c# - How to modify this Select Statement inorder to get the data using LINQ? -


i have 2 data tables lsstitable , lsstitable1. want fetch data row1 , row2 satisfying conditions.i think error because row1 , row2 after satisfying condition row1 returns 3 things ldsid,looppairid, loccode. loccode returns null value. hence error. how overcome that?

var rowdata =  (from row1 in lsstitable.asenumerable()   join row2 in lsstitable1.asenumerable()   on new { = row1.field<int>("ldsid"), b = row1.field<byte>("looppairid") }   equals new { = row2.field<int>("ldsid"), b = row2.field<byte>("looppairid") }   select new { row1, row2 }).tolist();

this error get

'system.data.datarow' not contain definition 'loccode' , no extension method 'loccode' accepting first argument of type 'system.data.datarow' found (are missing using directive or assembly reference?)

recheck whether ldsid , looppairid int , byte in database tables..it other type.
