Join an ArrayList

[Guest]

I need to join the elements of an arraylist into a comma delimited list and
have been doing the following

string[] x = new string[myArrayList.Count];
myArrayList.CopyTo(x);
string.join(",",x);

I tried string.join(",",myArrayList.ToArray(typeof(string))); but the
compiler complained about converting from an object to a string array.

Is there another, i.e. shorter, way to do this?

Did you try

String.Join(",", (string[])myArrayList.ToArray(typeof(string)));

?

Hi kevin,

ok, if you have an ArrayList then use this to
get a (joined) string "s" from it:

string s = string.Join(",", myArrayList.ToArray(typeof(string)) as
string[]);
