vb.net – 使用SQLDataReader而不是recordset

我是新手,有这个问题.我可以使用sqlDataReader而不是Recordset.我想在sqlDataReader中实现以下结果.

Dim dbConn As New ADODB.Connection
Dim rs As New ADODB.Recordset
Dim sqlstr As String = "SELECT Name,Status FROM table1 WHERE id=" + item_id.Value.ToString
rs.Open(sql,dbConn)
While Not rs.EOF
   txtName.Text = rs.Fields.Item("Name").Value
   ddlstatus.Selectedindex = 1
   rs.MoveNext()
End While
rs.Close()
rs = nothing
dbConn.Close()
dbConn = nothing

我可以用sqlDataReader替换记录集吗？如果可以,请告诉我代码中的更改？

强烈建议您使用使用模式：

Dim sConnection As String = "server=(local);uid=sa;pwd=PassWord;database=DatabaseName"
    Using Con As New sqlConnection(sConnection)
        Con.open()
        Using Com As New sqlCommand("Select * From tablename",Con)
            Using RDR = Com.ExecuteReader()
                If RDR.HasRows Then
                    do while RDR.Read
                        txtName.Text = RDR.Item("Name").ToString()
                    Loop
                End If
            End Using
        End Using
        Con.Close()
    End Using
