我读从我的App.config的值;这就是：

I am reading a value from my App.config; which is:

 <add key="someValue" value="0.05"/>

和我尝试将其转换为加倍做：

And I try to convert it to double by doing:

 var d = double.Parse(ConfigurationManager.AppSettings["someValue"]);

和我获得0.05 5.0 insteads。

And I obtain 5.0 insteads of 0.05.

你能指点？我该怎么办错了，我应该怎么分析呢？

Can you advice? What do I do wrong and how should I parse this?

推荐答案

这对你的文化设置，测试相同，但有一个逗号，而不是一个点，你会看到这项工作的

That's for your culture settings, Test the same but with a comma instead a point and you will see that work's

var d = double.Parse("0,05");

要修复这个问题，你可以用来解析函数的后续超载

To fixed this problem you could used the follow overload of the parse function

var d = double.Parse(ConfigurationManager.AppSettings["someValue"], CultureInfo.InvariantCulture);
