c# - WPF TextBlock文本绑定(bind)

TextBlock绑定(bind)不起作用，我无法弄清楚为什么...

(此代码有效，但TextBlock并未更新)

XAML

<TextBlock x:Name="filterAllText"
 Text="{Binding UpdateSourceTrigger=PropertyChanged}" />

背后的代码

filterAllText.DataContext = LogSession.test.MyCoynt;

C#

public class Test : INotifyPropertyChanged {
 public int myCoynt;

     public int MyCoynt {
        get { return myCoynt; }
        set {
            myCoynt = value;
            NotifyPropertyChanged();
        }
    }

     public event PropertyChangedEventHandler PropertyChanged;

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

最佳答案

试试这个:

<TextBlock x:Name="filterAllText"
    Text="{Binding UpdateSourceTrigger=PropertyChanged, Path=MyCoynt}" />

并将您的DataContext设置为:

filterAllText.DataContext = LogSession.test;
