Arrays and inheritence


I have a class called StatusType.

public class StatusType: ICloneable, IComparable<StatusType>
int id; // id as stored in statusType table
public int Id
get { return id; }
I also have a class called StatusTypes which looks something like this

public class StatusTypes: ICloneable, IEnumerable
StatusType[] statusTypes;

public StatusType this[int statusTypeId] // Indexer
foreach (StatusType statusType in statusTypes)
if (statusType.Id == statusTypeId)
return statusType;
return null;

public int Length{get { return statusTypes.Length; }}

// returns "P/F/A" for Passed, Failed, Aborted status types
public string StringRepresentation
string returnString = "";

if (statusTypes.Length 0)
returnString =

for(int i=1;i<statusTypes.Length;i++)
returnString += @"/" +

return returnString;

// populate from the statusType table
public StatusTypes(dataSet.statusTypeDataTable statusType)
statusTypes = new StatusType[statusType.Count];

int index = 0;
foreach (DataRow statusTypeDataRow in statusType.Rows)
statusTypes[index++] = new
StatusType(statusTypeDataRow as dataSet.statusTypeRow);

public object Clone()
StatusTypes clonedStatusTypes =

clonedStatusTypes.statusTypes = new

int index = 0;
foreach (StatusType statusType in statusTypes)
clonedStatusTypes.statusTypes[index++] =

return clonedStatusTypes;

IEnumerator IEnumerable.GetEnumerator() { return
statusTypes.GetEnumerator(); }


Since I'm still learning C#, is this implementation reasonable? One
thing I'm wondering about is the fact that I have a public accessor to
StatusType:id. The fact is that this is only accessed by StatusTypes.
It feels to me that StatusTypes should have access to private or
protected members of StatusType since this feel like a kind of
inheritance to me. How would I implement this?
