XML encoding is necessary when we are saving XML text in an XML document. Basically there are five characters , that we need to deal with.

Escape CharacterXml Value
< &lt;
> &gt;
" &quot;
' &apos;
&&amp;


Here are diffrent ways you can encode XML in C#:

1. Use string.Replace() to replace the escape charters.


2. Use System.Web.HttpUtility.HtmlEncode() Used for encoding HTML, but HTML is a form of XML so we can use that too. Mostly used in ASP.NET apps. Note that HtmlEncode does NOT encode apostrophes ( ' ).

3. System.Security.SecurityElement.Escape() In Windows Forms or Console apps I use this method. If nothing else it saves me including the System.Web reference in my projects and it encodes all 5 chars.

4. System.Xml.XmlTextWriter Using XmlTextWriter is the safest way to create an xml document.
