Retrieving class attributes and their values

[ullner]

I have multiple classes, named A, B and C. I want to get the attributes of all classes and their values. How can I do this?

I can get the attribute names of (eg) the class "A" by;

Type classType = A.GetType();
PropertyInfo[] a_pi = classType.GetProperties();
foreach (PropertyInfo pi in a_pi)
     Console.WriteLine(pi.Name);

But I'm not able to get their values.

Hmm, there must be some way, because when you set an object as the datasource for a datatable, any public properties become columns and the values of those properties are inserted into them.

I think you would use:

classType.InvokeMember(pi.Name, BindingFlags.Default, null, myA, myArgs);

You will have to look up the arguments as I just kind of picked them at random.

Thanks. I used your solution (a bit modified);

            Type classType = A.GetType();
            PropertyInfo[] a_pi = classType.GetProperties();
            foreach (PropertyInfo pi in a_pi)
            {       
                Object obj = classType.InvokeMember(null,
                            BindingFlags.DeclaredOnly |
                            BindingFlags.Public | BindingFlags.NonPublic |
                            BindingFlags.Instance | BindingFlags.CreateInstance, null, null, null);
                
                object values =  classType.InvokeMember(pi.Name,
                            BindingFlags.DeclaredOnly |
                            BindingFlags.Public | BindingFlags.NonPublic |
                            BindingFlags.Instance | BindingFlags.GetProperty, null, obj, null);

                Console.WriteLine(values);

The problem is that if I use an instance of the type A, instead of directly A, I get the default values for that class, and not the modified values.
(That is, if I do

A a = new A();
a.someAttribute = someVal;
Type classType = a.getType();
...

)

Any suggestions?

So use the instance of A you want and don't create a new instance. I think that is stated somewhere in those bindingflags.
