如何解析具有多个小数点的字符串 [英] How to Parse a String with Multiple Decimal Points

问题描述

我想将一个字符串(例如"10.0.20")解析为一个数字，以便在C#.net中比较另一个具有相同格式的字符串

I was wanting to parse a string such as "10.0.20" into a number in order to compare another string with the same format in C#.net

例如，我将比较这两个数字以查看哪个小于另一个: 如果(10.0.30< 10.0.30)....

For example I would be comparing these two numbers to see which is lesser than the other: if (10.0.30 < 10.0.30) ....

我不确定应该为此使用哪种解析方法，因为在这种情况下，decimal.Parse(string)无法正常工作.

I am not sure which parsing method I should use for this, as decimal.Parse(string) didn't work in this case.

感谢您的时间.

@Romoku回答了我的问题，我不知道有一个Version类，这正是我所需要的.好吧，TIL.谢谢大家，如果不是您需要的话，我会花很多时间来研究表格.

@Romoku answered my question I never knew there was a Version class, it's exactly what I needed. Well TIL. Thanks everyone, I would have spent hours digging through forms if it wasn't for you lot.

推荐答案

您要解析的字符串看起来像是Verson，因此请尝试使用

The the string you're trying to parse looks like a verson, so try using the Version class.

var prevVersion = Version.Parse("10.0.20");
var currentVersion = Version.Parse("10.0.30");

var result = prevVersion < currentVersion;
Console.WriteLine(result); // true
