Body
The methods on <a href="http://docs.oracle.com/javase/6/docs/api/java/util/Enumeration.html" rel="nofollow"><code>Enumeration<E></code></a> look like they achieve similar purposes to the <a href="http://msdn.microsoft.com/en-us/library/78dfe2yb.aspx" rel="nofollow"><code>IEnumerator<T></code></a> interface in C#, but with slightly different semantics. The <a href="http://msdn.microsoft.com/en-us/library/system.collections.ienumerator.movenext.aspx" rel="nofollow"><code>MoveNext()</code></a> method, for example, fulfills both purposes: it moves to the next element and returns a boolean to tell you whether there was a next element to move to. But I find it highly unlikely that you really need this interface. Can you share more details about what you're trying to achieve? It's often possible to write much nicer C# code than you'd get doing a straight-across conversion. <h3>Update</h3> Ack! My eyes! Okay, so this is antiquated (or just poorly done) Java code in the first place. Instead of: <pre><code> Enumeration objEnum = null; for (objEnum=objStructureHT.keys(); objEnum.hasMoreElements();){ String strFieldName = (String)objEnum.nextElement(); </code></pre> It should be: <pre><code> for (String strFieldName : objStructureHT.keys()){ </code></pre> Which translates nicely in C# to (assuming you're using a <code>Dictionary<string, string></code> for <code>objStructureHT</code>: <pre><code> foreach (string strFieldName in objStructureHT.Keys){ </code></pre> However, the only reason you're even getting the <code>Keys</code> is so that you can look up each one and get its value too, right? So there's a better way: <pre><code> foreach (var pair in objStructureHT){ string strFieldName = pair.Key; string strDataType = pair.Value; ... </code></pre> ... which makes one wonder why we're even using a <code>Dictionary</code> instead of a class with <code>FieldName</code> and <code>DataType</code> properties. But that's getting beyond the scope of this question. Does this all make sense?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
