How do I loop through a PropertyCollection

Can anyone provide an example of how to loop through a System.DirectoryServices.PropertyCollection and output the property name and value?

I am using C#.

@JaredPar - The PropertyCollection does not have a Name/Value property. It does have a PropertyNames and Values, type System.Collection.ICollection. I do not know the basline object type that makes up the PropertyCollection object.

@JaredPar again - I originally mislabeled the question with the wrong type. That was my bad.

Update: Based on Zhaph - Ben Duguid input, I was able to develop the following code.

using System.Collections;
using System.DirectoryServices;

public void DisplayValue(DirectoryEntry de)
{
    if(de.Children != null)
    {
        foreach(DirectoryEntry child in de.Children)
        {
            PropertyCollection pc = child.Properties;
            IDictionaryEnumerator ide = pc.GetEnumerator();
            ide.Reset();
            while(ide.MoveNext())
            {
                PropertyValueCollection pvc = ide.Entry.Value as PropertyValueCollection;

                Console.WriteLine(string.Format("Name: {0}", ide.Entry.Key.ToString()));
                Console.WriteLine(string.Format("Value: {0}", pvc.Value));                
            }
        }      
    }  
}

See the value of PropertyValueCollection at runtime in the watch window to identify types of element, it contains & you can expand on it to further see what property each of the element has.

Adding to @JaredPar's code


PropertyCollection collection = GetTheCollection();
foreach ( PropertyValueCollection value in collection ) {
  // Do something with the value
  Console.WriteLine(value.PropertyName);
  Console.WriteLine(value.Value);
  Console.WriteLine(value.Count);
}

EDIT: PropertyCollection is made up of PropertyValueCollection
