WPF更新绑定字段
很久没用过wpf了,今晚改一个小工具,折腾了半天,记录备忘一下。
在xaml中绑定好上下文字段
设置绑定上下文
var stu = new Student();
this.DataContext = stu;
Student实现INotifyPropertyChanged
public class Student : INotifyPropertyChanged
{
private string _name;
public string Name
{
get => _name;
set
{
_name = value;
OnPropertyChanged();
}
}
public event PropertyChangedEventHandler PropertyChanged;
protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null)
{
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
}
更新
Task.Run((async () =>
{
while (true)
{
await Task.Delay(1000);
stu.Name = DateTime.Now.ToString();
}
}));
