Read from html 5 local storage with selenium

Question

I am using selenium web driver in c#. when i write to local storage with JavaScript method it works fine ( i can see the values in the html page with inspect ), but if i try to read from local storage what i just wrote it returns Null. Thanks for any help .

Writing (works):

IJavaScriptExecutor js = (IJavaScriptExecutor)driver;      
js.ExecuteScript("localStorage.setItem('key','value');");  

Reading (returns Null ):

Object Value= js.ExecuteScript("localStorage.getItem('key')");

Answer 1

First of all, you should return the value, secondly you should cast the return value to a known type.

value = (String) js.executeScript("return localStorage.getItem('key')");

Answer 2

Update to the question, in 2018 with c# you would do:

browser.WebStorage.LocalStorage.GetItem("item")
