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.

The solution is to create an extension method with my own LabelFor method within:

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!
