How to convert string array to long array?
<p>I am in bust at the moment, I have this string array:</p>

<pre><code>string[] StringNum = { "4699307989721714673", "4699307989231714673", "4623307989721714673", "4577930798721714673" };
</code></pre>

<p>I need to convert them To long array data type in C#:</p>

<pre><code>long[] LongNum= { 4699307989721714673, 4699307989231714673, 4623307989721714673, 4577930798721714673 };
</code></pre>

<p>But I have no idea how, is it even possible? </p>
