有没有更好的方式来替换字符串？

Is there a better way to replace strings?

我很惊讶，更换并不需要一个字符数组或字符串数​​组。我想，我可以写我自己的扩展，但我很好奇，如果有更好的内置的方法做到以下几点？请注意，最后更换是一个字符串不是字符。

I am surprised that Replace does not take in a character array or string array. I guess that I could write my own extension but I was curious if there is a better built in way to do the following? Notice the last Replace is a string not a character.

myString.Replace(';', 'n').Replace(',', 'n').Replace('r', 'n').Replace('t', 'n').Replace(' ', 'n').Replace("nn", "n");

感谢。

推荐答案

您可以使用替代常规EX pression。

You can use a replace regular expression.

s/[;,tr ]|[n]{2}/n/g

S / 开头意味着搜索 之间的字符 [和] 要搜索的字符（以任意顺序） 第二个 / 划定搜索文本和替换文本

s/ at the beginning means a search The characters between [ and ] are the characters to search for (in any order) The second / delimits the search-for text and the replace text

在英国，这个写着：

搜索; 或，或 t 或 r 或 （空间），或正好两个连续 ñ，并用替换ñ

"Search for ; or , or t or r or (space) or exactly two sequential n and replace it with n"

在C＃中，你可以做以下几点：（导入后 System.Text.RegularEx pressions ）

In C#, you could do the following: (after importing System.Text.RegularExpressions)

Regex pattern = new Regex("[;,tr ]|[n]{2}");
pattern.Replace(myString, "n");
