How to specify default value for List<> parameter in a c# function?
<p>I've got a C# method that takes a bunch of parameters, all of which have default values. One of the parameters is a List. I can't figure out how to specify that the List should default to empty. Here's what it looks like:</p>

<pre><code>    public static void execute(
        String condition = "Unnamed condition",
        List&lt;String&gt; messages,
        Object actual    = null,
        Object expected  = null)
</code></pre>

<p>I can't quite figure out how to specify that messages should be empty by default. When I enter:</p>

<pre><code>...
List&lt;String&gt; messages = new List&lt;String&gt; ()
...
</code></pre>

<p>it complains that "default parameter value for 'messages' must be a compile-time constant".</p>

<p>Any ideas?</p>
