Question

我正在尝试编写使用用户输入来查询数据库然后在VB 2015中显示GridView的代码。我收到编译错误，无法弄清楚我做错了什么。

这是我的所有.VB编码。为了测试目的，我故意将变量设置为已定义的数字。

Imports System.Data
Imports System.Data.SqlClient

Partial Class BeaversInc_GridTest
    Inherits System.Web.UI.Page

    Dim strConnectionString As String

    Public Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
        If Not IsPostBack Then
            Dim conn As New SqlConnection(strConnectionString)
            Dim drDataReader As SqlDataReader
            Dim dtDataTable As New DataTable
            Dim cmd As New SqlCommand

            Dim intStoreNumber As Integer
            Dim dteStartDate As Date
            Dim dteEndDate As Date

            intStoreNumber = "686"
            dteStartDate = CDate("11/15/2013")
            dteEndDate = CDate("11/15/2015")

            conn.ConnectionString = ConfigurationManager.ConnectionStrings("ConnectionString1").ConnectionString
            cmd.Connection = conn
            cmd.CommandType = Data.CommandType.StoredProcedure
            cmd.CommandText = "CriticalFails"

            With cmd.Parameters
                .AddWithValue("@StoreNumber", intStoreNumber)
                .AddWithValue("@StartDate", dteStartDate)
                .AddWithValue("@Enddate", dteEndDate)
            End With

            conn.Open()
            drDataReader = SqlCommand.ExecuteReader
            dtDataTable.Load(drDataReader)
            GridView1.DataSource = dtDataTable
            GridView1.DataBind()
            conn.Close()
        End If
    End Sub
End Class

第＆＃34; drDataReader = SqlCommand.ExecuteReader＆＃34;不应该是＆＃34; drDataReader = cmd.ExecuteReader＆＃34; ??
