C#wpf窗体可以移动

1、窗体设置

PreviewMouseLeftButtonDown="Window_PreviewMouseLeftButtonDown"
PreviewMouseMove="Window_PreviewMouseMove"
PreviewMouseLeftButtonUp="Window_PreviewMouseLeftButtonUp">

2、程序设置

public partial class Window3 : Window
{

    Point _pressedPosition;
    bool _isDragMoved = false;
    //窗体可以拖动
    void Window_PreviewMouseLeftButtonDown(object sender, System.Windows.Input.MouseButtonEventArgs e)
    {
        _pressedPosition = e.GetPosition(this);
    }
    void Window_PreviewMouseMove(object sender, System.Windows.Input.MouseEventArgs e)
    {
        if (Mouse.LeftButton == MouseButtonState.Pressed && _pressedPosition != e.GetPosition(this))
        {
            _isDragMoved = true;
            DragMove();
        }
    }
    void Window_PreviewMouseLeftButtonUp(object sender, MouseButtonEventArgs e)
    {
        if (_isDragMoved)
        {
            _isDragMoved = false;
            e.Handled = true;
        }
    }
}
