我有一个字符串按以下格式

I have a string in the following format

string s = "This is a Test String.n   This is a next line.t This is a tab.n'

我想删除的所有出现ñ和 r 从上面的字符串。

I want to remove all the occurrences of n and r from the string above.

我已经试过字符串s = s.Trim（新的char [] {' N'，' r'}）; ，但它并没有帮助。

I have tried string s = s.Trim(new char[] {'n', 'r'}); but it didn't help.

推荐答案

我喜欢用普通的前pressions。在这种情况下，你可以这样做：

I like to use regular expressions. In this case you could do:

string replacement = Regex.Replace(s, @"t|n|r", "");

正前pressions不是在.NET世界最新流行的，因为他们是在动态语言，但它们提供大量的电力来操作字符串。

Regular expressions aren't as popular in the .NET world as they are in the dynamic languages, but they provide a lot of power to manipulate strings.
