public void Open(

Parameters

stream

System.IO.Stream that contains a zip file.

This method allows you to open and work with a zip file stored in a stream instead of in an actual file.

Typical usage scenarios for this are zip files stored as application resources or in binary database fields.

The example below loads information from a zip file stored in an embedded resource. To embed a zip file in an application, follow these steps:

1) Right-click the project node in Visual Studio, select the Add | Add Existing Item... menu option.

2) Select a zip file to add to the project as an embedded resource.

3) Select the newly added file and make sure the Build Action property is set to "Embedded Resource".

// get Stream from application resources
System.Reflection.Assembly a = this.GetType().Assembly;
using (Stream stream = a.GetManifestResourceStream("MyApp.test.zip"))
{
  // open C1ZipFile on the stream
  zip.Open(stream);
            
  // enumerate the entries in the zip file,
  foreach (C1ZipEntry ze in zip.Entries)
  {
    // show entries that have a 'txt' extension.
    if (ze.FileName.ToLower().EndsWith(".txt"))
    {
      using (var sr = new StreamReader(ze.OpenReader()))
      {
        MessageBox.Show(sr.ReadToEnd(), ze.FileName);
      }
    }
  }
}
