Question

I have an array being returned but as I’m new to programming I can’t work out how to read each value. Can someone please point me in the right direction?

My code is below.

private void testToolStripMenuItem_Click(object sender, EventArgs e) {  foreach (int name in getNames()) //<----I'm wrong here I guess  {     MessageBox.Show(name.ToString());  } }  private ArrayList getNames() {  //some code...  ..  ...  return names; } 

Thanks all

Firstly, you’re not returning an array, but rather an ArrayList instance. Secondly, why would a name be an int? Surely you mean string? Finally, if you’re on .NET 2.0 or later, you can use generics to improve your code. So, use List<string> rather than ArrayList.

private void testToolStripMenuItem_Click(object sender, EventArgs e) {     foreach (string name in getNames())     {         MessageBox.Show(name);     } }  private List<string> GetNames() {     var names = new List<string>();     names.Add('Kent');     return names; }
