    text
    copied!<p>I want to create a class which implements IEnumerable&lt;T&gt; but, using reflection, generates T's and returns them via IEnumerable&lt;T&gt;, where T' is a entirely constructed subclass of T with some properties hidden and others read-only. </p> <p>Okay., that might not be very clear. Let me explain this via the medium of code - I'd like to have a class CollectionView&lt;T&gt; as follows:-</p> <pre><code>public class CollectionView&lt;T&gt; : IEnumerable&lt;T&gt; { public CollectionView(IEnumerable&lt;T&gt; inputCollection, List&lt;string&gt; hiddenProperties, List&lt;string&gt; readonlyProperties) { // ... } // IEnumerable&lt;T&gt; implementation which returns a collection of T' where T':T. } ... public class SomeObject { public A { get; set; } public B { get; set; } public C { get; set; } } ... var hiddenProperties = new List&lt;string&gt;(new[] { "A" }); var readOnlyProperties = new List&lt;string&gt;(new[] { "C" }); IEnumerable&lt;SomeObject&gt; someObjects = CollectionView&lt;SomeObject&gt;(hiddenProperties, readOnlyProperties); ... dataGridView1.DataSource = someObjects; </code></pre> <p>(When displayed in dataGridView1 shows columns B and C and C has an underlying store which is read-only)</p> <p>Is this possible/desirable or have I completely lost my mind/does this question demonstrate my deep inadequacy as a programmer?</p> <p>I want to do this so I can manipulate a collection that is to be passed into a DataGridView, <em>without having to directly manipulate the DataGridView to hide columns/make columns read-only</em>. So no 'oh just use dataGridView1.Columns.Remove(blah) / dataGridView1.Columns[blah].ReadOnly = true' answers please!!</p> <p>Help!</p>
