我有一个简单的问题，小数解析。下面code正常工作，我的电脑上，但是当我发布项目在服务器上（VPS，在Windows Server 2008 R2标准版），我得到的错误输入字符串的格式不正确。任何想法有什么不对？

我店，在MySQL数据库表分析号码 - 列类型为 DECIMAL（10,4）

来源$ C ​​$ C：

 的CultureInfo nonInvariantCulture =新的CultureInfo（EN-AU）; //或PL-PL
nonInvariantCulture.NumberFormat.NumberDecimalSeparator =。;
Thread.CurrentThread.CurrentCulture = nonInvariantCulture;
串toConvert =（3,4589）更换（，，。）。 //这是一个例子
十进制解析= decimal.Parse（toConvert）;
 

解决方案

如果您知道该字符串重新数presentation使用逗号作为小数点分隔符，你可以使用自定义解析值的NumberFormatInfo ：

  VAR数=3,4589;
VAR的NumberFormatInfo =新的NumberFormatInfo（）;
numberFormatInfo.NumberDecimalSeparator =，;
VAR值= Decimal.Parse（数的NumberFormatInfo）;
 

您也可以使用的CultureInfo ，你知道会工作，但我认为这是比较容易理解。

如果在另一方面号码的格式为： 3.4589 您可以简单地使用 CultureInfo.InvariantCulture 您可以考虑一种基于的en-US 默认文化：

  VAR数=3.4589;
VAR值= Decimal.Parse（数量，CultureInfo.InvariantCulture）;
 

I have a simple problem with decimal parsing. The following code works fine on my computer but when I publish the project on the server (VPS, Windows Server 2008 R2 standard edition) I get the error "Input string was in incorrect format." Any ideas what's wrong?

I store that parsed number in the MySQL DB table - the column type is DECIMAL(10, 4)

Source Code:

CultureInfo nonInvariantCulture = new CultureInfo("en-AU"); //or pl-PL
nonInvariantCulture.NumberFormat.NumberDecimalSeparator = ".";
Thread.CurrentThread.CurrentCulture = nonInvariantCulture;
string toConvert = ("3,4589").Replace(",", "."); //it's an example
decimal parsed = decimal.Parse(toConvert);

If you know that the string representation of the number uses comma as the decimal separator you can parse the value using a custom NumberFormatInfo:

var number = "3,4589";
var numberFormatInfo = new NumberFormatInfo();
numberFormatInfo.NumberDecimalSeparator = ",";
var value = Decimal.Parse(number, numberFormatInfo);

You can also use a CultureInfo that you know will work but I think this is easier to understand.

If on the other hand the format of the number is 3.4589 you can simply use CultureInfo.InvariantCulture which you can consider a kind of "default" culture based on en-US:

var number = "3.4589";
var value = Decimal.Parse(number, CultureInfo.InvariantCulture);
