How to populate

List<TextBox> textBoxList = new List<TextBox>();

Is it possible to populate to textBoxList with 5 textboxes and the text the boxes contain say

textBox1.Text
textBox2.Text
textBox3.Text
textBox4.Text
textBox5.Text

and then I’m planning to populate this like

for(int i=1;i<6;i++)
 {   //x is a string collection
    x[i]=textBox[i].Text= // some action
 }

Your question is “is it possible”? Answer: Yes, it is.

How? Well, you need to add your textboxes to your List before you can reference them:

textBoxList.AddRange( { textBox1, textBox2, textBox3, textBox4, textBox5 } );

OR

textBoxList.Add(textBox1);
textBoxList.Add(textBox2);
textBoxList.Add(textBox3);
