out

问题 I have some data that I would like to aggregate, but I'm getting the index out of bounds error, and I can't seem to figure out why. Here's my code: if period == "hour": n=3 tvec_a=np.zeros([24,6]) tvec_a[:,3]=np.arange(0,24) data_a=np.zeros([24,4]) elif period == "day": n=2 tvec_a=np.zeros([31,6]) tvec_a[:,2]=np.arange(1,32) data_a=np.zeros([31,4]) elif period == "month": n=1 tvec_a=np.zeros([12,6]) tvec_a[:,1]=np.arange(1,13) data_a=np.zeros([12,4]) elif period == "hour of the day": tvec_a

问题 I have an issue with a RelativeLayout. It is a custom view for a List Item. I have a RelativeLayout, it's height is set to wrap_content. Inside of it are three Linear Layouts, one of which has it's height set to wrap_content. The other two are set to match_parent as I need them to fill the parent after it has grown to accommodate the wrap_content one. The two that are supposed to grow are behind the other one (it's used for swiping, The top view when swiped moves out of the way to reveal the

问题 I have a bit of COM code that uses interface pointers. The original author of the code implemented functions that return an interface pointer like this: HRESULT Query ( IN BSTR sQuery, OUT IEnumWbemClassObject* &pEnumerator ); // (1) instead of the traditional HRESULT Query ( IN BSTR sQuery, OUT IEnumWbemClassObject** ppEnumerator ); // (2) The function (1) is called like this: hRes = Query ( sQuery, pEnumerator ); // (3) which definitely looks wrong but it works fine. I'm not sure if I'm

问题 Using this construct: var dict = new Dictionary<int, string>(); var result = (dict?.TryGetValue(1, out var value) ?? false) ? value : "Default"; I get an error saying CS0165 use of unassigned local variable 'value' which is not what I expect. How could value possibly be undefined? If the dictionary is null the inner statement will return false which will make the outer statement evaluate to false, returning Default . What am I missing here? Is it just the compiler being unable to evaluate the

问题 I have this string: string input = "1,2,3,4,s,6"; Pay attention to the s character. I just want to convert this string in a List<int> using LINQ. I initially tried in this way: var myList = new List<int>(); input.Split(',').ToList().ForEach(n => myList.Add(int.TryParse(n, out int num) ? num : -1) ); lista.RemoveAll(e => e == -1); But I prefer not have any -1 instead of a no-number characters. So now I try with this: var myList = new List<int>(); input.Split(',').ToList() .FindAll(n => int
