C＃联接2个不带LINQ的数据表

Question

I want to join two data tables using C# without using LINQ. How can I do it?

Answer 1

Are you trying to concatenate two datatables to a new one? If so, do this

DataTable result= table1.Copy();
result.Merge(table2);

where table1 and table2 are DataTables

Answer 2

use a single statment that joins the tables in SQL, ie

select * from table1 t1, table2, t2 where t1.id = t2.id
