I want to add a filter textbox to an application so that when a user types text into it, as they type it, the DataGridView will automatically trim down what's being viewed.
我想在应用程序中添加一个过滤器文本框，以便当用户在输入文本时，DataGridView会自动删除正在查看的内容。
Right now DataGridView is bound to a List with my User Objects.
现在，DataGridView与我的用户对象绑定到一个列表。
I was in the process of just using LINQ to create a separate List of User objects and then just re update the DataGridView by doing the whole dataGridView1.DataSource = filteredList but is that the best way to go about this? I feel like I'm doing it the bad way.
我正在使用LINQ创建一个单独的用户对象列表，然后通过执行整个dataGridView1重新更新DataGridView。DataSource = filteredList但这是最好的方法吗?我觉得我这样做很不好。

That's probably similar to what I'd go with. Alternatively you could iterate the list and remove any objects no longer matching which will probably be much more memory-friendly.
这可能和我的想法很相似。或者，您可以迭代列表并删除不再匹配的任何对象，这可能更有利于内存。

Your "filteredList" should be a bindingList just so you create a direct interaction between the list and the grid (modifying the grid will modify the list without you having to do any more step).
您的“filteredList”应该是一个bindingList，这样您就可以在列表和网格之间创建一个直接的交互(修改网格将修改列表，而不需要做更多的步骤)。
