How to create dataset:-

DataSet dsCustomer= new DataSet();

1,480,000 results on create dataset in ado.net

Create Two DataTables:-

DataTable customersMast = dsCustomer.Tables.Add("CustomersMaster");
DataTable customersDet = dsCustomer.Tables.Add("CustomersDetails");

1,030,000 results on create datatable in ado.net

Relationship between two datatables:-

ForeignKeyConstraint custOrderFK = new ForeignKeyConstraint("CustOrderFK",
custDS.Tables["CustTable"].Columns["CustomerID"], 
custDS.Tables["OrdersTable"].Columns["CustomerID"]);
custOrderFK.DeleteRule = Rule.None;  
// Cannot delete a customer value that has associated existing orders.
custDS.Tables["OrdersTable"].Constraints.Add(custOrderFK);

Please don't forget to mark this as your answer if it helps you out.

Thanks
