        <!-- 窗口内容 -->
    </Grid>

public partial class MainWindow : Window

        InitializeComponent();
        DataContext = new WindowViewModel();
    }
}

public class WindowViewModel : INotifyPropertyChanged

    private double _clientWidth = 800;
    public double ClientWidth
    {

        set

        }
    }

    public event PropertyChangedEventHandler PropertyChanged;

    protected virtual void OnPropertyChanged([CallerMemberName] string propertyName = null)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyName));
    }
}

public class WindowViewModel : INotifyPropertyChanged

    public void SetClientSize(double width, double height)
    {

        ClientHeight = height;
    }
}

var windowViewModel = (WindowViewModel)DataContext;
windowViewModel.SetClientSize(1024, 768);
