Question

Hello, thanks for reading my question. I have a string that I need to put on a txt file.

I want to make it so that when the user clicks a button it asks for the folder, where the user wants to save this txt file, and generate it on in folder.

Here is some code I made but I do not know how to make it so that the user to chooses the folder.

private void Generar_Txt_Disco(string s_content, string s_folder)
{
        //Ruta es donde se va a guardar
        StreamWriter sr = new StreamWriter(s_folder);
        //Vas escribiendo el texto
        sr.WriteLine(s_content);
        //Lo cierras        
        sr.Close();           
}

Description

Use the SaveFileDialog or FolderBrowserDialog for that. (Member of System.Windows.Forms)

SaveFileDialog Prompts the user to select a location for saving a file. This class cannot be inherited.

FolderBrowserDialog Prompts the user to select a folder. This class cannot be inherited.

Sample for FolderBrowserDialog

private static void Generar_Txt_Disco(string s_content)
{
    using (FolderBrowserDialog dialog = new FolderBrowserDialog()) 
    {
        if (dialog.ShowDialog()) == DialogResult.OK)
        {
           //Ruta es donde se va a guardar
            StreamWriter sr = new StreamWriter(dialog.SelectedPath + "\\YourFileName.txt");
            //Vas escribiendo el texto
            sr.WriteLine(s_content);
            //Lo cierras        
            sr.Close();
        }
    }
}
