A lot of the above work. Just to add. If your textboxes are not directly on the form but are on other container objects like a GroupBox, you will have to get the GroupBox object and then iterate through the GroupBox to access the textboxes contained therein.

foreach(Control t in this.Controls.OfType())
{
   foreach (Control tt in t.Controls.OfType())
   {
        // do stuff
   }
}
