How to replace double quotes with / in a string with some other value in C#

Question

I have image tag in my html like img src="/images/image.jpg".

I want it like src="mydomain.com/images/image.jpg"

So I want to replace all src="/ to src="mydomain.com/. I tried this

                      string repto = "src=\"/" + strLink.HRef + "/";
                      strEncode.Replace("src=\"/", repto);

strEncode contains my html. I tried many ways but nothing is working. Please help, if any body has any idea about this. Thanks

_"I tried many ways"_ for instance? Also, what is this, ASP.NET, winforms(f.e. `WebBrowser`), javascript, HTML,...? Where and when do you want to modify them? — Tim Schmelter, Oct 01 '14 at 11:29
Have you tried [regex](http://stackoverflow.com/a/1732454/244935)? — Daniel Dinnyes, Oct 01 '14 at 11:31
By the way - it's not a very good idea to use absolute path in html code. — Andrey Korneyev, Oct 01 '14 at 11:31
a piece of could would be nice, otherwise you´ll get more and more down-votes. — MakePeaceGreatAgain, Oct 01 '14 at 11:41
Actually this html is coming from a feed and the path of image is relative. So i have to add domain name before the source to make it available. — user3815579, Oct 01 '14 at 11:48

Maybe

html_string.Replace("src=\"/images", "src=\"mydomain.com/images");

?

"not working". Aha. For my own I upvoted this as being a correct way. – C4d Oct 01 '14 at 11:40

Replace "html_string" with the name of your variable. Why not working? – i486 Oct 01 '14 at 11:43
I already replaced it, But not working I think It is not getting Escape character there. – user3815579 Oct 01 '14 at 11:50
"I think" is not enough. After replacing, why arnt you just echoing the string out to check how it looks like? I dont think the poster is responsible for every written character. – C4d Oct 01 '14 at 11:55

string foo = @"src=\"/images/image.jpg\"";
string bar = foo.Replace("src=\"", "src=\"mydomain.com");

String#Replace does not change the value of strEncode, in fact it returns a new string with the encoded value. So this may help you out:

strEncode = strEncode.Replace("src=\"/", repto);

An upvote or accept would be appreciated in this case – MakePeaceGreatAgain Oct 01 '14 at 13:32
