Problem on zip and unzip files using C#(Asp.Net)

 Hi:
     I have met some Error on while zip,unzip files using c#.The error is

Error: "The non-generic type 'java.util.List' cannot be used with type arguments . " 

I have met this error on the following method.

 

 

  private List GetZipFiles(ZipFile zipfil)
    {

        List lstZip = new List();

        Enumeration zipEnum = zipfil.entries();
       
        while (zipEnum.hasMoreElements())
        {
            ZipEntry zip = (ZipEntry)zipEnum.nextElement();

            lstZip.Add(zip);
        }
       
        return lstZip;

    }

I have mentioned the  Entire code below, can any one solve this issue.

My Code:

 

 

using java.util;

using java.util.zip;

using java.io;

 

private void Zip(string zipFileName, string[] sourceFile)

{

    FileOutputStream filOpStrm = new FileOutputStream(zipFileName);

    ZipOutputStream zipOpStrm = new ZipOutputStream(filOpStrm);

    FileInputStream filIpStrm = null;

    foreach(string strFilName in sourceFile)

    {

         filIpStrm = new FileInputStream(strFilName);

         ZipEntry ze = new ZipEntry(Path.GetFileName(strFilName));

         zipOpStrm.putNextEntry(ze);

         sbyte[] buffer = new sbyte[1024];

         int len = 0;

       while( (len=filIpStrm.read(buffer)) >= 0) 
        { 
            zipOpStrm.write(buffer, 0, len); 
        }

     }

     zipOpStrm.closeEntry();

     filIpStrm.close();

     zipOpStrm.close();

     filOpStrm.close();

}

 

    private void Extract(string zipFileName, string destinationPath)

{

    ZipFile zipfile = new ZipFile(zipFileName);

    List zipFiles = GetZipFiles(zipfile);

    foreach (ZipEntry zipFile in zipFiles)

    {

        if (!zipFile.isDirectory())

        {

            InputStream s = zipfile.getInputStream(zipFile);

            try

            {

                Directory.CreateDirectory(destinationPath + "\\" + Path.GetDirectoryName(zipFile.getName()));

                FileOutputStream dest = new FileOutputStream(Path.Combine(destinationPath + "\\" + Path.GetDirectoryName(zipFile.getName()), Path.GetFileName(zipFile.getName())));

                try

                {

                    int len = 0;

                    sbyte[] buffer = new sbyte[7168];

                    while ((len = s.read(buffer))>= 0)

                    {

                        dest.write(buffer, 0, len);

                    }

                }

                finally

                {

                    dest.close();

                }

            }

            finally

            {

                s.close();

            }

        }

     }
    }

    private List GetZipFiles(ZipFile zipfil)
    {

        List lstZip = new List();

        Enumeration zipEnum = zipfil.entries();
       
        while (zipEnum.hasMoreElements())
        {
            ZipEntry zip = (ZipEntry)zipEnum.nextElement();

            lstZip.Add(zip);
        }
       
        return lstZip;

    }

}
