IQueryable to LINQ C# syntax formatter

2 minute read Published:

Technically, the title of this article should be System.Linq.Expressions.Expression to LINQ C# syntax formatter but that’s a bit lengthy. To get right to the point, I’ve developed a class to parse an Expression tree generated by a LINQ IQueryable query and produce C# LINQ syntax as output. I tried searching the internet for similar work and nothing was immediately available or that was in source form for me to integrate with my tool. So, I wrote my own. Here’s some sample output from the class:

// C# LINQ query:
var query =
     from x in (
          from ea in TableA
          join et in TableB on ea.TableBID equals et.TableBID
          join es in TableC on ea.TableCID equals es.TableCID
          join st in TableD on ea.TableDID equals (int?)st.TableDID
          join sf in TableE on ea.TableEID equals (int?)sf.TableEID
          join eb in TableF on ea.TableFID equals eb.TableFID
          join psf in TableF on ea.PreviousTableFID equals (int?)psf.TableFID into temp from ps in temp.DefaultIfEmpty()
          select new { ea = ea, et = et, es = es, st = st, sf = sf, eb = eb, ps = ps }
     where ((x.ea.DueDate < (DateTime?)DateTime.Now.Date) && ( != "C"))
     select x
     .OrderBy(a => a.ea.DueDate)

This class is intended primarily for display purposes. It should not be used in its current state for attempting to write out compilable C# LINQ syntax. Download the code:
