C＃用单引号替换双引号

Question

I have a string that has two sets of double double quotes as below:

string ns = @"<tns:Event xmlns:tns=""http://sbr.gov.au/comn/event.02.data"">";

I need to replace the two sets of double double quotes around the namespace with a single quote but I'm struggling to see how to do it. I'm sure this is pretty easy but I'm pretty new to C#.

Thanks in advance.

Just to expand on my wider issue a little. Below is the code I'm using within an SSIS script component:

string xml = Row.RejectReason.ToString();
XDocument xDoc = XDocument.Parse(xml);
XNamespace tns = "http://sbr.gov.au/comn/event.02.data";
var eventItems = xDoc.Element(tns + "Event").Element(tns + "EventItems").Elements(tns + "EventItem");
foreach (var eventItem in eventItems)
{
   Row.RejectReason = eventItem.Element(tns + "Short.Description").Value;
}

The Parsing of the XML is failing due to the the double double quotes around the namespace within the XML. That XML fragment is coming from a CSV file.

Answer 1

when use @ before a string, you must type "" as ". At the end, ns contins

<tns:Event xmlns:tns="http://sbr.gov.au/comn/event.02.data">

or you can do this:

string ns = "<tns:Event xmlns:tns=\"http://sbr.gov.au/comn/event.02.data\">";

but no different

Answer 2

You can use string's Replace() method:

ns = ns.Replace('"', '\'');

or

ns = ns.Replace("\"", "'");

Answer 3

You can try a regex. Something like

var checkDoubleQuotes = @"""";
ns = Regex.Replace(ns, checkDoubleQuotes, "\"");

Answer 4

You can use an escape character for the quote. See this mdn article: Link

Answer 5

You can replace "" with \\' for single quote

 Regex.Replace(ns, @"""", "\'");

or replace "" with \\" for double quote

Regex.Replace(ns, @"""", "\"");
