Ajaxfileupload上传只有一张图片

Question

大家好我已创建了一个AJAX文件上传，但它仅导入的第一张照片到我的数据库u能帮助解决这个问题，请与Response.Redirect的是不是工作压力太大

Dim sellerid1 As Integer 
    Using con1 As New SqlConnection(_start) 
     Dim conss1 As New SqlConnection(_start) 
     Dim sql2 As String = "SELECT SellerID FROM Seller INNER JOIN Member ON Seller.MemberID = Member.MemberID WHERE(Member.Username = @username)" 
     Dim mycommand As New SqlCommand(sql2, conss1) 
     conss1.Open() 
     mycommand.Parameters.AddWithValue("@username", Session("user")) 
     sellerid1 = Convert.ToInt32(mycommand.ExecuteScalar) 
    End Using 

    Dim filename As String = e.FileName 
    Dim strDestPath As String = Server.MapPath("~/Seller/images/") 
    AjaxFileUpload1.SaveAs(strDestPath & filename) 

    Dim Imagepath As String = "~/Seller/images/" & filename 
    Dim conss As New SqlConnection(_start) 
    conss.Open() 
    Dim sql1 As String = "SELECT TOP (1) ItemID FROM Item WHERE (SellerID = @sellerid) ORDER BY ItemID DESC" 
    Dim mycommand2 As New SqlCommand(sql1, conss) 
    mycommand2.Parameters.AddWithValue("@sellerid", sellerid1) 
    ItemID = mycommand2.ExecuteScalar 

    Dim sql As String = "INSERT INTO Image(Image,ItemID) VALUES (@image,@item)" 
    Dim myCommand1 = New SqlCommand(sql, conss) 

    myCommand1.Parameters.AddWithValue("@image", Imagepath) 
    myCommand1.Parameters.AddWithValue("@item", ItemID) 
    myCommand1.ExecuteNonQuery() 
    Response.Redirect("Views/Default2.aspx")

尝试使用UploadComplete和UploadCompleteEvent

象下面这样：

Protected Sub FileUpload_UploadComplete(sender As Object, e As AjaxControlToolkit.AjaxFileUploadEventArgs) Handles FileUpload.UploadComplete 

    Using con1 As New SqlConnection(_start) 
    Dim conss1 As New SqlConnection(_start) 
    Dim sql2 As String = "SELECT SellerID FROM Seller INNER JOIN Member ON Seller.MemberID = Member.MemberID WHERE(Member.Username = @username)" 
    Dim mycommand As New SqlCommand(sql2, conss1) 
    conss1.Open() 
    mycommand.Parameters.AddWithValue("@username", Session("user")) 
    sellerid1 = Convert.ToInt32(mycommand.ExecuteScalar) 
    End Using 

    Dim filename As String = e.FileName 
    Dim strDestPath As String = Server.MapPath("~/Seller/images/") 
    AjaxFileUpload1.SaveAs(strDestPath & filename) 

    Dim Imagepath As String = "~/Seller/images/" & filename 
    Dim conss As New SqlConnection(_start) 
    conss.Open() 
    Dim sql1 As String = "SELECT TOP (1) ItemID FROM Item WHERE (SellerID = @sellerid) ORDER BY ItemID DESC" 
    Dim mycommand2 As New SqlCommand(sql1, conss) 
    mycommand2.Parameters.AddWithValue("@sellerid", sellerid1) 
    ItemID = mycommand2.ExecuteScalar 

    Dim sql As String = "INSERT INTO Image(Image,ItemID) VALUES (@image,@item)" 
    Dim myCommand1 = New SqlCommand(sql, conss) 

    myCommand1.Parameters.AddWithValue("@image", Imagepath) 
    myCommand1.Parameters.AddWithValue("@item", ItemID) 
    myCommand1.ExecuteNonQuery() 
End Sub 

Protected Sub FileUpload_UploadCompleteAll(sender As Object, e As AjaxControlToolkit.AjaxFileUploadEventArgs) Handles FileUpload.UploadCompleteAll 
    Response.Redirect("Views/Default2.aspx",False) 
End Sub
