double.TryParse在荷兰 [英] double.TryParse in dutch

问题描述

Web服务器在荷兰语（比利时）运行

Web server running in Dutch(Belgium)

double output;

double.TryParse(txtTextbox1.Text, out output);

这是将文本转换在荷兰环境翻番的好办法？比方说，输入 24.45 而不是 24,45

Is this a good way to convert text to double in dutch environment? Let's say the input is "24.45" instead of "24,45"

推荐答案

如果您想使用荷兰语（比利时）号格式：

If you want to use the Dutch (Belgium) number format:

double output;
double.TryParse("24,45", NumberStyles.Any, CultureInfo.GetCultureInfo("nl-BE"), out output);

或者用美国的数字格式：

Or to use the US number format:

double output;
double.TryParse("24.45", NumberStyles.Any, CultureInfo.GetCultureInfo("en-US"), out output);

如果你试图解析24.45与荷兰文化集，你会得到2445 同样，如果你试图解析24,45与美国的文化，你会得到2445。如果你想解析失败如果使用了错误的小数点，更改NumberStyles.Any排除标志： NumberStyles.AllowThousands ：

If you attempt to parse "24.45" with a Dutch culture set, you'll get back "2445", similarly, if you attempt to parse "24,45" with a US culture, you'll get "2445". If you want the parse to fail if the wrong decimal point is used, change NumberStyles.Any to exclude the flag: NumberStyles.AllowThousands:

double output;
if (double.TryParse("24.45", NumberStyles.Any ^ NumberStyles.AllowThousands, CultureInfo.GetCultureInfo("nl-BE"), out output))

如果您的整个应用程序在荷兰，你应该在全球范围改变你的CultureInfo - 的这里是如何做到这一点在的WinForms 和是如何做到这一点在ASP 。.NET

If your entire application is in Dutch, you should change your cultureinfo globally - here's how to do it in WinForms and here's how to do it in ASP.NET.

在您使用的是全局设置的CultureInfo，您可以更改上面的代码：

Once you're using a globally set CultureInfo, you can change the above code to:

double output;
double.TryParse("24.45", NumberStyles.Any, CultureInfo.CurrentCulture, out output);
