Equivalent to refer to control by variable name?

Question

In VB I can loop through controls, or refer to a control by concatenating a variable to a string. Something like:

Dim I as integer
I = 1
Me[\"Textbox\" & I]         


        

Answer 1

int i = 1;
this.Controls["TextBox" & i].Text = "Some text";

The above code is assuming that it is in a Control/Form.
