C# Printing Properties

I have a class like this with a bunch of properties:

class ClassName
{
     string Name {get; set;}
     int Age {get; set;}
     DateTime BirthDate {get; set;}
}

I would like to print the name of the property and it's value using the value's ToString() method and the Property's name like this:

ClassName cn = new ClassName() {Name = "Mark", Age = 428, BirthData = DateTime.Now}
cn.MethodToPrint();

// Output
// Name = Mark, Age = 428, BirthDate = 12/30/2010 09:20:23 PM

Reflection is perfectly okay, in fact I think it is probably required. I'd also be neat if it could somehow work on any class through some sort of inheritance. I'm using 4.0 if that matters.

Like you mentioned, you can accomplish this with reflection. Make sure you're using System.Reflection.

public void Print()
{
    foreach (PropertyInfo prop in this.GetType().GetProperties(BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance))
    {
        object value = prop.GetValue(this, new object[] { });
        Console.WriteLine("{0} = {1}", prop.Name, value);
    }
}

If you are only going to use this class, you can override the ToString method, like this:

public override string ToString()
{
    return string.Format("Name = {1}, Age = {2}, BirthDate= {3}", Name, Age, BirthData.ToLongTimeString());
}

If you need to represent only that class, then this would be the solution. You can do something like 

ClassName jhon = ....
Console.WriteLine(jhon);

What you want is typeof(ClassName).GetProperties(). This will give you an array of PropertyInfo objects, each of which has a Name property as well as a GetValue method.
