Question

This is probably a pretty simple LINQ question. I’m using LINQ to SQL and pulling a dataset.
My current code is this:

var tempTable = (from p in dc.Live_Diffs
                    where p.RowNum = 50
                    select new CustomResult
                    {
                        RowNum = p.RowNum,
                        ED1 = p.ED1,
                        ED2 = p.ED2,
                        ED3 = p.ED3,
                        ED4 = p.ED4,
                        ED5 = p.ED5,
                        ED6 = p.ED6,
                        ED7 = p.ED7,
                        ED8 = p.ED8
                    }).ToList();

How I can specify a where condition like the following: "where p.RowNum is in the set: {50,60,70}".
I have a list or doubles, and I am hoping to avoid using a large number of "OR" conditions…

Thanks a lot – kcross

Something like this should work for you:

var listOfConditions = new List<int>{50,60,70};
var tempTable = (from p in dc.Live_Diffs
                             where listOfConditions.Contains(p.RowNum)
                             select new CustomResult
                             {   RowNum = p.RowNum ,
                                 ED1 = p.ED1,
                                 ED2 = p.ED2,
                                 ED3 = p.ED3,
                                 ED4 = p.ED4,
                                 ED5 = p.ED5,
                                 ED6 = p.ED6,
                                 ED7 = p.ED7,
                                 ED8 = p.ED8
                             }).ToList();
