Question

I have two buttons to reduce or increase the number. Also, I have a label which is has value zero. How can I increase or decrease without giving zero value to the Label in C#?

Code:

int sayi = int.Parse(lbltext1.Text);

sayi = sayi - 1;

lbltext1.Text = sayi.ToString();

Answer 1

Try something like this…(not tested)

void IncreaseBtn_Click(Object sender, EventArgs e)
{
    var value = this.myLabel.Text;
    var intValue = 0;
    Int32.TryParse(value, out intValue);
    this.myLabel.Text = (++intValue).ToString();
}

void DecreaseBtn_Click(Object sender, EventArgs e)
{
    var value = this.myLabel.Text;
    var intValue = 0;
    Int32.TryParse(value, out intValue);
    this.myLabel.Text = (--intValue).ToString();
}
