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

It is possible to step inside the LINQ expression without setting any temporary breakpoints. You need to step into the function which evaluates the LINQ expression, e.g.:

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

 confirm.ToArray(); // Press F11 ("Step into") when you reach this statement

 foreach(var o in q) // Press F11 when "in" keyword is highlighted as "next statement"
    // ...
