GoogleUser  user = new JavaScriptSerializer().Deserialize<GoogleUser>(json);

I am developing in C# 4.0 I use login with google+ button in my project. I would like to get user's by using access_token. I can get them as json filen. Then I would like to copy them my GoogleUser class. I don't get error, But user always equal null. By this way, yesterday I could get user's data, but not today.

What can be my problem ?

<code>string a</code> is not <code>null</code>, it is my <code>json</code> file, but <code>user</code> is <code>null</code>

First thing; browser is probably caching the request / data and screwing things up (chrome is good at screwing up javascript caching) and secondly; I would use the JsonProperty attribute for multiple reasons, e.g. [JsonProperty("kind")] and then Propercase the property. — BLoB

I will try JsonProperty, but it worked yesterday by this way. — Jeyhun

Indeed, that won't fix it, but I think it s a good practice... try completely clearing your browser cache... which browser are you using by the way? — BLoB

Can you try:

user =  new JavaScriptSerializer().Deserialize<A>( a );

since you say "a" has the value in the string. Maybe the problem is that you are calling ReadToEnd twice?

I added picture after posted my question, therefore other users couldn't see it, Thank you very much, now it works. I added string a today )

For example I have name ="Jeyhun" surname="Elvin" in json file. I would like to get only name. Am I obliged to declare in my USERS class surname too? or it is enough USERS class { public string name {get; set;} }

I'd say try it out. I'm not sure. I would think it would work.
