学习 Code 总有这样一个过程：入门时候比较依赖设计器、标记语言等辅助工具；等到玩熟练了就会发现纯代码写 UI 其实更高效。而且，纯代码编写也是最灵活的。Windows Forms 项目是肯定可以全代码编写的，哪怕你使用了设计器，它最后也是生成代码文件；而 WPF 就值得探索一下了。咱们知道，WPF 使用 XAML 标记来构建 UI 部分。由于 XAML 扩展了许多功能，用起来自然比 HTML 舒服。但是，老周向来不喜欢标记语言，这也是我向来不喜欢搞前端的原因。尽管某些前端框架模仿 WPF 也搞出数据绑定、MVVM、数据模板之类的名堂，也很难说用得特舒服。
有很多中小型项目都会把 Web 前端部分外包出去，尤其是给私人做——比如一两个人或两三个人做，也不外给其他公司做。有些人总以为前端很火（这里头媒体造势的功劳不小），可往深层一挖，那可不一定了。Web 其实只做了一套 UI 罢了，后端许多是通用模型，既可以和 Web 前端对接，也可以和桌面前端对接，B/S、C/S 通杀的项目也不少。
很多行业软件，如工业医疗，甚至财务、进销存等，还是用成熟的技术好，尤其是桌面技术体验更佳。当然有些行业软件也有 Web UI，纯辅助，一般就是看看报表看看大图查查订单而已。生产力悠关的东西，你还得相信桌面的魅力，娱乐相关的就随便。当然也有用 Web 技术开发桌面UI的框架，这些东西能用但效果不算好，尤其是性能。老周这里说的性能只是要求较宽的性能，而不是苛刻要求下的性能。啥意思呢，就是说用 Web 技术做桌面程序，存在性能问题不需要专用工具测，肉眼就能感觉到严重的性能问题了——吃内存特大，占CPU有亿点高（虽说占得不算恐怖）。这里所说的性能问题要排除 VS Code，因为这货是个奇葩，性能表现挺好。
许多人容易被表面现象迷惑，比如认为招聘信息多的就以为很吃香。那可不一定，有些技术，招聘少并不代表用的人少。老在招聘的顶多说明这些岗位流动性大，这个公司的员工热爱跳槽罢了。近年来 Python 被“利益携带体”们炒得可热了，甚至一些新手以为 Python 是刚出来的新语言。你想多了，就算没有 C 语言早（1972），那也是 80 年代末的东东了。我在学 Python 的时候，估计某些小菜鸟还没出生呢。不要听那些培训班胡说八道，它们的目的是你的钱包，而不是你的码农生涯，它们说话从来不需要负责的。如果你除了 Python 什么都不会的话，那除了会写点“脚毛”外，你什么也干不成。不管你想玩人工智障、视觉神经还是别的东西，你得掌握C语言，特别是想搞更底层的。只会 Py 没准连工作都难找，更别说年薪 500W 越南币了。
在你不知道的领域，你可曾想象，VB6、易语言、Delphi、MFC 还有不少人在用呢。告诉你个秘密，学好汇编可能更吃香，以后会这个的人更少了。信不信由你。当然，积极学习新东西是没错的，这也老周一向主张。不过，你同时得清楚，许多技术之间并不存在相互替代的关系，只不过是你做什么样的程序，就用什么样的技术罢了。比如这桌面程序，你不用纠结，很简单：考虑跨平台的，首选 Qt；仅考虑 Windows 的，那多了去，随便，当然，微软自家自然是最合适的。
可是，一些脑子太灵活的人又纠结了，我选了 Qt，那我用 Widgets 做还是用 QML 做？我选了.NET，那我用 Windows Forms 还是 WPF？还是 MAUI ？对于这种问题，老周送你一句：“像你们这种人是没法改变的，只有滚出码农界”。
好了，上面扯了几段“废腑”之话，回归正题，咱们讨论 WPF，老周这里说的是完全用代码写，指的是一行 XAML 都没有。当然，大伙伴们肯定说那没问题的。构建常规界面绝对行得通，但遇到像数据模板、控件模板、资源字典这些，就得费一点点代码。虽然网上能找到几位同道中人写的小作文，但要么版本太旧，要么过于粗糙。于是老周逮住了这个机会，可以瞎扯蛋一回了。
前文多次强调，咱们就纯代码写 WPF 的，无一行 XAML。所以，默认的 WPF 项目模板咱们就不用了。咱们用控制台应用的模板就行了。来，动手练习一下。
首先，创建一个控制台项目。
  1. dotnet new console -n MyApp -o .
复制代码
dotnet new 命令知道乎？嗯，用来创建项目的，然后是项目模板的名称，console 表示控制台应用程序。模板名字我记不住哟。记它干吗，执行一下下面这一句就能看各种模板了：
  1. dotnet new list
复制代码
这里你可别理解歪了，它不是说用名叫 list 的模板创建项目啊，list 是列出可用的项目模板。然后，你能得到这个表：

