C# insert a variable
<p>I have this code, where i have an arrayList. I use the method arrayList.Contains.</p>

<pre><code> if (arrayList2.Contains(5))
 {
     //something
 }
</code></pre>

<p>I would like to replace arrayList2 in the code, with a variable (a string for example) that contains the value arrayList2.</p>

<pre><code>string hello = "arrayList2" // create a varible with the value of the name of the arrayList
if (hello.Contains(5)) // insert the variable "hello" instead of "arrayList2"
{
    //something
}
</code></pre>

<p>This method doesn't work, any ideas how i can get it to work?</p>
