    {
        g.drawString("Hello, world!", 100, 50);
    }
}

JavaScript

JavaScript是一种脚本语言。最广泛用于HTML文件中，也可以用在其它宿主环境下，比如Microsoft® Windows® 脚本宿主（WSH）和一些web服务环境。

用于HTML中：

alert("Hello, World!");
//或者
document.write("Hello, World!");

用于WSH中：

WScript.Echo("Hello, World!");

PostScript

PostScript是一种专门用来创建图像的语言，常用于打印机。

  x:Class="XAMLSample.Page1"
 >
  <Button Click="HelloWorld" Name="Button1">Click Here</Button>
 </Page>

接着使用 C# 建置

 using System;
 using System.Windows;
 using System.Windows.Controls;
 
 namespace XAMLSample
 {
  public partial class Page1 : Page
  {
    void HelloWorld(object sender, RoutedEventArgs e)
