MultiLine Textbox to StringArray

This should do it.

String[] myStringArray = textBox1.Lines;

I am sorry, I meant ArrayList of type string

An ArrayList of Type String?  ArrayList are not strongly typed!  They accept Object.

If you want a strongly typed collection then use List<>:

so if I used List<string> myList.  How would I add the lines from a multi-line text box?
myList.Add(textbox) would add the whole text box and I want each line to be an item.
 

Like so:

            List<string> myList = new List<string>();
            myList.AddRange(this.textBox1.Lines);

Hehe...like mwvisa1 already posted.  =)

It is technically possible with ArrayList:
(and looks the same)

            ArrayList myList = new ArrayList();
            myList.AddRange(this.textBox1.Lines);

            foreach (string line in myList)
            {
                System.Diagnostics.Debug.Print(line);
            }

It's just not as "correct".  =)

Although ArrayList is not a strongly typed array you can still add the line from the text box like so:

            ArrayList myStringArray = new ArrayList();
            myStringArray.AddRange(textBox1.Lines);

Thanks for the help from everyone.  The answers were coming so quickly, but mwvisa1 was first to reply.
