请问我这里代码是什么问题，运行起来就报错！
If RadioButton2.Checked Then
            Dim sql2 As String = "select * from [pc] where 电脑型号=" & rd2.Text
            Dim da2 As New OleDbDataAdapter(sql2, olecn)
            da2.Fill(ds, "[pc]")          （这里语法错误 (操作符丢失) 在查询表达式 '电脑型号=410MT2080-B' 中。）
            DataGridView1.DataSource = ds.Tables("[pc]").DefaultView
            da2.Dispose()

        End If

            Dim sql2 As String = "select * from [pc] where 电脑型号='" & rd2.Text & "'"
