什么格式双必须？ [英] What format double must be?

问题描述

我尝试添加到double类型的List元素：

I try add to double type List element:

CurrentValues.Add(double.Parse(name.InnerText)); //15.9933

但我收到错误：



{输入字符串无效。}

name.InnerText必须是什么格式？

谢谢

But i get error:

{"Input string was invalid."}
What format name.InnerText must be?
Thank you

推荐答案

只需尝试相反的方法，看看结果如何：

Just try the other way around to see what the result is:

String.Format("{0}", 15.9933)

祝你好运！

Good luck!

取决于 - 机会是InnerText属性包含一些包装器信息（可能是HTML，但不知道它是什么控件，我无法分辨） - 所以请改用Text属性！

Depends - the chances are that the InnerText property contains some wrapper information (possibly HTML but without knowing what control it is I can''t tell) - so use the Text property instead!

假设CurrentValues类似于

Assuming that CurrentValues are something like

List<double> CurrentValues = new List<double></double></double>

您可能有小数位错误，所以你可以使用不变的文化内容：

You could have a decimal place wrong, so you could use invariant culture insead:

double.Parse(name.InnerText, CultureInfo.InvariantCulture)

您还应检查InnerText是否为空。

You should also check to see if InnerText is not empty.
