如何更改WPF XAML以反映C＃代码中的更改？ [英] How to change the WPF XAML to reflect changes in the C# code-behind?

问题描述

我从样本中折叠代码：

• 24.129.21。主要细节绑定
  
  从 C＃/ CSharp教程»Windows Presentation Foundation»Binding）

• 24.129.21. Master Detail Binding
  from C# / CSharp Tutorial » Windows Presentation Foundation » Binding)

我来到了以下C＃代码隐藏，运行同样的XAML： p>

I came to the following C# code-behind, running with the same XAML:

namespace WpfApplication1 
{
    public class Skill
      {
        public string Description { get; set; }
      }

      //I'd like to comment out the next line
      public class Skills : ObservableCollection<Skill>{  }

        public class Employee 
      {
        public string Name { get  ; set; }
        public int Age  { get; set; }
        //public Skills Skills { get; set; }
        //instead of line above - works!
        public ObservableCollection<Skill> Skills { get; set; }
      }

      public class Team : ObservableCollection<Employee> { }

      public class Company
      {
        public string CompanyName { get  ; set; }
        public Team Members { get  ; set; }
      }

      public class Companies : ObservableCollection<Company> { }

      public partial class MainWindow : Window
        {
        public MainWindow()
      {
          InitializeComponent();
      }
    }
}

从

• 公开技能技能{get;组; $


to

• public ObservableCollection< Skill>技能{get;组;

• public ObservableCollection<Skill> Skills { get; set; }

在 Employee class

因此，我想摆脱，即注释掉这一行：

Consequently, I'd like to get rid of, i.e. to comment out the line:

public class Skills : ObservableCollection<Skill>{  }

但我得到： / p>

but I'm getting:

错误1标签技能不存在于XML命名空间
'clr-namespace中： _24_129_21_Master_Detail_Binding。第13行位置34

Error 1 The tag 'Skills' does not exist in XML namespace 'clr-namespace:_24_129_21_Master_Detail_Binding'. Line 13 Position 34

在 Window1.xaml

<local:Team>
  <local:Employee Name="Larry" Age="21">
    <local:Employee.Skills>
       <local:Skills>

推荐答案

在您的 Window1.xaml 类中删除对技能的引用类：（例如< local：Skills> ），因为你没有技能类。相反，您需要在您的ObservableCollection内部获取一些技能元素：

In your Window1.xaml class remove the reference to the skills class: (e.g. <local:Skills> ) since you don't have a Skills class anymore. Instead you want a number of Skill elements inside your ObservableCollection:

<local:Team>
   <local:Employee Name="Larry" Age="21">
     <local:Employee.Skills>
        <local:Skill />
        <local:Skill />
       ....

此外，您应该可以初始化技能 ObservableCollection在Employee的构造函数内。

Also, you should probably initialize the Skills ObservableCollection inside the Employee's constructor.
