Question

I have one class that inherits another. I want to use reflection to cycle through the properties and write the values to a file. No problem. Except that I want to control the order in which the properties write out. Is there a clean way to do this? Right now, problem 1 is that the properties in the the subclass write out and THEN the proepries in the parent class write out. But also, I may want to skip some properties or just reorder them.

Here is my code now…

foreach (PropertyInfo bp in t.GetProperties())
{
    Type pt = bp.PropertyType;

    if ((pt.IsArray) && pt.FullName == "System.Char[]")
    {
        char[] caPropertyValue;
        caPropertyValue = (char[])(bp.GetValue(oBatch, null));
        string strPropertyValue = new string(caPropertyValue);
        myBatch.Add(strPropertyValue);
    }
}

Answer 1

You could create your own Attribute i.e. ”’OrderAttribute”’ and place it over property
such as

public class Man
{
   [Order(0)]
   string Name {get; set;}
   [Order(1)]
   int virtual Age {get; set;}
}
public class SuperMan:Man
{
   [Order(-1)]
   override int Age {get; set;}
}

in the sorting routine you can check order attribute value via pi.GetCustomAttribute() and sort pi’s over it.
