    <p>is it possible to call with reflection a method with "explict type argument" <code>&lt;S&gt;</code> definition<br> e.g. <code>oObject.Cast&lt;S&gt;()</code> ?</p> <p>where is:</p> <pre><code>IList &lt;P&gt; oObject = new List &lt;P&gt;(); </code></pre> <p>I tried with</p> <pre><code>oObject.getType().InvokeMember( "Cast", BindingFlags.InvokeMethod, null, oObject, null) </code></pre> <p>but it does not work, does anyone know why?</p> <hr> <p>Here is the complete test code but still it does not work. The last line produce always exception. Is it possible to make it work ?</p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Reflection; namespace reflection_tester { class CBase { public string Ja = "I am the base"; } class MyClass01 : CBase { public string _ID; public string ID { get { return _ID; } set { _ID = value; } } } class Program { public static object wrapper() { //return a list of classes MyClass01 IList&lt;MyClass01&gt; lstClass01 = new List&lt;MyClass01&gt;(); MyClass01 oClass01a = new MyClass01(); oClass01a.ID = "1"; MyClass01 oClass01b = new MyClass01(); oClass01b.ID = "2"; lstClass01.Add(oClass01a); lstClass01.Add(oClass01b); return lstClass01; } static void Main(string[] args) { MyClass01 oMy1 = new MyClass01(); oMy1._ID = "1"; MyClass01 oMy2 = new MyClass01(); oMy2._ID = "3"; IList&lt;MyClass01&gt; oListType01 = new List&lt;MyClass01&gt;(); oListType01.Add(oMy1); oListType01.Add(oMy2); object oObjectType = new object(); oObjectType = oListType01; /* this works */ IEnumerable&lt;CBase&gt; enumList = oListType01.Cast&lt;CBase&gt;(); MethodInfo mInfo = typeof(System.Linq.Enumerable).GetMethod("Cast", new[] { typeof(System.Collections.IEnumerable) }).MakeGenericMethod(typeof(CBase)); /* this does not work, why ? throws exception */ IEnumerable&lt;CBase&gt; enumThroughObject = (IEnumerable&lt;CBase&gt;)mInfo.Invoke(oObjectType, null); return; } } } </code></pre>

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.
