Why doesn't this code compile?

[Dave]

This code generates the following error:

Error 2 Cannot convert type
'System.Collections.Generic.KeyValuePair<string,CollectionTest.Group>' to
'CollectionTest.Group' C:\Code\Project\CollectionTest.cs 21 4 Project

How do I use foreach to iterate through the Groups collection??



public class Group
{
}

public class Groups : SortedList<string, Group>
{
}

public class TestIt
{
public void Test()
{
Groups groups = new Groups();

foreach (Group group in groups)
{
}
}
}

Perhaps you want

foreach (Group group in groups.Values)
{
,,,
}

 

[Dave]

Ok, needed to use groups.Values instead of just groups.

foreach (Group group in groups.Values)

Yes. If you iterate over a Dictionary type (SortedList, Hashtable)
directly, what you get back is some sort of dictionary entry that
comprises a key and a value.

If you want just the values (or, perhaps, just the keys), you have to
say that explicitly.
