In C#, how can I decode HTML characters?


Email addresses have been encoded using HTML character entities. Is there a way to convert them to simple strings in.NET?

HttpUtility.HtmlDecode can be used.

You can also use WebUtility if you’re using.NET 4.0 or higher. HtmlDecode, which is present in the System and does not require an additional assembly reference. The namespace of the internet.

You should use HttpUtility, as @CQ suggested. HtmlDecode is a useful tool, but it’s not included by default in non-ASP.NET projects.

A reference to System.Web.dll is required for non-ASP.NET applications. In Solution Explorer, right-click your project and choose “Add Reference,” then look for System.Web.dll in the list.

You should be able to access the method using the fully-qualified name System.Web.HttpUtility.HtmlDecode now that the reference has been added, or you can use a using statement for System.Web to make things easier.

You can use HttpUtility if there is no Server context (i.e. you’re offline). HtmlDecode.

It’s also worth noting that, like me, if you’re using HtmlAgilityPack, you should keep using HtmlAgilityPack. HtmlEntity. DeEntitize(). It accepts a string and outputs another string.
