Accepted answer
in that case instead of int.Tryparse
do double.tryparse(textbox.Text, out (your variable (make sure it's declared as double as well))
Hope this helps

try something like this keep in mind i am using integers here. you may change it based on your data type.
bool isAValid = int.TryParse(textbox1.Text, out a);
bool isBValid = int.TryParse(textbox2.Text, out b);
if (isAValid && isBValid)
{
label.Text = (a + b).ToString();
}
