Simple class with 3 properties. I send object of this class. How can I i loop get all property names and its values e.g. to one dictionary?

foreach (PropertyInfo pi in t.GetProperties())
    {
        myDict[pi.Name] = pi.GetValue(data,null)?.ToString();

    }

@AdrianIftode, It looks like we all got one (including the OP). I've up-voted you to compensate. – James Hill Apr 25 '12 at 14:23
can be data be an extension? – Demodave Jun 30 '17 at 21:11
@Demodave, Probably yes, depends what you want. Do you want to create a dictionary from the properties of an object of `myClass` type? – Adrian Iftode Jul 01 '17 at 00:04

If you have a null value it'll throw an exception when you call ToString(), so you should change it to pi.GetValue(data,null) != null ? pi.GetValue(data,null).ToString() : ""; – David Klempfner Dec 14 '18 at 06:40

This should do what you need:

MyClass myClass = new MyClass();
Type myClassType = myClass.GetType();
PropertyInfo[] properties = myClassType.GetProperties();

foreach (PropertyInfo property in properties)
{
    Console.WriteLine("Name: " + property.Name + ", Value: " + property.GetValue(myClass, null));
}

Output:

Name: a, Value: 0

Name: b, Value: 0

Name: c, Value: 0
