将字符串转换为十进制奥秘 [英] Convert String to Decimal Mystery

问题描述

我面临使用C＃.NET从字符串转换为十进制的问题。问题是我已经编写了以下代码，并且在开发Windows 7 .NET Framework 3.5系统上可以正常工作。但是，如果我在Windows 2003 Server .NET 3.5 Framework上移动应用程序，结果将有所不同。有人能理解那里发生了什么吗？

I'm facing a problem about the conversion from string to decimal using C# .NET. The problem is that I have wrote the following code and works fine on my development Windows 7 .NET Framework 3.5 system. But, if I move the application on the Windows 2003 Server .NET 3.5 Framework the result is different. Can anyone understand what happen there?

代码：

dec = Convert.ToDecimal(strDec);

Windows 7结果：85.00
Windows 2003结果：8500

Windows 7 result: 85.00 Windows 2003 result: 8500

推荐答案

可能是服务器上的区域和区域性设置是用，设置为十进制，和。作为数字分组。请参阅控制面板/区域和区域性设置。

It may be that the region and culture settings on your server are set with , as decimal, and . as digit grouping. See Control Panel/region and culture settings.

如果此数字字符串是由您的应用程序生成的，则我将使用 CultureInfo.InvariantCulture

If this numeric string is generated by your application, I would use CultureInfo.InvariantCulture in both places.

     Decimal dec = 85.0m;
     string s = dec.ToString (CultureInfo.InvariantCulture);
     decimal.Parse(s, CultureInfo.InvariantCulture);
