C# IF /ELSE create directory problem
<p>I'm gettign the error: Error    2 Only assignment, call, increment, decrement, and new object expressions can be used as a statement.</p>

<p>Here is the code:</p>

<pre><code>string masterdin = (@"K:\Drams\Cluse\" +"\\"+"Aia_Gn"+"\\"+Environment.UserName+"\\"+textBox1.Text);
        if(Directory.Exists(masterdin))
        {
            MessageBox.Show("This Export set already exists, please rename your Export set");
            textBox1.Clear();

        }
        else(System.IO.Directory.CreateDirectory(masterdin));
</code></pre>

<p>The error exists on this line : else(System.IO.Directory.CreateDirectory(masterdin));</p>

<p>Can someone point out how to make this work?</p>
