How to debug a LINQ Statement

Question

I have a Linq to objects statement

 var confirm = from l in lines.Lines 
 where (l.LineNumber == startline.LineNumber) || (l.LineNumber == endline.LineNumber         


        

Answer 1

While it isn't a way of debugging, I'd suggest using the following:

using (var db = new AppContext())
        {
            db.Database.Log = s => System.Diagnostics.Debug.WriteLine(s);
            // Rest of code
        }

You can then check the output window when debugging to see the SQL generated from your LINQ query.
