Question

For example in Windows Form, you have textboxes textbox0 to textbox29 and you need to assign them all to an array. What I currently can think of is to do this:

array[0] = textbox0;
array[1] = textbox1;
...
array[29] = textbox29;

Is it possible for me to do something like this:

for(int i=0; i<30; i++)
{
    array[i] = textbox + i; 
    //and some magic is done such tt this is a variable, eg. textbox1
}

I am modifying @rdkleine code

Control[] array = new Control[100];
foreach (Control c in FormX.Controls)
{
    int index;
    if (c.Name.StartsWith("textbox") && int.TryParse(c.Name.Substring(7),out index))
    {
        array[index] = c;
    }
}

I think this should place the controls in the correct index in the array.
