限制小数位数 [英] Limiting the decimal Places

问题描述

有没有办法将小数位数限制为2？ 

Is there a way to limit the decimal places to just 2? 

/*Set the variable to 0 */
_bmiVal = 0;
/*Equation*/
_bmiVal = (_weight / Math.Pow(_inchesVal + _heightVal * 12, 
2)) * 703;
/*Place the answer in the WPF text box as a string*/
txtBMI.Text = _bmiVal.ToString();

推荐答案

您好，

尝试以下

<TextBox Text="{Binding Value, StringFormat=N2}" />
<TextBox Text="{Binding Value, StringFormat={}{0:#,#.00}}" />
