Hi @Mandan_Purnima

According to your use case you can also use linq to solve this
Create a dt_final datatable

And use an assign statement

dt_final = (From f In dt_input.AsEnumerable()
 Join e In dt_EmployeeDetails.AsEnumerable()
 On f("EmpId").ToString() Equals e("EmpId").ToString()
 Select dt_final.LoadDataRow( New Object() {
               e("EmpId").ToString() & "_" & e("Department").ToString(),  
               f("EmpId"),                                               
               f("EmpName"),                                             
               e("JobTitle"),                                            
               f("Contact Number"),                                     
               e("Department"),                                        
               f("EmailAdress"),                                         
               e("HireDate"),                                           
               e("Salary")                                               
           },False)).CopyToDataTable()

Hope this helps!

Can you give me proper code for this if I want to add column dynamically like if column is not in other sheet so how to do dynamically

@Mandan_Purnima
Can you elaborate your use case based on what columns should added dynamically?
