需要语法帮助

Question

Can someone help with the following:

CollectionView.Filter = m => ((Customer)m).Name.ToLower().Contains(_lastNameFilter);

Instead of looking up name, I'd to search DateAdded = _filterDate

Answer 1

我不知道CollectionView.Filter工作原理，但是为什么不使用它：

CollectionView.Filter = m => ((Customer)m).DateAdded == _filterDate;

Answer 2

It looks like it should be:

CollectionView.Filter = m => 
    ((Customer)m).DateAdded == DateTime.Parse(_filterDate);

Answer 3

假设_filterDate是一个字符串并且DateAdded一个Date CollectionView.Filter = m =>（（Customer）m）.DateAdded == DateTime.Parse（_filterDate）;
