I'm been wondering is there a way to save a file in specific's folder in C#?

The only method that I know is 'SaveFileDialog' but the problems is I want to save files

in folder without showing saveFilesDialog's Box.

saveFilesDialog's Box : is a box that prompts you to Click 'YES' or 'CANCEL'.

Code samples

-In form1

public Form1()
 {
   InitializeComponent();
 }

private string Path =@"D:\Files";  //locaction i wanna stores all the files in
private int i = 0;
private button1_Click(object sender,EventArgs e) 
{
    i  ;
    SaveDialogFile save = new SaveDialogFile();
    if(Save.

    if (save.ShowDialog() != DialogResult.OK)return; //Prompt's Dialog will show


    save.Filter = "File Text(*.txt)|*.txt";
    save.InitialDirectory = Path;
    save.FileName = "txt" i.ToString();

    //Goal : i want 'save.FileName' store in 'Path' without Click 'OK' or Show Prompt Dialog's box

    
}

Anyone can help me? I kinda stuck rn :)

This is my full code it's hard to read but you'll get the point

public partial class convertMp3ToWav : Form
    {
        public convertMp3ToWav()
        {
            InitializeComponent();
        }
        BackgroundWorker bw;
        string withoutEx;
        List<string> song_lists = new List<string>();

        private void button1_Click(object sender, EventArgs e)
        {
            bw = new BackgroundWorker();
            bw.DoWork  = (obj, ae) => newThread();
            bw.RunWorkerAsync();
        }
        void newThread()
        {

            Thread th = new Thread
            ((ThreadStart)(() =>
            {
                file();
            }));
            th.SetApartmentState(ApartmentState.STA);
            th.Start();
            th.Join();
        }
        void file()
        {
            
            string path = @"D:\musics\wav";
            Directory.CreateDirectory(path);
            FolderBrowserDialog f = new FolderBrowserDialog();
            f.ShowDialog();
            string[] lists = Directory.GetFiles(f.SelectedPath, "*.*", SearchOption.AllDirectories);
            foreach (string list in lists)
            {
                if (Path.GetExtension(list) == ".mp3")
                {
                    string fn = Path.GetFullPath(list);
                    withoutEx = Path.GetFileNameWithoutExtension(fn);
                    song_lists.Add(fn);
                    Console.WriteLine(withoutEx);

                    SaveFileDialog save = new SaveFileDialog();
                    save.Filter = "Wav FIle (*.wav)|*.wav;";
                    //save.FileName = song_lists[0];
                    save.FileName = withoutEx;
                    save.InitialDirectory = path;


                    if (save.ShowDialog() == DialogResult.OK)
                    {
                        using (Mp3FileReader mp3 = new Mp3FileReader(fn))
                        {
                            using (WaveStream pcm = WaveFormatConversionStream.CreatePcmStream(mp3))
                            {
                                WaveFileWriter.CreateWaveFile(save.FileName, pcm);
                            }

                        }
                    }
                    
                }

            }
           
            
        }

     
    }

this code's work pretty well!! but i need to click 'OK' everytime!! so is there anyway to save file without click 'OK' everytime!!

CodePudding user response：

Conceptually the only thing SaveFileDialog is doing, if you merely click OK when it shows, is changing the file extension*. Use Path.ChangeExtension instead

var pathToSaveWavTo = Path.ChangeExtension(pathToMp3, "wav");

The wav will be saved alongside the mp3. If you want to save it elsewhere, use Path.Combine to build a new path e.g.

pathToSaveWavTo = Path.Combine(@"c:\temp", Path.GetFileName(pathToSaveWavTo));

*_{I say this because giving it a filter of *.WAV and a filename xxx without the mp3 extension will cause it to give you a filename of xxx.wav when you only click OK, thus xxx.mp3 -> xxx.wav}
