<p>In a <a href="https://stackoverflow.com/questions/9033#9099">question answer</a> I find the following coding tip:-</p>

<p>2) simple lambdas with one parameter:</p>

<pre><code>x =&gt; x.ToString() //simplify so many calls
</code></pre>

<p>As someone who has not yet used 3.0 I don't really understand this tip but it looks interesting so I would appreciate an expantion on how this simplifies calls with a few examples.</p>

<p>I've researched lambdas so I <strong>think</strong> I know what they do, however I <strong>may</strong> not fully understand so a <strong>little</strong> unpacking might also be in order.</p>

This basically expands to:
```
```
private string Lambda(object x) {
  return x.ToString();
}
```
```
