Strip double quotes from a string in .NET

Question

I'm trying to match on some inconsistently formatted HTML and need to strip out some double quotes.

Current:

<input type="hidden">

The Goal:

<input type=hidden>

This is wrong because I'm not escaping it properly:

s = s.Replace(""","");

This is wrong because there is not blank character character (to my knowledge):

s = s.Replace('"', '');

What is syntax / escape character combination for replacing double quotes with an empty string?

Answer 1

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

You need to use the \ to escape the double quote character in a string.

Answer 2

You have to escape the double quote with a backslash.

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

Answer 3

I think your first line would actually work but I think you need four quotation marks for a string containing a single one (in VB at least):

s = s.Replace("""", "")

for C# you'd have to escape the quotation mark using a backslash:

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

Answer 4

s = s.Replace("\"",string.Empty);

Answer 5

You can use either of these:

s = s.Replace(@"""","");
s = s.Replace("\"","");

...but I do get curious as to why you would want to do that? I thought it was good practice to keep attribute values quoted?

Answer 6

c#: "\"", thus s.Replace("\"", "")

vb/vbs/vb.net: "" thus s.Replace("""", "")

Answer 7

s = s.Replace( """", "" )

Two quotes next to each other will function as the intended " character when inside a string.

Answer 8

s = s.Replace(@"""", "");
