    copied!<p>Edit:</p> <p>Of course my real code doesn't look exactly like this. I tried to write semi-pseudo code to make it more clear of whay I wanted to do.</p> <p>Looks like it just messed things up instead.</p> <p>So, what I actually would like to do is this:</p> <pre><code>Method&lt;Interface1&gt;(); Method&lt;Interface2&gt;(); Method&lt;Interface3&gt;(); ... </code></pre> <p>Well ... I thought that maybe I could turn it into a loop using reflection. So the question is: How how do I do it. I have <em>very</em> shallow knowledge of reflection. So code examples would be great.</p> <p>The scenario looks like this:</p> <pre><code>public void Method&lt;T&gt;() where T : class {} public void AnotherMethod() { Assembly assembly = Assembly.GetExecutingAssembly(); var interfaces = from i in assembly.GetTypes() where i.Namespace == "MyNamespace.Interface" // only interfaces stored here select i; foreach(var i in interfaces) { Method&lt;i&gt;(); // Get compile error here! } </code></pre> <p><br><br></p> <hr> <p>Original post:</p> <p>Hi!</p> <p>I'm trying to loop through all interfaces in a namespace and send them as arguments to a generic method like this:</p> <pre><code>public void Method&lt;T&gt;() where T : class {} public void AnotherMethod() { Assembly assembly = Assembly.GetExecutingAssembly(); var interfaces = from i in assembly.GetTypes() where i.Namespace == "MyNamespace.Interface" // only interfaces stored here select i; foreach(var interface in interfaces) { Method&lt;interface&gt;(); // Get compile error here! } } </code></pre> <p>The error I get is "Type name expected, but local variable name found". If I try</p> <pre><code>... foreach(var interface in interfaces) { Method&lt;interface.MakeGenericType()&gt;(); // Still get compile error here! } } </code></pre> <p>I get "Cannot apply operator '&lt;' to operands of type 'method group' and 'System.Type'" Any idea on how to get around this problem? </p>
