问题 I am working on a django/wagtail management command (let's call it "file_upload") that does roughly the following: take "csv" argument, which is a full path to a CSV file. parse and open the result using csv for each row, create and save a custom Wagtail Image model object (inheriting from AbstractImage , with a few extra CharField that I do not think prevent me from doing what I want to do) The (currently simplified) CSV looks like this: 1.jpg,Title 1 2.jpg,Title 2 Does not complicated at

问题 How to subtract one list from another? List<string> l1 = new List<string> { "abc", "abc", "abc", "def" }; List<string> l2 = new List<string> { "abc" }; var r = l1.Except(l2).ToList(); Doing this results in r => "def" instead of r=> "abc", "abc", "def". I mean, the second list only contains "abc" one time. So I want to remove only one instance of "abc" of the first list. Btw: Is there a way to check if one list is completely contained in another list? Meaning when list1 only contains "abc" one
