open the zip file.

ZipFiles.Zip_File(@"C:\Documents and Settings\ccspl\Desktop\IntegrityDVR.mdb", @"C:\Documents and Settings\ccspl\Desktop\a.zip")

This is my function call code:

the compressed(folder) is invalid or corrupted ...> this is error message which I have received

Answer 1

GZipStream does not create .zip files. It creates .gz files. If you need to create .zip files, you should use something like SharpZipLib.

Answer 2

but, wait a minute, GZipStream doesn't create zip file, it creates gzip files as I know, Zipping files using GZipStream should help

Answer 3

Why not use SharpZipLib? It makes this a lot easier.

Answer 4

sample code for DotNetZip, an open source zip library.

public static string ZipFile(String source, String target)
{
    try 
    {
        using (ZipFile zip = new ZipFile()
        {
            zip.AddFile(source);
            zip.Save(target);
        }
        return "success";
    }
    catch {}
    return "failure";
}
