在WPF中,可以使用Binding對象來綁定文件。以下是綁定文件的方法:
<Image Source="{Binding ImagePath}" />
public class MainViewModel : INotifyPropertyChanged
{
private string _imagePath;
public string ImagePath
{
get { return _imagePath; }
set
{
_imagePath = value;
OnPropertyChanged("ImagePath");
}
}
public event PropertyChangedEventHandler PropertyChanged;
protected void OnPropertyChanged(string propertyName)
{
PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
}
}
MainViewModel viewModel = new MainViewModel();
viewModel.ImagePath = "C:/path/to/image.png";
this.DataContext = viewModel;
通過以上步驟,便可以實現在WPF中綁定文件路徑并顯示文件內容。
