❔ Get Array From Cookies using C#

Hi Everyone, So I got a problem with getting the Cart array from cookies, I use this code

Request.Cookies.TryGetValue($"Cart{user.Id}", out var cart);

Request.Cookies.TryGetValue($"Cart{user.Id}", out var cart);

Request.Cookies.TryGetValue($"Cart{user.Id}", out var cart);

Request.Cookies.TryGetValue($"Cart{user.Id}", out var cart);

to get the array out of cookie but it returns me this "[8" and what I got stored in the Cookies its

Cart1=[8,2002,6,4]

Cart1=[8,2002,6,4]

Cart1=[8,2002,6,4]

Cart1=[8,2002,6,4]

I'm assuming when you say it returns you "[8", that value is from the debugger?

Cookies are separated with commas. Cookies are basically stored as

foo=bar,baz=34323,token=b84tbysdf8tv3,theme=dark

foo=bar,baz=34323,token=b84tbysdf8tv3,theme=dark

So cookies like

foo=bar,baz=[234,543,676],theme=light

foo=bar,baz=[234,543,676],theme=light

will be treated as

foo = bar
baz = [234
543 = 
676] = 
theme = light

foo = bar
baz = [234
543 = 
676] = 
theme = light

HttpClientHttpClient suffers a similar issue, apparently

Seems like it was fixed with .NET 7, but the issue isn't closed yet so ¯\_(ツ)_/¯

I'd maybe encode the cookie value, treat it as a string, then decode it server-side

Was this issue resolved? If so, run

/close

/close

otherwise I will mark this as stale and this post will be archived until there is new activity.
