PHP webservice return mixed data how can i use it in c#

Question

i have web service in php which contain method (login) that should return false or associated array !

iam trying to use it in c# , but c# keep telling me that i must use object to handle returned data and so i did , but i cant parse anything of data

this is a glimpse of code

        object user;
        user = Chat.login(txtUsername.Text,txtPassword.Text);

        if (user.Equals(false))
        {
            MessageBox.Show("Error !");
        }
        else {
           //i wanna here for example show user['name'] for example
        }

the above code works fine if user entered wrong data , and if it's in system it return mixed data (array of user data) but i can't use it

What sort of data in what format does the PHP service return? JSON? Please show the raw output that you are trying to parse. — DaveRandom

Fire up a debugger and hover over the user when the login was successful. What type is it of? — Nikola Anusev

It sounds like you've implemented the php webservice yourself, in which case you should return a fixed type or null, rather than false. (I think c# will handle/understand null). — Bob Davies

You should rewrite the webservice so that it returns an object instead of two different types. In JSON it should look like,

{"status": "SUCCEDED", "result": [1,2,3,4]} // valid login
{"status": "FAILED"} // valid login

Then you can check if status is "SUCCEDED".

Another approach is to return an array. On success return associative array. On failure return an empty array. This allows you to check the length of the array to determine the success.

[1,2,3,4] // valid login
[] // valid login

The example is in JSON. You can convert it to XML anyway. Most important thing is that you should have got the idea.

@SamyMassoud You can use JSON.NET to parse JSON. See (the only answer to this question)[stackoverflow.com/questions/9963079/…
