我正在尝试用字符串替换撇号，由于某种原因，该方法在字符串中找不到撇号。这是似乎不起作用的 URL：

"/news/2012/march/cameron’s-crackdown-on-whiplash-–-why-the-minimum-speed-requirement-is-oddly-suspicious"
.Replace("'", "'");

有没有人有任何想法？

由于字符串是不可变的，因此您需要将结果分配回另一个字符串。

string original = "/news/2012/march/cameron’s-crackdown-on-whiplash-–-why-the-minimum-speed-requirement-is-oddly-suspicious";
string updated = original.Replace("’","'");

（还要注意 ` 和 ' 是不一样的）

Strings are immutable types. You can't change them. Even if you think you change them, you create a new strings object. String.Replace() method also returns a new string by the way.

Try to assign in a new string reference with "’" not "'".

string str = "/news/2012/march/cameron’s-crackdown-on-whiplash-–-why-the-minimum-speed-requirement-is-oddly-suspicious".Replace("’", "'");

只需将结果分配给变量

var str = "...".Replace("'", "'");
