XAttribute.SetValue converts "

Question

In my application I'm using XAttribute.SetValue(...) to set the value of an xml-attribute. The value is provided by the user.

I have the following methode to set the attribute-value:

private void SetValue(XAttribute attribute, string input)
{
    attribute.SetValue(input);
}

If the input is Hello "World" then the value of the attribute is: Hello "World"

This is what I've expected.

If the input is already "masked" like Hello "World" then the value of the attribute is: Hello &quot;World&quot;

That's not correct.

Is there a way to avoid this conversion?

You should of removed the double quotes from input before call the method. You can remove the double quotes simply by using replace : input = input.Replace("\"", ""); — jdweng, Aug 19 '19 at 09:56
I don't think you can avoid it, but you can make sure the input is not already encoded with something like `System.Net.WebUtility.HtmlDecode(input)` before you call `SetValue` — steve16351, Aug 19 '19 at 10:08
Thanks. `System.Net.WebUtility.HtmlDecode(input)` solved the problem. Post it as answer, so I can accept it — Tomtom, Aug 19 '19 at 12:03

You can not stop SetValue encoding characters such as & to entity codes. So, to avoid them being double encoded, you can make sure your input is not encoded to start with. You can do this using:

System.Net.WebUtility.HtmlDocode(input)

Or, if you have a reference to System.Web already,

System.Web.HttpUtility.HtmlDecode(input)

XAttribute.SetValue converts "
