    </Grid>
</Window>

Also i have a class "User":

C#

class User
    {
        private String firstname;
        private String familyname;
        private String mystreet;
        private String myCity;
        private String myphone;
        private String myemail;
        private String myblog;

        public User()
        {


            firstname = ConfigurationManager.AppSettings.Get("firstname");
            familyname = ConfigurationManager.AppSettings.Get("familyname");
            mystreet = ConfigurationManager.AppSettings.Get("mystreet");
            myCity = ConfigurationManager.AppSettings.Get("mycity");
            myphone = ConfigurationManager.AppSettings.Get("myphone");
            myemail = ConfigurationManager.AppSettings.Get("myemail");
            myblog = ConfigurationManager.AppSettings.Get("myblog");

            DebugSettings();
            UserFile();
        }

        private void UserFile()
        {
            string[] lines = { "\\def\\firstname{" + firstname + "}", "\\def\\familyname{" + familyname + "}" , "\\def\\mystreet{" + mystreet + "}", "\\def\\mycity{" + myCity + "}", "\\def\\myphone{" + myphone + "}", "\\def\\myemail{" + myemail + "}", "\\def\\myblog{" + myblog + "}" };

            // Set a variable to the Documents path.
            string appDataPath =
              Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);

            // Write the string array to a new file named "WriteLines.txt".
            using (StreamWriter outputFile = new StreamWriter(Path.Combine(appDataPath, "personal_data.tex")))
            {
                foreach (string line in lines)
                    outputFile.WriteLine(line);
            }

        }

        private void DebugSettings()
        {
            string[] settings = { firstname, familyname, mystreet, myCity, myphone, myemail, myblog };

            foreach (string setting in settings)
                Console.WriteLine(setting);
        }

    }

In the MainWindow i use:

C#

private void btnGenerate_Click(object sender, EventArgs e)
        {
            User myuser = new User();
            
        }

In general i'm expecting after clicking on button "btnGenerate" that it runs the methods DebugSettings and UserFile.

But currently it looks like it doesn't outputs the settings nor it saves the file.

Have i missed anything?

What I have tried:

Also googled around, but nothing found :-(

You can check what happens when you riun it by using the debugger and stepping through the code. Note that a WPF application does not have a console, so none of those Console.WriteLine(setting); statements will do anything.

It's not enough to just put a method within your code, you have to tell WPF that you want to bind the button click in the XAML code as well. Take a look at this useful page[^] which explains how bind events to XAML controls.

You could also consider using a command[^] instead which would be bound to your view-model.

Solution 2

YOur btnGenerate_Clickmethod isn't hooked to the btnGenerate object in your XAML:

HTML

<Button x:Name="btnGenerate" Content="Generate" HorizontalAlignment="Left" Margin="549,384,0,0" VerticalAlignment="Top" Width="96"/>

You need to add Click = "btnGenerate_Click" to the XAML
