ASP.Net:如何将一个百分比字符串转换为数值

string percent="50%";
怎么将它转换为数值型变量，让它等于0.5?

Answer 1

string percent = "50%";
string p = percent.Substring(0, 2);
double p1 = int.Parse(p)*0.01;

Answer 2

思路，取%左边所有的字符串，转换成数字格式做除法运算。

Answer 3

string percent = "50%";
string p = percent.TrimEnd("%");
double p1 = int.Parse(p)*0.01;
