我想将数字四舍五入到最接近的50的倍数
例如:如果
数是34
结果0
或
人数= 76
结果50
或
数= 345

Like this,I wanna round of a value of txtbox1 by clicking calcButton

推荐答案

Well，如果将34舍入为最接近的50的倍数，那么就舍入为txtbox1的值，而不是0.

但是，如果您想按照示例中的建议进行四舍五入-只需除以50，然后再使用整数再乘以50.容易吧?

Well, if you round 34 to the nearest multiple of 50, you''d get 50, not 0.

But if you want to round down as suggested by your examples - just divide by 50, then multiply by 50 again using integers. Easy huh?

protected void Button1_Click(object sender, EventArgs e)
   {
       if ((int.Parse(TextBox1.Text) / 50) * 50 < int.Parse(TextBox1.Text))
       {
           TextBox1.Text=(int.Parse(TextBox1.Text) / 50 * 50).ToString();
       }
   }
