UnSupported Compression method


I was writing a piece of code which generates zip file from the files read from Database and send  as an attachment mail to user. I used SharpZiLib library for that. And i completed writing my logic and mail goes fine to user’s mail box. So, far so good :). But when user tries to extract the attached zip file using 7Zip it shown following error and was working fine with winzip:
UnSupported Compression method for FILENAME.FILEXTENSION ERROR


Then i just started going through the code and i just commented following line of cod and it worked!
[sourcecode language=”csharp”]
//Crc32 crc = new Crc32();
//zipEntry.Crc = crc.Value;
Hope this helps you to resolve your problem and say happy zipping!
