<cannot view indexed property>

[Mike]

Hi,

I have created a collection of a custom class. Everything works fine (can add these items in a combo from within a VB.NET application, for instance), but when looking at the collection from a VB.NET application in the Watch window, I cannot see the items of the collection. The message in the Watch window's "value" says: "<cannot view indexed property>." Below is the code I wrote.

Any idea of what is wrong? Or is the error message "correct"?

Thanks a lot.
Mike


public class Companies : IEnumerable {

ArrayList m_oCompanies = null;

public Companies() { // Nothing is done in the constructor. }
public void Add(Company oCompany) {...}
public Company this[int index] {
get { return (Company)m_oCom panies[index]; }
}

public int Count { ... }

}

public IEnumerator GetEnumerator() { return new CompaniesEnumer ator(m_oCompani es); }

// Inner class implements IEnumerator interface:
class CompaniesEnumer ator : IEnumerator {

int index;
ArrayList m_oCompanies;

public CompaniesEnumer ator(ArrayList oCompanies) { this.m_oCompani es = oCompanies; }

public bool MoveNext() { return (++index < m_oCompanies.Co unt); }

public object Current {
get {
if (index < m_oCompanies.Co unt) return m_oCompanies[index];
else
return null; }
}

public void Reset() { ... }

Mike,

The watch window cannot view properties that have an indexer. If you need to
see the contents of an indexed property, specify the index as part of the
watch.

e.g.

m_oCompanies.It em(0)

You'll get an exception if the index you specify is out of range.

On a side note, I didn't know you could compile C# code with VB.net ;) (your
source is c#, but your post refers to VB)

HTH,

Trev.
