推荐答案

引用：

它不显示图像

是抛出错误还是不显示图像？



无论如何，你应该在绑定中启用格式化。

Does it throw an error or does just not display the image?

In any case, you should enable formatting in the binding.

PictureBox1.DataBindings.Add("Image", dt, "photo", True)

i尝试使用您的解决方案，即使它无法正常工作。

最后我得到了一个解决方案就是，我为该控件添加了一个事件...

i tried with your solution, even it is not working.
finally i got one solution that is, i have added one event for that control as ...

Private Sub DataRepeater1_DrawItem(ByVal sender As System.Object, ByVal e As Microsoft.VisualBasic.PowerPacks.DataRepeaterItemEventArgs) Handles DataRepeater1.DrawItem
       Try
           Dim currItem As DataRowView = bs.Item(e.DataRepeaterItem.ItemIndex)
           If Not IsDBNull(currItem.Item("photo")) Then
               DirectCast(e.DataRepeaterItem.Controls("picturebox1"), PictureBox).Image = GetBitmap(DirectCast(currItem.Item("photo"), Byte()))
           Else
               DirectCast(e.DataRepeaterItem.Controls("picturebox1"), PictureBox).Image = Nothing
           End If
       Catch ex As Exception
           MsgBox(ex.Message.ToString)
       End Try
   End Sub

其工作效果e />
