Question

Is it possible to itterate directly over properties of the objects stored within a Dictionary collection in C#?

For example, I have a Dictionary called Fields of type Dictionary<String, Field>. The Field object has a property of Data which is of type XmlDataDocument so I would like to do something like,

foreach(XmlDataDocument fieldData in Fields.Values.Data){

}

I know it’s pretty trivial since all I would need to do when itterating over Field objects instead would be,

XmlDataDocument fieldData = field.Data;

within the Field itteration however if there is a quicker way to do it I’d like to know 🙂

Answer 1

In C# 3.0:

foreach (var data in Fields.Values.Select(x => x.Data))
{
}

It’s not any “quicker” though.
