How to convert ArrayList into string array(string[]) in c#

Question

How can I convert ArrayList into string[] in C#?

Answer 1

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)

Answer 2

Try do that with ToArray() method.

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

Answer 3

use .ToArray(Type)

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

Answer 4

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 ) );

Answer 5

string[] myArray = (string[])myarrayList.ToArray(typeof(string));

Answer 6

Another way is as follows.

System.Collections.ArrayList al = new System.Collections.ArrayList();
al.Add("1");
al.Add("2");
al.Add("3");
string[] asArr = new string[al.Count];
al.CopyTo(asArr);
