C# WPF简单绑定代码隐藏

我试图学习WPF，我在基本绑定方面有问题，一开始我想在代码背后设置绑定。谁能知道我做错了什么

菲尔斯

public partial class BindInCodeBehind : Window, INotifyPropertyChanged
{
    private string _myText;

    public string MyText
    {
        get { return _myText; }
        set
        {
            _myText = value;
            OnPropertyChanged("MyText");
        }
    }

    public BindInCodeBehind()
    {
        InitializeComponent();

        var bind = new Binding();
        bind.Source = MyText;
        bind.Path = new PropertyPath("Content");

        MyLabel.SetBinding(Label.ContentProperty, bind);

        MyText = "New tekst";
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null)
    {
        PropertyChangedEventHandler handler = PropertyChanged;
        if (handler != null)
        {
            handler(this, new PropertyChangedEventArgs(propertyName));
        }
    }
}

文件XAML

<Window x:Class="WpfBindingLearn.BindInCodeBehind"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="BindInCodeBehind" Height="300" Width="300">
    <Grid>
        <Label Name="MyLabel" Content="Wait for binding"></Label>
    </Grid>
</Window>

路径是相对于当前绑定源设置的。您的源（是
字符串
）没有
内容
属性。您可以将
Source
设置为
Window
和
Path
设置为
MyText

var bind = new Binding();
bind.Source = this;
bind.Path = new PropertyPath("MyText");
