To dynamically write to app.config, pls look into Read/Write App.Config File with .NET 2.0[^]

I am assuming this is a Windows Application. To get and set Application Settings in this type of application you use

C#

Properties.Settings.Default.yourSettingName

. Thus for your example you would need to do something like this:

C#

private void btnAddTextBox_Click(object sender, EventArgs e)
        {
            //add dynamic textbox
            TextBox tb = new TextBox();
            tb.Top = btnAddTextBox.Top;
            tb.Left = btnAddTextBox.Left + btnAddTextBox.Width + 5;
            tb.Visible = true;
            tb.Name = "dynamicText";
            this.Controls.Add(tb);
        }
        private void btnSaveToSettings_Click(object sender, EventArgs e)
        {
            foreach (Control ctrl in this.Controls)
            {
                if (ctrl is TextBox)
                {
                    if (ctrl.Name == "dynamicText")
                    {
                        //save to settings
                        Properties.Settings.Default.dynamicText = ctrl.Text;
                    }
                }
            }
        }
        private void btnRetrieveFromSettings_Click(object sender, EventArgs e)
        {
            foreach (Control ctrl in this.Controls)
            {
                if (ctrl is TextBox)
                {
                    if (ctrl.Name == "dynamicText")
                    {
                        //set text to setting
                        ctrl.Text = Properties.Settings.Default.dynamicText;
                    }
                }
            }
        }

This assumes you have a setting in your app.config file called dynamicText

Hope this helps

Solution 4

Try this:
foreach (string key in ConfigurationManager.AppSettings)
{
//Get your key
string value = ConfigurationManager.AppSettings[key];
this.Url = value;
}
