            PackageInfos pInfos = app.GetDtsServerPackageInfos(@"File System", "YOURSERVER");
            Console.WriteLine("Number of Packages {0}", pInfos.Count.ToString());

            if (pInfos.Contains(0))
            {
                Console.WriteLine("Package {0} found ", pInfos[0].Name);
            }
            else
            {
                Console.WriteLine("Package cannot be found using Contains");
            }
         }
    }
}

            app.SaveToDtsServer(p1, Nothing, "File System\myp1Package", "YOURSERVER")
            app.SaveToDtsServer(p2, Nothing, "File System\myp2Package", "YOURSERVER")
 
            Dim pInfos As PackageInfos =  app.GetDtsServerPackageInfos("File System","YOURSERVER") 
            Console.WriteLine("Number of Packages {0}", pInfos.Count.ToString())
 
            If pInfos.Contains(0) Then
                Console.WriteLine("Package {0} found ", pInfos(0).Name)
            Else 
                Console.WriteLine("Package cannot be found using Contains")
            End If
