public void Main()
{
string folderDirectory = Dts.Variables["dirDestinationFolder"].Value.ToString();
string fileName = "Report " + Dts.Variables["varEndDate"].Value.ToString() + ".xls";
CompressReportsFolder(fileName, folderDirectory);
Dts.TaskResult = (int)ScriptResults.Success;
}

public void CompressReportsFolder(string fileName, string folderDirectory)
{
ZipFile zip = new ZipFile();

string strOriginFilewithPath = folderDirectory + fileName;
zip.AddFile(strOriginFilewithPath);


string strCompressedFilewithPath = folderDirectory + fileName.Replace(".xls", ".zip");
zip.Save(strCompressedFilewithPath);
}

Output: compress the file with the directory, but i need just the compressed file. Thanks
