C＃解析浮子字符串 [英] C# parsing float from string

问题描述

我从XML文件中读取数字。其他的数字是用逗号分隔符（0,1111）等人用点（0.1111）。我如何分析这些数字，所以我得到最终想要的结果？我试着用 float.Parse（reader.Value，System.Globalization.CultureInfo.InvariantCulture）; ，但它不工作。比如我有reader.Value =0,01119703，并解析为1119703.0。

I'm reading numbers from XML files. Other numbers are with a comma separator (0,1111) and others with dot (0.1111). How do I parse these numbers so I get the desired result in the end? I tried using float.Parse(reader.Value, System.Globalization.CultureInfo.InvariantCulture); but it doesn't work. For example I have reader.Value = "0,01119703" and is parsed as 1119703.0.

推荐答案

我不相信有可能在同一时间用两个不同的小数分隔工作。我想，我只想用替换（）来更改任何逗号进入点。

I don't believe that it is possible to work with two different decimal separators at the same time. I think I would just use Replace() to change any commas into dots.

float.Parse(reader.Value.Replace(',', '.'), System.Globalization.CultureInfo.InvariantCulture);
