如何在Vb.net的数据库中以文件夹形式保存图像在Url形式中

问题描述

在我的项目中，我有PictureBox和用于在PictureBox中上传图像的浏览器按钮

所以如何保存文件夹中以及如何在数据库中保存图像路径我不能理解

我正在这样做，如下所示：

    Private Sub BtnUpdate_Click(sender As Object,e As EventArgs) Handles Button3.Click
            If con.State = ConnectionState.Open Then
                con.Close()
            End If
            con.open()
            cmd = con.CreateCommand()
            cmd.CommandType = CommandType.Text
            Dim fname As String
            Dim folder As String = "F:\Project In Asp.Net\VB.NET\Login\Login\Files"
            Dim pathString As String = System.IO.Path.Combine(folder,fname)
            Dim Id = Convert.ToString(combovehiclesmodel.SelectedValue)
            cmd.CommandText = "update Services set Servicesname = '" & txtservicesname.Text & "',Servicestypes='" & txtservicestype.Text & "',Fees='" & txtservicesfees.Text & "',damages='" & txtdamage.Text & "',Replace='" & txtreplace.Text & "',VehiclesId='" & Id & "',ServicesImage = @pathString = '" & PictureBox1.Text & "',where ServicesId=" & i & ""
            cmd.Parameters.AddWithValue("@pathString",pathString)
            cmd.ExecuteNonQuery()
    
            Dim a As Image = PictureBox1.Image
            a.Save(pathString)
            NotifyIcon1.ShowBalloonTip(1000,"Update","Update SuccessFull !!",ToolTipIcon.Info)
            disp_data()
            txtservicesname.Text = ""
            txtservicestype.Text = ""
            txtservicesfees.Text = ""
            txtdamage.Text = ""
            txtreplace.Text = ""
            combovehiclesmodel.Text = ""
        End Sub

还有我的浏览器按钮，它单击了事件

     Private Sub Btnbrowser_Click(sender As Object,e As EventArgs) Handles Btnbrowser.Click
            Dim op As OpenFileDialog = New OpenFileDialog
            op.Filter = "Image File (*.jpg;*.bmp;*.gif)|*.jpg;*.bmp;*.gif"
            If op.ShowDialog = DialogResult.OK Then
                PictureBox1.Image = Image.FromFile(op.FileName)
            End If
    
        End Sub
