Answer 1

Hi,

I will provide you two solutions.

1) First you need to refer free dll "Ionic.Zip" from Microsoft in your project.

download location : http://dotnetzip.codeplex.com/releases/view/27890 

Download "DotNetZipLib-Runtime-v1.9.zip", then refer "Ionic.Zip" dll from DotNetZip-v1.9 folder.

Code snippet for unzip folder is as below:

 

/// <summary>
    /// This method is used to extract zip file.
    /// </summary>
    /// <param name="src">Source zip file path.</param>
    /// <param name="target">Target extract location.</param>
    private void ExtractZip(string src, string target)
    {
      try
      {
        ZipFile zip = new ZipFile(src); zip.Password = "";
        zip.ExtractAll(target, ExtractExistingFileAction.OverwriteSilently);
        zip.Dispose();
        zip = null;
      }
      catch (Exception ex)
      {
        Trace.WriteLine("Extract fail for file : " + src);
        Trace.WriteLine(ex);
      }
    }

hi i used your code after downloading that file but it is not showing any result my code is below

 

 

try

{

 

String src=@"D:\ASI\Flood\Download";

 

String target = @"D:\ASI\Flood\Production";

Ionic.Zip.

ZipFile zip = new Ionic.Zip.ZipFile(src); zip.Password = "";

zip.ExtractAll(target,

ExtractExistingFileAction.OverwriteSilently);

zip.Dispose();

zip =

null;

}

 

catch (Exception ex)

{

 

//Trace.WriteLine("Extract fail for file : " + src);

 

//Trace.WriteLine(ex);

 

MessageBox.Show(""+ex.Message);

}

Hi,

As i have mentioned earlier that, in the String src  variable you need to give source zip file path.

You have'nt  added zip file path.

Your path must be like String src=@"D:\ASI\Flood\Download\sampleFile.zip";
