C# WPF -完全删除对象和所有子对象

public void DeleteObjectAndChildren(UIElement obj)
{
    // Step 1: 从父容器中移除对象
    if (obj.Parent is Panel parentPanel)
    {
        parentPanel.Children.Remove(obj);
    }
    else if (obj.Parent is Decorator parentDecorator)
    {
        parentDecorator.Child = null;
    }

    // Step 2: 释放对象资源
    if (obj is IDisposable disposableObj)
    {
        disposableObj.Dispose();
    }

    // Step 3: 递归删除子对象
    if (obj is Panel panel)
    {
        foreach (UIElement child in panel.Children)
        {
            DeleteObjectAndChildren(child);
        }
    }
    else if (obj is Decorator decorator)
    {
        DeleteObjectAndChildren(decorator.Child);
    }
}
