通过数字C＃定义文本框值

Question

我正在尝试以下代码，但结果为零！

textBox13.Text = (int.Parse(textbox1.Text) / 536).ToString ();

Answer 1

I believe you are expecting result set in 0.0... a double /float number. You may divide by 536.0 or 536d

textBox13.Text = (int.Parse(textbox1.Text) / 536d).ToString ();//or 536.0 

Currently your calculation is being done in integer type. You may cast either of the two oprands to type double/float.

Answer 2

That's because you do integer division.

Try

textBox13.Text = (double.Parse(textbox1.Text) / 536).ToString();

Answer 3

already answerd bu i'd suggest using TryParse

double d = 0;
if(double.TryParse(textbox1.Text,out d))
{
    textBox13.Text = (d/536.0).ToString();
}
else
{
   MessageBox.Show("There is no valid number in the textbox");
}
