double txtnum = Convert.ToDouble(this.textBox1.Text);
if (txtnum < 0)
{
txtnum = Math.Round(txtnum + 5 / Math.Pow(10, 3), 2, MidpointRounding.AwayFromZero);
}
else
{
txtnum = Math.Round(Convert.ToDouble(txtnum), 2, MidpointRounding.AwayFromZero);
}
MessageBox.Show(txtnum.ToString());
if (txtnum < 0)
{
txtnum = Math.Round(txtnum + 5 / Math.Pow(10, 3), 2, MidpointRounding.AwayFromZero);
}
else
{
txtnum = Math.Round(Convert.ToDouble(txtnum), 2, MidpointRounding.AwayFromZero);
}
MessageBox.Show(txtnum.ToString());

private double GetSiSheWuRuNumber(double d, int pointBits)
{
return Math.Round(d, pointBits,MidpointRounding.AwayFromZero);
}
使用：double dd = GetSiSheWuRuNumber(12.553, 2);
结果 dd=12.55
{
return Math.Round(d, pointBits,MidpointRounding.AwayFromZero);
}
使用：double dd = GetSiSheWuRuNumber(12.553, 2);
结果 dd=12.55
