German UI Culture de-DE decimal changing to comma value issue in asp.net
提问by Kumar Gaurav
I am using german UI Culture in my asp.net application. I am changing my application's UI culture based on the language selected in the dropdown, on dropdown selected index change i am using this code
我在我的 asp.net 应用程序中使用德国 UI 文化。我正在根据下拉列表中选择的语言更改我的应用程序的 UI 文化，在下拉选择的索引更改中，我正在使用此代码
Thread.CurrentThread.CurrentCulture = new CultureInfo(this.lstLanguage.SelectedValue);
Thread.CurrentThread.CurrentUICulture = new CultureInfo(this.lstLanguage.SelectedValue);
the Dropdown is as below
下拉菜单如下
<asp:DropDownList cssClass="ddllanguage" ValidationGroup="b" runat="server" ID="lstLanguage" AutoPostBack="True" OnSelectedIndexChanged="LstLanguage_SelectedIndexChanged" meta:resourcekey="lstLanguage">
<asp:ListItem Value="en-US" Text="English" meta:resourcekey="ListItemResource2" ></asp:ListItem>
<asp:ListItem Value="de-DE" Text="Deutsch" meta:resourcekey="ListItemResource3"></asp:ListItem>
</asp:DropDownList>
My problem is after changing the language to de-DE all the decimal values in my application are being changed as comma, all the decimal number like 5.12 is coming as 5,12 all the decimal values are changed to comma. How to get decimal values as it is without comma.
我的问题是在将语言更改为 de-DE 后，我的应用程序中的所有十进制值都被更改为逗号，所有像 5.12 这样的十进制数都变成了 5,12，所有十进制值都更改为逗号。如何获得没有逗号的十进制值。

you can change number format info as per below code
您可以按照以下代码更改数字格式信息
Thread.CurrentThread.CurrentCulture.NumberFormat.NumberDecimalSeparator = ".";
try below code for parsing the decimal values as per culture.
尝试使用以下代码根据文化解析十进制值。
string str = "50,3";
Thread.CurrentThread.CurrentCulture = new CultureInfo("de-DE");
double d = double.Parse(str, Thread.CurrentThread.CurrentCulture.NumberFormat);
it gives result d = 50.3
它给出了结果 d = 50.3

Thread.CurrentUICultureis intended to be used for User Interface, it's the language used to display text, orientation and so on.Thread.CurrentCultureis intended to be used for parsing/formatting stuffs. Date and time, numbers and string comparison (for example).
Thread.CurrentUICulture旨在用于用户界面，它是用于显示文本、方向等的语言。Thread.CurrentCulture旨在用于解析/格式化东西。日期和时间、数字和字符串比较（例如）。
If you want to change only UI language (and to keep everything else with the culture of your web server) you have to modify only Thread.CurrentUICulture.
如果您只想更改 UI 语言（并保持其他所有内容与您的 Web 服务器的文化一致），您只需修改Thread.CurrentUICulture.

This behavior is correct for German. However, you might want to use . When serializing to XML, inserting to database, etc. for doing so you can format using invariant culture. You can learn more about Invariant Culture in the following link: What does CultureInfo.InvariantCulture mean
这种行为对德语来说是正确的。但是，您可能想要使用 . 在序列化为 XML、插入数据库等时，您可以使用不变区域性进行格式化。您可以在以下链接中了解有关不变文化的更多信息： CultureInfo.InvariantCulture 是什么意思
