%不是一个数值字符啊
12.5% 要转换位0.125就可以了

自己写个函数，先从字符串中取出12.5，再除以100。

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 ());

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？
