删除hexstring中的空格 [英] Remove whitespace in hexstring

问题描述

我有一个六弦，然后转换为字符串，但输出是+ 9 1 1 2 3 4 5 6 7 8 9



所以我想删除所有空格并获得仅限+91123456789的数字



我尝试过：

I have one hexastring then convert to string but output is + 9 1 1 2 3 4 5 6 7 8 9

so i want to remove all white space and get only number like [phone]

What I have tried:

string MobileNumber = "   + 9 1 1 2 3 4 5 6 7 8 9 ";
                            MobileNumber = Regex.Replace(MobileNumber, @"\s+", "");

推荐答案

这是来自：从.NET中的字符串中删除所有空格的最快方法 [ ^ ]

This is from: Fastest method to remove all whitespace from Strings in .NET[^]

static Regex whitespace = new Regex(@"\s+", RegexOptions.Compiled);

public static string TrimAllWithRegex(string str) {
    return whitespace.Replace(str, "");
}

正则表达式删除字符串有点过头了，不是吗？



为什么不只是

regex for String removal is a little bit over the top, isn't it?

why not just

number = number.Replace(" ","");

我想知道为什么你还有空格，解析HEX不应该......

I wonder why you have spaces anyway, parsed HEX shouldn't have ...
