Convert ArrayList into string array(string[]) in c#

A simple Google or search on MSDN would have done it. Here:

ArrayList myAL = new ArrayList(); 

// Add stuff to the ArrayList.
String[] myArr = (String[]) myAL.ToArray( typeof( string ) );

public static string[] Convert(this ArrayList items)
{
    return items == null
        ? null
        : items.Cast<object>()
            .Select(x => x == null ? null : x.ToString())
            .ToArray();
}

use .ToArray(Type)

string[] stringArray = (string[])arrayList.ToArray(typeof(string));

You can use CopyTo method of ArrayList object.

Let's say that we have an arraylist, which has String Type as Elements.

strArrayList.CopyTo(strArray)

Try do that with ToArray() method.

ArrayList a= new ArrayList(); //your ArrayList object
var array=(String[])a.ToArray(typeof(string)); // your array!!!
