Any idea why? I’m assuming it is because running the SaveCookie method first saves the serialized CookieContainer object that has been initialized to redditCookie into the file before LoadCookie attempts to read data out of it. Simply creating an empty file and not calling SaveCookie first means that LoadCookie has nothing to read.

The second problem, and thus far the only other one, took place in the HasMail() function. In the if statement your code reads:

if ((string)me["has_mail"] == "true")

However, at least in .NET 4.0.30319, this results in the error “Cannot cast ‘me["has_mail"]‘ (which has an actual type of ‘bool’) to ‘string’ “. I changed the if statement to read:

if (Convert.ToString(me["has_mail"]) == "true")

That did the trick for my version of .NET.

Despite my two minor complaints (which would be even less minor for someone that wasn’t a C# novice), this API wrapper is fantastic. I actually plan on writing my own in the next week or so, just as practice. I will likely fall back on yours though, as your code is much better than mine. Anyway, I’d be interested to know if the problems I encountered aren’t applicable for you, for whatever reason.

thank you so much for implementing this. I just have a problem (stack trace attached below).

I used your .cs file and created new RedditAPI instance with my credentials. During the runtime the following exception is raised:

System.Runtime.Serialization.SerializationException was unhandled
Message=Attempting to deserialize an empty stream.

Any idea what might help?

Thank you in advance!
