自己写个函数,先从字符串中取出12.5,再除以100。

%不是一个数值字符啊
12.5% 要转换位0.125就可以了

各位的方法我当然是知道的,只是C#中的System.Globalization.NumberStyles.AllowTrailingSign是允许后缀的,
同时ystem.Globalization.NumberFormatInfo.InvariantInfo.PercentSymbol
表示后缀的许可字符,可以将数字转换为包含System.Globalization.NumberFormatInfo.InvariantInfo.PercentSymbol的string.为什么没有反向的?各位不觉得奇怪么?

首先要先取出12.5这个字符串,转化成数字,再除以100即可,代码如下:
string a="12.5%";
a=a.Substring (0,a.Length -1);
double b=Convert.ToDouble (a);
MessageBox.Show (b.ToString ());
