passing array via query string
<p>I am passing a javascript array via <code>Request.QueryString["cityID"].ToString()</code>, but it shows me an error of  "invalid arguments":</p>

<pre><code>blObj.addOfficeOnlyDiffrent(Request.QueryString["cityID"].ToString(),
                            Request.QueryString["selectTxtOfficeAr"].ToString());
</code></pre>

<p>The method declaration looks like:</p>

<pre><code>public string addOfficeOnlyDiffrent(string[] cityID, string selectTxtOfficeAr) { }
</code></pre>
