Accepted answer
total = total + i; use this code for total value.

i try but doesn't work

private void txtinput_KeyPress(object sender, KeyPressEventArgs e)
{
if (!(Char.IsDigit(e.KeyChar) || (e.KeyChar == (char)Keys.Back)))
{
int a = Convert.ToInt32(txtinput.Text);
// var str = array.join(',');
// int a = Convert.ToInt32(txtinput.Text);
for (int i = a; i >= 1; i--)

You need to take an array and assign values in it. Then from that you can print it. See below examples, https://www.codecademy.com/forum_questions/554e20bf76b8fee454000274 https://www.tutorialspoint.com/how-to-print-the-contents-of-array-horizontally-using-chash

int total = 0;
int a = Convert.ToInt32(txtnumber.Text);

{
listBox1.Items.Add(i);

}
e.Handled = true;

Check this for loop example, https://www.dotnetperls.com/for#:~:text=Decrement%20loop.,0%20and%20can%20process%20it. In the for loop you can assign value to listbox as well as calculate the total value. Thanks

First take a textbox and apply key press event in it. Then by using for loop or foreach loop assign each value in listbox and sum all the values and display in total. The same way you can do it for 2nd problem. Check this link for example, https://www.c-sharpcorner.com/UploadFile/736bf5/keypress-event-in-C-Sharp/
