Here is the code for my simple parsing application. I am getting an error that states 'No mapping exists from type System.Text.RegularExpressions.Match to a known managed provider native type'. This started to occur when I switched from using Split('_') to RegEx.Match for defining RNumberE, RNumberD, etc. Any guidance is appreciated.
