c# - How to get what's in datatable where exist in another datatable by LINQ -

-

if have 2 datatables :

dt1  emp_num name  status      1    aa    1      2    bb    1      3    cc    2  
dt2   emp_num name  dep_code   1      aa       536   2      bb       782   4      yuw      21   5      rr       892

how in dt1 , must exist in dt2 , put result in datatable

the result :

emp_num name  status   1      aa    1   2      bb    1

you use linq

var result = (from in dt1.rows              join b in dt2.rows              on dt1.rows["emp_num"]==dt2.rows["emp_num"]              select a).copytodatatable<datarow>();
