首先在xaml中添加事件

<Window PreviewMouseLeftButtonDown="Window_PreviewMouseLeftButtonDown"PreviewMouseMove="Window_PreviewMouseMove"PreviewMouseLeftButtonUp="Window_PreviewMouseLeftButtonUp"/>

然后脚本输入

Point _pressedPosition;
bool _isDragMoved = false;#region 窗口移动private void Window_PreviewMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{_pressedPosition = e.GetPosition(this);
}private void Window_PreviewMouseMove(object sender, MouseEventArgs e)
{if (Mouse.LeftButton == MouseButtonState.Pressed && _pressedPosition != e.GetPosition(this)){_isDragMoved = true;DragMove();}
}private void Window_PreviewMouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{if (_isDragMoved){_isDragMoved = false;e.Handled = true;}
}#endregion

效果图：
