I have a class:

class A {
    public string a = \"A-val\" , b = \"B-val\";
}

I want to print the object members by reflection

    Once fixed to get rid of the errors (lacking a semi-colon and a bad variable name), the code you've posted does work - I've just tried it and it showed the names and values with no problems.

    My guess is that in reality, you're trying to use fields which aren't public. This code:

    FieldInfo[] fields = data.GetType().GetFields();
    

    ... will only get public fields. You would normally need to specify that you also want non-public fields:

    FieldInfo[] fields = data.GetType().GetFields(BindingFlags.Public | 
                                                  BindingFlags.NonPublic | 
                                                  BindingFlags.Instance);
    

    (I hope you don't really have public fields, after all...)
