Question

Maybe I just don’t know .NET well enough yet, but I have yet to see a satisfactory way to implement this simple VB6 code easily in .NET (assume this code is on a form with N CommandButtons in array Command1() and N TextBoxes in array Text1()):

Private Sub Command1_Click(Index As Integer)     Text1(Index).Text = Timer  End Sub 

I know it’s not very useful code, but it demonstrates the ease with which control arrays can be used in VB6. What is the simplest equivalent in C# or VB.NET?

Make a generic list of textboxes:

var textBoxes = new List<TextBox>();  // Create 10 textboxes in the collection for (int i = 0; i < 10; i++) {     var textBox = new TextBox();     textBox.Text = 'Textbox ' + i;     textBoxes.Add(textBox); }  // Loop through and set new values on textboxes in collection for (int i = 0; i < textBoxes.Count; i++) {     textBoxes[i].Text = 'New value ' + i;     // or like this     var textBox = textBoxes[i];     textBox.Text = 'New val ' + i; }
