Try something like
<br />
string[] sArray = (string[])pArrayList.ToArray(typeof(string));<br />
string Result = string.Join(sSeparator, sArray, 0, sArray.Length);<br />

You may get this exception if your ArrayList contains values other than strings. Is that the case? If yes, try changing the code above this way:

object[] pArray = pArrayList.ToArray();
string Result = string.Join(sSeparator, pArray);

Good Call.
use

string str = arr.Cast<string>().Aggregate((str1, str2) => str1 + "," + str2);


will give you comma seprated string but make sure that your arraylist contains all the string

It worked. But it is combining all the value after the another.
