I need to Bind a list of my Available ports in Computer to a Combobox in WPF. I am using ObservableCollection. I have done like

public class MainWindowVM

    {

      public ObservableCollection<String> ListOfAvaliablePorts { get; set; }



        public MainWindowVM()

        {

            ListOfAvaliablePorts = new ObservableCollection<String>();

            ListOfAvaliablePorts.Add(SerialPort.GetPortNames());       

        }

    } 

But the output on the combobox Output is
String Array

My Xaml Code is

     <!--#region Combobox-->

            <ComboBox

                Name="portsCombobox" Width="80" Margin="50,0,0,0" 

                ItemsSource="{Binding ListOfAvaliablePorts}">

            </ComboBox>

            <!--#endregion-->

Please help me to solve the problem so that i can get the output like
COM1 COM2 COM6 COM7 COM5

initalize the ObservableCollection of string and give the list of ports.

public ObservableCollection<String> ListOfAvaliablePorts { get; set; }





 ListOfAvaliablePorts = new ObservableCollection<String>(SerialPort.GetPortNames());

If you want to bind a string array, then it just ObservableCollection . And you also need to implement INotifyPropertyChanged to raise the property change.

You can take a look as my solution as bellow:

public class MainWindowVM : INotifyPropertyChanged

{

    public event PropertyChangedEventHandler PropertyChanged;



    protected void OnPropertyChanged(string propertyName)

    {

        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));

    }



    private ObservableCollection<string> _ListOfAvaliablePorts;



    public ObservableCollection<string> ListOfAvaliablePorts

    {

        get

        {

            return _ListOfAvaliablePorts;

        }

        set

        {

            if (value != _ListOfAvaliablePorts)

            {

                _ListOfAvaliablePorts = value;

                OnPropertyChanged(nameof(ListOfAvaliablePorts));

            }

        }

    }



    public MainWindowVM()

    {

        var comPorts = SerialPort.GetPortNames();

        _ListOfAvaliablePorts = new ObservableCollection<string>(comPorts);

    }

}
