DataColumnCollection class has a columnFromName field that is defined as Dictionary of string and DataColumn as shown below
public sealed class DataColumnCollection : InternalDataCollectionBase {
private readonly DataTable table;
private readonly ArrayList _list = new ArrayList();
private int defaultNameIndex = 1;
private DataColumn[] delayedAddRangeColumns;
private readonly Dictionary<string, DataColumn> columnFromName;
....
When I see this object in memory, its shown as a Hashtable (image below).
I have used Dictionary object in many applications that are shown as Dictionary in Windbg/Sos also. How come this Dictionary is getting translated into a Hashtable?
