How to modify the attributes of a file with no extension in C#?
<p>This is my code</p>

<pre><code>static string pat = "C:\\" + System.Environment.UserName + 
              "\\AppData\\Local\\Google\\Chrome\\User Data\\Default\\History";
FileInfo hist = new FileInfo(pat);
</code></pre>

<p>Here <code>History</code> is a file, with no extension.
All I want to do is this:</p>

<pre><code>hist.IsReadOnly = true;
</code></pre>

<p>But <code>directorynotfoundexception</code> comes. Please help me, how do I access the <strong>file</strong>, it thinks that History is a directory! </p>
