This article will tell you how to use OpenFileDialog using WPF. OpenFileDialog represents a common dialog box that displays the control that allows the user to open a file. This class cannot be inherited.

First of all make a new WPF application and go to .xaml window.

<Grid>
        <Button Content="Browse" Height="32" HorizontalAlignment="Left"
                Margin="20,12,0,0" Click="button1_Click"
                Name="button1" VerticalAlignment="Top" Width
="136" />
        <Image Margin="12,70,0,20" Name="MyImage" Stretch="Fill" HorizontalAlignment="Left" Width="200" />
        <ListBox Margin="263,70,46,20" Name="listBox1" />
    </Grid>

.xaml.cs

private void button1_Click(object sender, RoutedEventArgs e)
        {
            Stream checkStream = null;
            Microsoft.Win32.OpenFileDialog openFileDialog = new Microsoft.Win32.OpenFileDialog();

            openFileDialog.Multiselect = false;
            //
openFileDialog.InitialDirectory = "c:\\";
            //if you want filter only .txt file
            //dlg.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";

            //if you want filter all files           
            openFileDialog.Filter = "All Image Files | *.*";

            if ((bool)openFileDialog.ShowDialog())
            {
               
try
                {
                    if ((checkStream = openFileDialog.OpenFile()) != null)
                    { 
                       MyImage.Source = new BitmapImage(new Uri(openFileDialog.FileName, UriKind.Absolute));
                        listBox1.Items.Add(openFileDialog.FileName);
                        MessageBox.Show("Successfully done");
                    }
                }
                 catch (Exception ex)
                {
                        MessageBox.Show("Error: Could not read file from disk. Original error: " + ex.Message);
                }

            }
           
else
            {

                MessageBox.Show("Problem occured, try again later");

             }
        }

Now run application. You will see result like this.