咱们平常用得多的都是前几那几个，比如 mvc、web、wpf、classlib 等。我们在命令中引用的就是项目模板的短名称即可。比如控制台就是 console。
-n 参数指定项目的名称，我这里是“MyApp”，-o 参数指定项目存放目录，“.” 表示当前目录。
接下来要改一下项目文件（*.csproj）。
  1. <Project Sdk="Microsoft.NET.Sdk">
  3.   <PropertyGroup>
  4. <NameScope.NameScope>
  5.     <NameScope />
  6. </NameScope.NameScope><OutputType>Exe</OutputType>
  7. <NameScope.NameScope>
  8.     <NameScope />
  9. </NameScope.NameScope><TargetFramework><em><strong>net7.0-windows</strong></em></TargetFramework>
  10. <NameScope.NameScope>
  11.     <NameScope />
  12. </NameScope.NameScope><ImplicitUsings>enable</ImplicitUsings>
  13. <NameScope.NameScope>
  14.     <NameScope />
  15. </NameScope.NameScope><Nullable>enable</Nullable>
  16. <NameScope.NameScope>
  17.     <NameScope />
  18. </NameScope.NameScope><UseWPF><strong><em>true</em></strong></UseWPF>
  19.   </PropertyGroup>
  21. </Project>
复制代码
1、添加 MSBuild 属性 UseWPF，且设置为 true。有了这个你才能在项目中引用 WPF 有关的程序集。同理，如果要使用 Windows Forms，就将 UseWindowsForms 属性设置为 true。
2、TargetFramework 要在.NET版本后加上“-windows”，表示这是 Windows 平台特定的，Linux 上不可用的。类似的如 net7.0-android 等。
至于 OutputType 属性要不要改为 WinExe，.NET 5 以上是不需要的，它会自动判断启不启动控制台窗口。
好了，保存，关闭项目文件。可以写代码了。
在写代码前，咱们先理清楚一些核心对象的关系。你才会知道怎么写。Application 类是 WPF 程序启动的核心对象，通常表示该应用程序相关的初始化。所以，在 Main 方法中记得 new 一个。你可别太聪明，千万不要直接从 Application.Current 静态属性来获取。因为这时应用程序还没初始化呢，Current 属性还是 null。Current 属性适合在项目的其他代码中方便访问 Application 对象而使用的。
如果你没别的东西初始化，那就调用 Application 对象的 Run 方法。应用程序正式启动，并且主线程会卡在（也不是真的卡）这里，直到程序要退出了才从 Run 方法返回。其间，调度器会不断调度/处理各线程上的消息，直到消息循环终止。
窗口应用程序当然要一个主窗口。表示窗口的基类是 Window，可以直接用它，也可以派生出自己的类，然后初始化要在窗口上显示的控件。

Windows 属于内容控件，公开 Content 属性，用来设置单个对象引用。上述代码先创建两个 TextBlock 实例和一个 Button 实例，然后把它们塞进 StackPanel 中，再把 StackPanel 实例赋值给窗口的 Content 属性。
窗口类写好后，在 Main 方法中，调用 Run 方法时把窗口实例传进去。

这个程序已经可以运行了。

 
************************************************************************************************
咱们继续探索。如果要用到数据绑定呢。在 XAML 中是用 {Binding} 扩展标记的，而在代码中对应的是 Binding 类，位于 System.Windows.Data 命名空间。
Binding 类的构造函数可以传递一个字符串常量，对应 {Binding Path=... } 中的 Path，即要绑定的对象路径。数据源则由 Source 属性设置。
  1. public Binding(string path);
复制代码
关联绑定用的是 BindingOperations 类的静态方法 SetBinding，要获取已关联的 Binding 对象就调用 GetBinding 方法。
  1. public static Binding GetBinding(DependencyObject target, DependencyProperty dp);
  2. public static BindingExpressionBase SetBinding(DependencyObject target, DependencyProperty dp, BindingBase binding);
复制代码
BindingOperations 类本身是静态类，所以它的成员自然也是静态的。target 参数是绑定目标，即 WPF 对象，dp 是要绑定的依赖属性，binding 就是Binding对象。
咱们举个例子。
假设用以下类作为数据源。
  1. public class Student
  2. {
  3. <NameScope.NameScope>
  4.     <NameScope />
  5. </NameScope.NameScope>public int ID { get; set; }
  6. <NameScope.NameScope>
  7.     <NameScope />
  8. </NameScope.NameScope>public string? Name { get; set; }
  9. <NameScope.NameScope>
  10.     <NameScope />
  11. </NameScope.NameScope>public int Age { get; set; }
  12. }
复制代码
窗口的结构：内容根为 Grid 对象，它包含三行两列，用来放六个 TextBlock 控件。

ColumnDefinitions 用来定义列。上述代码中，第一列的宽度为 Auto，第二列的宽度为 *。
RowDefinitions 集合用来定义行。上述代码中，三行的高度都是 Auto。
然后 new 出六个 TextBlock，三个用来显示字段标签，三个用于数据绑定，显示属性值。

运行效果如下：

 
这时候，估计你也想到了一件事—— WPF 元素之间的绑定咋弄？对应的 XAML 扩展标记 {Binding ElementName=..., Path=... }。这个用代码写起来也不难，Binding 类有 ElementName 属性，可以引用已命名的对象。但是，在代码里面，咱们是直接用变量名来引用对象的，并没有分配对象名称。虽然 FrameworkElement 类的子类都继承了 Name 属性，但，设置这个 Name 属性 Binding.ElementName 是找不到的，必须要在 NameScope 对象里注册到XAML名称空间后才能被 ElementName 引用。
NameScope 类其实是个 Key=String, Value = Object 的字典，维护当前名称空间范围内的对象列表。对应的是 XAML 中的 x:Name = ...。NameScope 类定义了 NameScope 附加属性，允许将 NameScope 实例设置到目标对象上。XAML 语法是
  1. <NameScope.NameScope>
  2.     <NameScope />
  3. </NameScope.NameScope>
复制代码
但我们在写 XAML 时是不需要，都是自动添加的，用 x:Name 就行了。
在代码中用 SetNameScope 方法设置。
 
