==Use the BinarySearch() method to search charArray for "o"==

<source lang="csharp">using System;
class MainClass
{

int index = Array.BinarySearch(charArray, "o");
Console.WriteLine("Array.BinarySearch(charArray, "o") = " + index);
}
}</source>
<pre class=codeResult>Array.BinarySearch(charArray, "o") = 5</pre>
