I swear if this wasn't for a grade I would have trashed this...

Using a Data Grid View to add members for a Golf App. When I tried to read all members of a column into an array it bricked.

Source (Part)-

private void fullGameToolStripMenuItem_Click(object sender, EventArgs e)

    {

      foreach (string name in dgvPlayers.Columns["Names"])

      {

      }

Error-

foreach statement cannot operate on variables of type 'System.Windows.Forms.DataGridViewColumn' because 'System.Windows.Forms.DataGridViewColumn' does not contain a public definition for 'GetEnumerator'

I don't know much C#, but it looks like your error is occurring because you are trying to enumerate an object that doesn't have an enumerator.

A quick look at MSDN says that .Columns[] returns a DataGridViewColumn object, which does not contain a collection of the cells. What you'll probably want to do is enumerate through the .Rows collection instead.
