The textbox1.Text can't copy the textbox2.Text value from another form

Question

Below is my code

private void btnCptKb5_Click(object sender, EventArgs e)
{ 
   Form1 form1 = new Form1();
   textbox1.text = form1.textbox1.text;
}

Why is that I can't copy the value of form1 textbox?

It's not really clear what you're trying to achieve here. What do you mean by not being able to copy? — Szymon, Jan 21 '14 at 04:34
You've created the form but done nothing else - what are you expecting to copy? Have you populated the textbox with a value? — slugster, Jan 21 '14 at 04:37
I think...the above code won't compile, do you want to say Form1 form1 = new Form1()? By the way, form1 is a new object which contains no data — User2012384, Jan 21 '14 at 04:37
sorry for my english. the btnCptKb5_Click is from form 2 and I want to copy the value I inputted from form1 textbox? How can I do it? — Lucas Juan, Jan 21 '14 at 04:39

You didn't change Textbox2.Text value
You are creating a completely new form instance,and trying to access that form's textbox value.It will be always empty even if your code works.
