如何在double.ToString（）中更改小数点的符号？ [英] How to change symbol for decimal point in double.ToString()?

问题描述

我想在C＃中将小数点改为另一个字符。我有一个 double 变量值

  double value; 
  

当我使用命令：

  Console.WriteLine（value.ToString（））; //输出是1,25 
  

我知道我可以这样做：

  Console.WriteLine（value.ToString（
 CultureInfo.CreateSpecificCulture（en-GB）））; //输出是1.25 
  

但我不喜欢它，因为它很长，我需要在我的程序中经常出现。

是否有更短的版本设置小数点真的是点，而不是逗号，在我的文化中是平常的？

解决方案

一些快捷方式是创建一个NumberFormatInfo类，将其NumberDecimalSeparator属性设置为。并且只要你需要，就使用Class作为ToString（）方法的参数。

  NumberFormatInfo nfi = new NumberFormatInfo（）; 
 nfi.NumberDecimalSeparator =。; 
 
 value.ToString（nfi）; 
  

I would like to change decimal point to another character in C#. I have a double variable value

double value;

and when I use the command:

Console.WriteLine(value.ToString()); // output is 1,25

I know I can do this:

Console.WriteLine(value.ToString(
    CultureInfo.CreateSpecificCulture("en-GB"))); // output is 1.25

but I don't like it very much because it's very long and I need it quite often in my program.

Is there a shorter version for setting "decimal point" really as point and not comma as is in my culture is usual?

解决方案

Some shortcut is to create a NumberFormatInfo class, set its NumberDecimalSeparator property to "." and use the class as parameter to ToString() method whenever u need it.

NumberFormatInfo nfi = new NumberFormatInfo();
nfi.NumberDecimalSeparator = ".";

value.ToString(nfi);
