Static readonly string arrays
<p>I am using static readonly string arrays in my web application. 
Basically array is having error codes and i have kept all similar error codes in one array and checking this array instead of checking each one in different constant string. </p>

<p>like </p>

<pre><code>public static readonly string[] myarray = string[] {"232132132","31232132","123123123"}
</code></pre>

<p>Please let me know is there any harm in using static readony string arrays ? </p>

<p>Note : I am not facing any error, wanted to know is there any harm or performance issue for using like this?  </p>
