C# Systems.Reflection on IonicZip.dll

I have been using Reflection to use Ionic.Zip.dll. I am able to create an instance of the ZipFile type but not able to access the Read method to extract a file.

Kindly share your thoughts. Thanks

  var DLL = Assembly.LoadFile(@"C:\Tools Use\Ionic.Zip.dll");
        var ZipFile = DLL.GetType("Ionic.Zip.ZipFile");
        var c = Activator.CreateInstance(ZipFile);
        var method = ZipFile.GetMethod("Read", BindingFlags.Static);
        //var method = theType.GetMethod("Read");
        //method.Invoke(c, new object[] { @"C:\Source\Filea" });
