Why doesn't this work?!

I need to fill the lines of a multiline TextBox with the contents of a ListArray.

I have a TextBox on a form, with properties set as follows:

Name = txtErrors

MultiLine = true

AcceptsReturn = true

AcceptsTab = true

In my code, I do the following:

private ArrayList myErrorList = new ArrayList(100);

// The array is filled elsewhere with error messages

txtErrors.Lines = new string[myErrorList.Count];

myErrorList.CopyTo(txtErrors.Lines);

My code compiles, but the multiline text box is empty, although the myErrorList ArrayList has 3 entries in it (as seen during debugging). Why isn't this working

Thank you very much, it's working now.

Can you please explain why

Thanks again,

well you are going through each element of the array, the array containing the values, so when you go through each element of the array, you are getting the value and appending to the textbox following by a newline.

the CopyTo copies the array collection into another array, which may/may not work - it's just better doing it as above so you know exactly what's going on

try this way

foreach(string currentElement in myErrorList)

{

this.txtErrors.Text += currentElement + Environment.NewLine;

}
