推荐答案

仅当您的列表"视图试图容纳太多项目时，您才会遇到问题.我可以看到的唯一替代方法是使用虚拟模式.这样，您将不会在列表视图的实例中保留所有数据的副本.

请参阅参考资料以获得解释和代码示例: http://msdn.microsoft. com/en-us/library/system.windows.forms.listview.virtualmode.aspx [

You can only have problems if your List view is trying to hold too many items. The only alternative I can see is using the virtual mode. In this way, you will not keep a copy of all your data in the instance of your list view.

See for explanation and a code sample: http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.virtualmode.aspx[^].