看看下面的例子。
  1. void InitUI(){<NameScope.NameScope>
  2.     <NameScope />
  3. </NameScope.NameScope>Title = "元素之间绑定";<NameScope.NameScope>
  4.     <NameScope />
  5. </NameScope.NameScope>// 根据内容自动调整窗口大小<NameScope.NameScope>
  6.     <NameScope />
  7. </NameScope.NameScope>SizeToContent = SizeToContent.WidthAndHeight;<NameScope.NameScope>
  8.     <NameScope />
  9. </NameScope.NameScope>StackPanel panel = new(){<NameScope.NameScope>
  10.     <NameScope />
  11. </NameScope.NameScope><NameScope.NameScope>
  12.     <NameScope />
  13. </NameScope.NameScope>Orientation = Orientation.Vertical,<NameScope.NameScope>
  14.     <NameScope />
  15. </NameScope.NameScope><NameScope.NameScope>
  16.     <NameScope />
  17. </NameScope.NameScope>Margin = new Thickness(15.0d)<NameScope.NameScope>
  18.     <NameScope />
  19. </NameScope.NameScope>};<NameScope.NameScope>
  20.     <NameScope />
  21. </NameScope.NameScope>this.Content = panel;   // 布局<NameScope.NameScope>
  22.     <NameScope />
  23. </NameScope.NameScope>// 文本输入控件<NameScope.NameScope>
  24.     <NameScope />
  25. </NameScope.NameScope>TextBox txt = new TextBox();<NameScope.NameScope>
  26.     <NameScope />
  27. </NameScope.NameScope>txt.Margin = new Thickness(3.0d, 5.0d, 3.0d, 8.5d);<NameScope.NameScope>
  28.     <NameScope />
  29. </NameScope.NameScope>// 给它分配一个名字，绑定时用到<NameScope.NameScope>
  30.     <NameScope />
  31. </NameScope.NameScope>NameScope myScope = new();<NameScope.NameScope>
  32.     <NameScope />
  33. </NameScope.NameScope>NameScope.SetNameScope(this, myScope);<NameScope.NameScope>
  34.     <NameScope />
  35. </NameScope.NameScope>myScope.RegisterName("txtInput", txt);<NameScope.NameScope>
  36.     <NameScope />
  37. </NameScope.NameScope>// 文本块<NameScope.NameScope>

  39. </NameScope.NameScope>TextBlock tb = new TextBlock();<NameScope.NameScope>
  40.     <NameScope />
  41. </NameScope.NameScope>tb.Margin = new Thickness(5.0d, 0d, 5.0d, 0d);<NameScope.NameScope>
  42.     <NameScope />
  43. </NameScope.NameScope>// 绑定<NameScope.NameScope>
  44.     <NameScope />
  45. </NameScope.NameScope>Binding bind = new();<NameScope.NameScope>
  46.     <NameScope />
  47. </NameScope.NameScope>bind.ElementName = "txtInput";<NameScope.NameScope>
  48.     <NameScope />
  49. </NameScope.NameScope>bind.Path = new PropertyPath(TextBox.TextProperty);<NameScope.NameScope>
  50.     <NameScope />
  51. </NameScope.NameScope>bind.Mode = BindingMode.OneWay;<NameScope.NameScope>
  52.     <NameScope />
  53. </NameScope.NameScope>// 在文本框更改时更新数据<NameScope.NameScope>
  54.     <NameScope />
  55. </NameScope.NameScope>bind.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged;<NameScope.NameScope>
  56.     <NameScope />
  57. </NameScope.NameScope>BindingOperations.SetBinding(tb, TextBlock.TextProperty, bind);<NameScope.NameScope>
  58.     <NameScope />
  59. </NameScope.NameScope>// 添加到布局<NameScope.NameScope>
  60.     <NameScope />
  61. </NameScope.NameScope>panel.Children.Add(txt);<NameScope.NameScope>
  62.     <NameScope />
  63. </NameScope.NameScope>panel.Children.Add(tb);}
复制代码
这个方法也是写在 Window 的派生类中，SizeToContent = SizeToContent.WidthAndHeight 表示本窗口的宽度和高度会根据它要显示的内容自动调整。
由于 TextBlock 控件的文本来源于 TextBox，因此，要为 TextBox 注册一个名字“txtInput”。由于 FrameworkElement 类有 RegisterName 方法，所以，注册名称的代码也可以这样写：
  1. NameScope.SetNameScope(this, new NameScope());
  2. this.RegisterName("txtInput", txt);
复制代码
设置 bind.UpdateSourceTrigger = UpdateSourceTrigger.PropertyChanged 允许在输入的内容更改后就马上更新绑定数据，能做到实时显示输入的内容。
效果如下：

好了，今天咱们先说到这儿，剩下的如模板、样式、动画、3D 什么的，咱们下次再探讨。
