String.Replace not replacing apostrophe

Question

I'm trying to replace apostrophes with a string, for some reason the method just doesn't find the apostrophe in the string. Here is the URL that just doesn't seem to work:

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

Does anyone have any ideas?

Solution 1

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("’", "'");

Solution 2

The replace doesn't work because ’ and ' are not the same character.

And maybe you forgot to capture the result, your code is too short to tell.

Solution 3

’ and ' are different characters. You also need to assign it somewhere (strings are immutable), Replace() returns new string:

myString = myString.Replace("’", "'");

Solution 4

Since strings are immutable, you need to assign your result back to another string.

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

(note also that ` and ’ are not the same)

Solution 5

Your are replacing ' instead of ’. Also remember that strings are immutable, so you must assign the result to a new variable in case you want to store it.
