Units of measure in C# - almost

Question

Inspired by Units of Measure in F#, and despite asserting (here) that you couldn\'t do it in C#, I had an idea the other day which I\'ve been playing around with.

Answer 1

Using separate classes for different units of the same measure (e.g., cm, mm, and ft for Length) seems kind of weird. Based on the .NET Framework's DateTime and TimeSpan classes, I would expect something like this:

Length  length       = Length.FromMillimeters(n1);
decimal lengthInFeet = length.Feet;
Length  length2      = length.AddFeet(n2);
Length  length3      = length + Length.FromMeters(n3);
