asp.net - 在 asp.net 网站上开始打印 gridview1 的程序

Question

我有一个带有“作者”表的数据库“Pubs”。我通过拖动“作者”从数据库中创建了一个 dbml 文件。

这是“Default.aspx.vb”

Public Class _Default
    Inherits System.Web.UI.Page

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        Dim db As New PubsContext
        Dim products = From p In db.authors _
                       Select p

        GridView1.DataSource = author
        GridView1.DataBind()
    End Sub
End Class

这是它的类：“Class1.vb”

Partial Public Class PubsContext
    Public Function GetProductsByCategory(ByVal id1 As Integer) As IEnumerable(Of authors)
        Return From p In Me.authors _
               Where p.ProductID = id1 _
               Select p
    End Function
End Class

作者和作者的更正有一个红色下划线。我应该怎么办？
