Extract .zip file From folder

Question

Hi,

 

I want extract .zip file from filder and rename inside zip file.

 

i am using below code for extract and its working also but how can i rename inside file.

if (ofd.ShowDialog() == DialogResult.OK)
{
Path_List.Items.Clear();
foreach (String file in ofd.FileNames)
{
if ((mystream = ofd.OpenFile()) != null) //have tried using Stream in different ways to no avail
{
using (mystream)
{
// populates text box with selected filenames ????? lists only 1 filename
Path_List.Items.Add(file);
txt_File_Count.Text = Path_List.Items.Count.ToString();
ZipFile zipFile = new ZipFile(file);
string fullPath = ofd.FileName;
string filename = ofd.SafeFileName;
string path = fullPath.Replace(filename, "");
zipFile.ExtractAll(path, ExtractExistingFileAction.DoNotOverwrite);
zipFile.ExtractAll(Application.StartupPath);
}
}
}
Path_List.Items.Clear();
