Question

我的问题是，当我从OpenFileDialog上传我的图片时，个人资料图片不会更新。

我认为我的问题是我需要INotifyPropertyChanged，但我不知道如何使用我的代码。

这是我的代码：

private void ProfilUploadBillede_Click(object sender, RoutedEventArgs e)
    {
        OpenFileDialog op = new OpenFileDialog();
        op.Title = "Vælg dit profilbillede";
        op.Filter = "All supported graphics|*.jpg;*.jpeg;*.png|" +
          "JPEG (*.jpg;*.jpeg)|*.jpg;*.jpeg|" +
          "Portable Network Graphic (*.png)|*.png";
        if (op.ShowDialog() == true)
        {
            try
            {
                //Skriv data til SQL
                using (SqlConnection conn = new SqlConnection(@"Data Source=localhost\SQLEXPRESS;Database=fraekt;Trusted_Connection=True"))
                {
                    using (SqlCommand cmd = new SqlCommand())
                    {
                        cmd.CommandText = "UPDATE profil SET Billede='" + new Uri(op.FileName) + "' WHERE Email='" + Config.profil_email + "'";

                        cmd.Connection = conn;
                        conn.Open();
                        int rowsAffected = cmd.ExecuteNonQuery();
                    }
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show("A handled exception just occurred: " + ex.Message, "Exception Sample", MessageBoxButton.OK, MessageBoxImage.Warning);
            }
            finally
            {
                ProfilbilledeBig.Source = new BitmapImage(new Uri(op.FileName));
                profilbillede.Source = new BitmapImage(new Uri(op.FileName));
            }
        }
    }

这是我的XAML：

<Button x:Name="ProfilUploadBillede" Content="UPLOAD BILLEDE" HorizontalAlignment="Left" Height="37" Margin="187,391,0,0" VerticalAlignment="Top" Width="218" BorderBrush="#FFC11E2F" Background="#FFC11E2F" Foreground="White" FontSize="16" Cursor="Hand" Click="ProfilUploadBillede_Click"/>

修改编辑 我通过添加

来修复它

finally
            {
                ProfilbilledeBig.Source = new BitmapImage(new Uri(op.FileName));
                profilbillede.Source = new BitmapImage(new Uri(op.FileName));
            }

到我的代码：）

图像不会改变
