WPF  mit C♯ 

Vorbereitung

Für die WPF -Programmierung müssen einige zusätzliche Bibliotheken referenziert werden.

»[global::System.STAThread]«

Das Attribut »[global::System.STAThread]« muß der Hauptmethode von Programmen, die WPF  verwenden, gegeben werden. Es ist zur WPF -Programmierung nicht nötig, die genaue Bedeutung dieses Attributes zu kennen.

Program.cs

public static class Program
{ [global::System.STAThread] public static void Main()
  {  }}

»System.Windows.Application«

Die Klasse des Programmes muß die Klasse »System.Windows.Application« erweitern. Dazu darf sie nicht mehr »static« sein.

Program.cs

public class Program : global::System.Windows.Application
{ [global::System.STAThread] public static void Main()
  {  }}

»System.Windows.Window«

Das folgende Programm zeigt ein neues Fenster an. Da das Programm aber unmittelbar danach endet, wird das Fenster auch sofort wieder geschlossen.

Program.cs

public class Program : global::System.Windows.Application
{ [global::System.STAThread] public static void Main()
  { global::System.Windows.Window window = new System.Windows.Window();
    window.Show(); }}

»new global::System.Windows.Application().Run()«

Durch den Aufruf der Run-Methode wird ein Ereigniswächter gestartet, der auf eventuelle Eingaben in dem Fenster reagieren kann. Solange dieser läuft bleibt auch das Fenster sichtbar.

Program.cs

public class Program : global::System.Windows.Application
{ [global::System.STAThread] public static void Main()
  { global::System.Windows.Window window = new System.Windows.Window();
    window.Show(); 
    new global::System.Windows.Application().Run(); }}

Program.cs

public class Program : global::System.Windows.Application
{ [global::System.STAThread] public static void Main()
  { global::System.Windows.Window window = new global::System.Windows.Window();
    window.Title = "Programmbeispiel";
    window.Show(); 
    new global::System.Windows.Application().Run(); }}

Program.cs

public class Program : global::System.Windows.Application
{ [global::System.STAThread] public static void Main()
  { var window = new global::System.Windows.Window();
    window.Title = "Programmbeispiel";
    var textBox = new global::System.Windows.Controls.TextBox();
    window.Content = textBox;
    window.Show(); 
    new global::System.Windows.Application().Run(); }}

Program.cs

public class Program : global::System.Windows.Application
{ static readonly global::System.Windows.Controls.TextBox textBox 
  = new global::System.Windows.Controls.TextBox();
  [global::System.STAThread] public static void Main()
  { var window = new global::System.Windows.Window();
    window.Title = "Programmbeispiel";
    textBox.FontSize *= 4;
    textBox.TextInput += /* Strg-Eingabe */
    new global::System.Windows.Input.TextCompositionEventHandler( TextInput ); 
    window.Content = textBox;
    window.Show(); 
    new global::System.Windows.Application().Run(); }
  static void TextInput
  ( global::System.Object @object, global::System.EventArgs args )
  { global::System.Console.WriteLine( textBox.Text );  }}

    new global::System.Windows.Input.TextCompositionEventHandler( TextInput );
