I am working with a Umbraco site that has labels that look like this for required fields:

The problem is the standard @Html.LabelFor does not cater for this.

I had a look round the web and couldn’t find the exact code I wanted, as I really wanted to detect if the required data annotation attribute was set and only add the code if so.

You use it like this:

When browsing around the web, most of the examples I found were fairly trivial and didn’t cover the situation where I could detect the required attribute. The one problem I had with the above code is that if my requirements were more complex, using string.Replace didn’t feel like the correct method. I found this post that used the TagBuilder, which would solve this problem:

I have been working as a software developer since 1983. This blog could have been called "From Fortran 77, C and Cobol to C# in 20 (not so) easy years", but it doesn't sound quite right somehow. Besides I'm talking about what's happened since 2003, not before!
