Hello all,

I have a question about how to use Include in linq. My SQL query is like:

SQL

Select * from tbl_Student where Student_ID include(select * from tbl_Exam)

Please anyone show me a way to use this in linq. I'm going to use Student DataTable and Exam DataTable then result to DataTable.

C#

DataTable result=dtStudent linq dtExam;

Thanks All,
