How to filter a list from sublist

Question

I have listbox which is bind with a datasource. I have hold all the items of this listbox in to a generic type list as following code.

List<FRReportRow> lstreport = lstSelectRows.Items.Cast<FRReportRow>().ToList();

I have done some code of mouse click for multiextended selection of listbox. These selected items are in same type of another list as following.

List<FRReportRow> reportRow = 
     lstSelectRows.SelectedItems.Cast<FRReportRow>().ToList();

Now I have a checkbox which returns only those items which are not in the reportRow list when i checked the checkbox and I unchecked the checkbox it returns full list as lstreprot . So How can i filter items from lstreport ?

Answer 1

使用Enumerable.Except获取仅存在于lstreport列表中的行（即未选择的行）：

IEnumerable<FRReportRow> notSelectedRows = lstreport.Except(reportRow);
