我一直在嘗試排除故障一段時間,我正式放棄。有人會幫我弄清楚下面的代碼有什麼問題。我正在上傳圖片,然後我想要顯示它。Asp.Net圖像不會顯示
這是我上傳的圖片中的代碼背後:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs)
If FileUpload1.HasFile Then
Try
FileUpload1.SaveAs("C:/BegASPNET/test/Pictures/Profile/" + FileUpload1.FileName)
Label1.Text = "File name: " + FileUpload1.PostedFile.FileName
Catch ex As Exception
Label1.Text = "ERROR: " & ex.Message.ToString()
End Try
Else
Label1.Text = "You have not specified a file."
End If
Using myEntities As New DatabaseEntities()
Dim pic As Picture
pic = New Picture()
pic.UserID = Profile.ID
pic.ImageUrl = "~/Pictures/Profile/" + FileUpload1.FileName
myEntities.AddToPictures(pic)
myEntities.SaveChanges()
End Using
End Sub
而且.aspx文件:
<asp:FileUpload ID="FileUpload1" runat="server" />
<asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click"/>
然後顯示圖像,我的代碼背後是:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Handles Me.Load
Using myProfile As New DatabaseEntities()
Dim prof = (From p In myProfile.UserProfiles
Where p.UserID = Profile.ID
Select p).SingleOrDefault()
dFNameLabel.Text = prof.FirstName
dLNameLabel.Text = prof.LastName
dDOBLabel.Text = prof.DOB
dGenderLabel.Text = prof.Gender
dEmailLabel.Text = prof.Email
Dim pic = (From pi In myProfile.Pictures
Where pi.UserID = Profile.ID AndAlso pi.picDefault = True
Select pi.ImageUrl).SingleOrDefault
End Using
End Sub
而我的.aspx文件是:
<asp:Image ID="ImageUrl" runat="server" ImageUrl='<%# Eval("ImageUrl") %>'/>
我確認圖像url位於數據庫中,並且圖像保存在文件中。如果我在.aspx文件的圖像控件中硬編碼絕對路徑,圖片將顯示。但是,它不會與上面的'<%#Eval(「ImageUrl」)%>'代碼一起使用。我不知道問題出在哪裏,所以任何幫助將不勝感激!
感謝穆罕默德!我嘗試了你的建議,但問題依然存在。 –
您在ImageURL中獲得了什麼? –
只有一個記錄在圖片表和ImageUrl列有〜/圖片/個人資料/姨媽Yolanda.jpg和picdefault列是:真 –
