Save stream of savefiledialog in c#

Question

In my wpf app I have an "Export" button that suppose to save some json file to chosen path.

I mean my question is how to write the file, let's say he has the path D:\somefile.json to the chosen location that the user chose from save dualog?

Here my code:

void Export_button_Click(object sender, RoutedEventArgs e)
{
        Stream myStream;
        SaveFileDialog saveFileDialog1 = new SaveFileDialog();
        saveFileDialog1.Filter = "Json files (*.json)|*.json";
        saveFileDialog1.FilterIndex = 2;
        saveFileDialog1.RestoreDirectory = true;

        if (saveFileDialog1.ShowDialog() == DialogResult.OK)
        {
            if ((myStream = saveFileDialog1.OpenFile()) != null)
            {
                // Code to write the stream goes here.
                myStream.Close();
            }
}

This should be something like:

Copy(StreamOf(D:\somefile.json),ChosenPath)

You can also do (assuming you serialized your json as string) File.WriteAllText(saveFileDialog1.FileName, jsonString); — mrvux, May 19 '18 at 20:36
`System.IO.File.Copy(@"D:\somefile.json", saveFileDialog1.FileName);` — JohnyL, May 19 '18 at 20:51

 SaveFileDialog sf = new SaveFileDialog();
 sf.Filter = "Json files (*.json)|*.json";
 sf.FilterIndex = 2;
 sf.RestoreDirectory = true;
 if (sf.ShowDialog() == DialogResult.OK)
 {                  
     System.IO.File.Copy(@"D:\somefile.json", sf.FileName, true);   
 }

you can use File.copy

public static void Copy(
string sourceFileName,
string destFileName)
