Check if all List Items have the same member value in C#
<p>I'm searching for a simple and fast way to check if all my Listitems have the same value for a member.</p>

<pre><code>foreach (Item item in MyList)
{
    Item.MyMember = &lt;like all other&gt;;
}
</code></pre>

<p><strong>EDIT:</strong>
I forgot one thing: If one of this members (its a string) is String.Empty and all other items have the same string it should be true too! Sorry i forgot this.</p>
