c# - How to unzip files from all the folders using SharpZipL

Question

I have installed SharpZip lib and want to unzip a zip folder in "@C:\Users\username\Desktop\Convert". Inside the convert folder there will be many sub folders where one folder will have only one zip file (I know we can use SearchOption.AllDirectories to search all the directories for zip file, but i'm not sure on how to carry this out ). So i want to unzip that file and extract it to a certain location. The unzipped file will have a CSS file . I want to check the CSS file certain attributes (multiple) one example : "line-height:" property and throw a message to the user in cmd saying that this CSS has "line-height" property. Can someone help me with this? I'm new to the SharpZipL lib.
