Change the search options.

I have file which searches through different directories. The file code is hard coded to to return only mp3 files. I'm trying to edit it so that the user can select which file extensions such mp3 or txt ect.

I tried using a check-box with no effect.

private void btnOpenFolder_Click(object sender, System.EventArgs e)
        {
            this.folderBrowserDialog.RootFolder = System.Environment.SpecialFolder.MyComputer;
            this.folderBrowserDialog.ShowNewFolderButton = false;
            DialogResult result = this.folderBrowserDialog.ShowDialog();
            if (result == DialogResult.OK)
            {
                this.clearListBox();

                // retrieve the name of the selected folder
                string foldername = this.folderBrowserDialog.SelectedPath;

                // print the folder name on a label
                this.textSearchPath.Text = foldername;

                

                foreach (string filename in Directory.GetFiles(foldername))
                {
                    string FileTypeExtension = ".mp3";
                    string extension = Path.GetExtension(filename);

                    if (extension == FileTypeExtension)
                    {
                        this.listBox1.Items.Add(filename);
                    }
                }
            }

            
        }


        private void clearListBox()
        {
            this.listBox1.Items.Clear();
        }

        private void Close_Click(object sender, EventArgs e)
        {
            this.Close();
        }

        private void checkBox1_CheckedChanged(object sender, EventArgs e)
        {
            string FileTypeExtension = ".txt";
        }

        private void MP3File_CheckedChanged(object sender, EventArgs e)
        {
            string FileTypeExtension = ".mp3";
        }

        private void Clear_Click(object sender, EventArgs e)
        {
            this.listBox1.Items.Clear();
        }

        private void ShowFiles_Click(object sender, EventArgs e)
        {
           
        }


    }
}

So the User gets to choose 2 things..

1) The Folder
2) The Extension

And then you want to get a list of all of the files in the folder (1) with the extension (2).

Can you confirm?

Looks to me like you need to make FileTypeExtension global to the class (only declare it once).

[vcdebugger]

yes.. Energ1ser is right. string FileTypeExtension needs to be declared only once outside the class and FileTypeExtension to be used where ever it is required.

[rliq]

He is right, although I think the compiler would generate the same code in this case... but then...
