C# How to handle double quotes in string replace


How do I replace '\"' with '"' globally in C#
Backslash  Double Quotes replace with Double Quotes
and remove Double Quotes from the end of a string

string MyString = "Lorem \"ipsum\" dolor sit amet \"consectetuer\" ultrices turpis Phasellus et odio. Urna."";
MyString.Replace('\\"', '"'); // Error CS1012  C# Too many characters in character literal
MyString.Replace("\\"", "\""); didn't work

// Expected output
Lorem "ipsum" dolor sit amet "consectetuer" ultrices turpis Phasellus et odio. Urna.

While I see some inconsistencies in your code, I assume you want this:

fix string:
string MyString = "Lorem \"ipsum\" dolor sit amet \"consectetuer\" ultrices turpis Phasellus et odio. Urna.";

Open in new window

add on top:
using System.Text.RegularExpressions;

Open in new window

then use:
MyString = Regex.Replace(MyString, @"[\""]", "", RegexOptions.None); 

Open in new window

Because your expected output was already the original string. Now the output is without any quotes.
As I said, due to inconsistencies, I had to figure out what you want on my own. If that's not what you want, state it more clearly.

Thinking longer about it now, I think you want broken code to be fixed magically. That's not possible. If the code is already wrong on top, it won't compile, and the rest of the code is moot (including your paradoxal fixing code)

OK. Your opening line won't compile so that's wrong right from the start.

Secondly, if you Console.WriteLine() your string without doing any string replacement, you will get the correct results. The backslash simply escapes the quotes, so it won't be output.

Calling Replace on your string will currently do nothing as you're not assigning the return value to anything.

If you absolutely want to replace a \" with a ", then you need to escape both the slash and the quote. The escape character also happens to be the slash, so what you end up with is:

var newText = MyString.Replace("\\\"", "\"");

Maybe explain a little more about what you're trying to do and where your original text is coming from and we may be able to offer some more suitable advice.

Thank you the regex was what I needed

What I'm trying to do is clean up up some badly formed  HTML so I can parse it using HtmlAgilityPack;

Replacing the
was an obvious quick fix

The code I posted was only to try and illustrate the point

I used the regex  but can Chris solution also working
For some reason the whole HTML file / string was in Double Quote marks so I had to remove these from the first and last characters then remove the internal \ backslashes
