如何檢索.mdf sql數據庫中的圖像在vb 2010

Question

我想檢索我保存到我的.mdf數據庫中的圖像。我需要這些代碼才能使我獲得數據並將其顯示在pictureBox中。

如何從.mdf數據庫中檢索圖像並在pictureBox的VB應用程序中顯示它們？

試試這個

Dim path As String = (Microsoft.VisualBasic.Left(Application.StartupPath, Len(Application.StartupPath) - 9)) 
Dim con As New SqlConnection("Data Source=[Server Name];AttachDbFilename=" & _ 
     path & "Database1.mdf;Integrated Security=True;User Instance=True") 
Dim cmd As SqlCommand 

cmd = New SqlCommand("select photo from Information where name='image1'", con) 
Dim imageData As Byte() = DirectCast(cmd.ExecuteScalar(), Byte()) 
If Not imageData Is Nothing Then 
    Using ms As New MemoryStream(imageData, 0, imageData.Length) 
     ms.Write(imageData, 0, imageData.Length) 
     PictureBox1.BackgroundImage = Image.FromStream(ms, True) 
    End Using 
End If
