C# String.Replace not finding / replacing Symbol (™, ®)

Basically what I'm trying to do is replace a symbol like 开发者_如何转开发™, ® etc with something else but when I call

myString = myString.Replace("®", "something else")

Its doesn't do anything

Any Ideas?

try myString.Replace("\u00A9", "else"); you have to escape the ©

When you use String.Replace you create a new string. It is a very common mistake to believe the the supplied string is modified. However, strings in .NET are immutable and cannot be modified.

You have to call it like this:

myString = myString.Replace("®", "something else");

I assume that your mistake is in calling Replace without assigning the result to anything.

without seeing your code is difficult to guess, but something like this should work:

myString = myString.Replace("®", "something else");

It may be likely that C# does not like the literal registered symbol. I would suggest trying to replace the character by using a character code, using either the integral value, hex, or unicode.

Below is an example using the integral value of the character ®.

string originalString = "whatever®";
string stuff = "something else";
char registered = (char)174;
string replacedString = originalString.Replace(registered, stuff);

Remember that string.Replace returns a new string, so you need to re-assign it

myString = myString.Replace("®", "something else");

Try to use Unicode characters to replace this symbols.

        string x = "® ™ dwdd2";
        string y = x.Replace('\u00AE', 'X');

It's working ;-)

And a list of Charakters:

It works for me:

var myString = "Hello world ®, will this work?";
var result = myString.Replace("®", "something else");
Console.WriteLine(result);

results in:

Hello world something else, will this work?

You can see it run here.

Does your original string really contain that character or does it contain something like an html entity: ® or ® or other "encoded" version of that character?
