从 DataTable 中读取数据 - ASP.NET

Question

我正在使用 ASP.net 4.5 和 VB.net。（C#例子也可以，我会转换）

我使用以下代码在我的表单上填充转发器控件。

Private pgdArticles As New PagedDataSource

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        pgdArticles = GetData()
        blogRepeater.DataSource = pgdArticles
        blogRepeater.DataBind()

    End Sub


    Private Function GetData() As PagedDataSource

        Dim pg As New PagedDataSource

        Dim conn As SqlConnection
        conn = New Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("myConnectionString").ConnectionString)

        Dim cmd As New SqlCommand("usp_MyProc", conn)

        Dim da As New SqlDataAdapter()
        da.SelectCommand = cmd
        Dim dt As New Data.DataTable()
        da.Fill(dt)
        pg.DataSource = dt.DefaultView

        Return pg

    End Function

使用中继器效果很好，但我想读取该数据并在我的表单上填充标签，而不是使用中继器。如下所示....

我的数据在我的 table.................

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        pgdArticles = GetData()

        If pgdArticles.ID = 1 Then
            lblName1 = pgdArticles.Name 'This will be value Mike
            lblValue1 = pgdArticles.Value 'This will be value 250
        End If

        If pgdArticles.ID = 2 Then
            lblName2 = pgdArticles.Name 'This will be value Ben
            lblValue2 = pgdArticles.Value 'This will be value 400
        End If

    End Sub

请问还有其他方法吗？ C# 或 VB.NET 代码示例都可以。

代码：

Public Property dtArticles As DataTable

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load

    dtArticles = GetData()

    For I As Integer = 0 To dtArticles.Rows.Count - 1
        Dim row As DataRow = dtArticles.Rows(I)
        Dim label As Label = Page.FindControl(String.Format("Name{0}", I))
        label.Text = String.Format("{0} ({1})", row("Name"), row("Value"))
    Next

End Sub

Private Function GetData() As DataTable

    Dim conn As New Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings("myConnectionString").ConnectionString)
    Dim cmd As New SqlCommand("usp_MyProc", conn)

    Dim da As New SqlDataAdapter()
    da.SelectCommand = cmd

    Dim dt As New Data.DataTable()
    da.Fill(dt)

    Return dt

End Function

Html:

<asp:Label ID="Name0" runat="server" />
<asp:Label ID="Name1" runat="server" />
<asp:Label ID="Name2" runat="server" />
