Invalid anonymous type member declarator. Anonymous type members must be declared with a member assignment, simple name or member access

Question

I\'m trying to add additional attribute data-icon to my Action Link, but I\'m getting the error below:

Invalid anonymous type member

Answer 1

Use "data_icon" instead of "data-icon".

        @Html.ActionLink("Profile", "Details", "Profile", new { id = 11 }, 
        new { @rel = "external", @id = "btnProfile", @data_icon = "gear" })

The _ will automatically be converted to - in the resulting markup.
