I'm working on a windows form application and I have a button and a textbox in it.

When the button is pressed, it should make the textbox visible and hidden.

回答1:

myTextbox.Visible = !myTextbox.Visible;

回答2:

Did you try Google?

textBox1.Visible = false;

You can toggle the visibility by doing:

if(textBox1.Visible == true)
    textBox1.Visible = false;
else
    textBox1.Visible = true;

WinForm:

private void button1_Click(object sender, System.EventArgs e)
{
    textBox.Visible = !textBox.Visible;
}

WPF:

private void button1_Click(object sender, RoutedEventArgs e)
{
        if (textBox.Visibility != System.Windows.Visibility.Hidden)
            textBox.Visibility = System.Windows.Visibility.Hidden;
        else
            textBox.Visibility = System.Windows.Visibility.Visible;
}

You can find an example here

private void button1_Click(object sender, System.EventArgs e)
{
   /* If the CTRL key is pressed when the 
      * control is clicked, hide the control. */ 
   if(Control.ModifierKeys == Keys.Control)
   {
      ((Control)sender).Hide();
   }
}

回答5:

textbox.visible=true;

you should try this on buttonClick event
