圖像顯示

Question

我不能在我的aspx視圖中顯示的圖像.. 我使用的MySQL數據庫

我有我的模型驗證碼：

Imports Microsoft.VisualBasic 
Imports System.Data 

Public Class ClassPhotosConnection 
    Inherits ClassConnection 

    Public Function pictureSelect() As DataTable 
     Return ReadData("SELECT * FROM pictures") 
    End Function 
End Class 

用於控制器：

Public Class AdministrationController 
    Inherits Global.System.Web.Mvc.Controller 
    Private dPhotos As New ClassPhotosConnection 

     <AcceptVerbs(HttpVerbs.Get)> _ 
     Function Photos() As ActionResult 
      Dim _photos As DataTable = dPhotos.pictureSelect() 
      Return View(_photos) 
     End Function 
End Class 

爲視圖：

<div> 
    <form action="<%url.action("Photos") %>"> 
    <%Using Html.BeginForm%> 
    <%Dim _photos As datatable = ViewData.Model%> 
    <%For count As Integer = 0 To _photos.Rows.Count - 1%> 
    <img src='<%=_photos.Rows(count).Item("picURL") %>' alt="" /> 
    <p> 
    <%=_photos.Rows(count).Item("picCaption")%> 
    </p> 
    <%Next%> 
    <%End Using%> 
    </form> 
</div> 

唯一顯示的是picCaption ..它似乎不能調用src ='<％= _ photos.Rows（count）.Item（「picURL」）％>' 我怎麼能顯示圖像？

謝謝！

Answer 1

picURL是否包含對圖像的相對或絕對引用？如果引用是真實的，那麼您可能需要使用Url.Content方法來正確映射路徑。

<img src='<%= Url.Content("~/" + _photos.Rows(count).Item("picURL")) %>' alt="" />
