How to replace straight quotation mark (")

Question

I would like to replace a straight quotation mark (") using C#.

I might be missing something small, but I can't get it with a normal string.Replace();

someWord.Replace(@""", "&");

Can I do it with a normal string.Replace(); or do I need to use Regex? If the latter, what would the Regex replace look like?

Solution 1

I agree with Heinzi, you should use " instead of &， and & means "&" Btw, after invoking the Replace method, don't forget to set the value to someWord again:

someWord = someWord.Replace("\"", """);

And there is another way to do it. Add the reference System.Web, and using System.Web; then:

someWord = HttpUtility.HtmlEncode（someWord);

Solution 2

someWord.Replace("\"", "&");

or

someWord.Replace(@"""", "&");

(Quotes are escaped as \" in regular strings and "" in verbatim strings.)

But you probably meant

someWord.Replace("\"", """);

since the HTML entity for straight quotation marks is ", not &.

Solution 3

someWord.Replace(@"""", "&");

or

someWord.Replace("\"", "&");

Will this replace all special characters? (HttpUtility.HtmlEncode（someWord);)

@Willem Yes,it will. If you just want to replace the straight quotation mark, don't use it.
