    Dim DD As New DataSet, State As New Statuez 
    Try 
     DD = R.Dset(Table, "Select **col()** from " & Table.TName & " where username='" & Table.User & "'") 
     DG.DataSource = DD.Tables(0)

***上校（）作爲字符串是一個數組保存列的名稱需要

有什麼辦法來選擇列陣列進行打字陣列的每個成員？

Answer 1

你可以這樣做：

Dim result As String = String.Join(",", Col)

然後在SELECT語句中使用result。

除此之外，也許你應該看看參數化你的語句，因爲它很容易被sql注入。
