vb.net 中数据表的不同操作

Question

I have one DataTable with three columns "HOUSE_BILL_KEY","HOUSE_BILL_SRC_ID" and "SRC_RCRD_ID" and has data as shown

I want only distinct values from datatable like

how I will do it in behind the code?

Answer 1

It's probably better to do that in the SQL query that you're using to populate your dtCntnrHoubill table. Something like:

SELECT DISTINCT HOUSE_BILL_KEY, HOUSE_BILL_SRC_ID, SRC_RCRD_ID
FROM dtCntnrHoubill

But if you really want it in code behind, you can use LINQ:

Dim distinctResults = dtCntnrHoubill.Distinct()
