问题 I want to dynamically load JSON from a URL in C# I tried this code, but not load the array: using Newtonsoft.Json; using (var webClient = new System.Net.WebClient()) { var url = "https://api.coinmarketcap.com/v1/ticker/808coin/" var json = webClient.DownloadString(url); dynamic array = JsonConvert.DeserializeObject(json); var nome = array.name.ToString(); Label33.Text = nome; } 回答1: Using the following class definition, you can deserialize directly to C# values (as strings). From there, you

问题 I have a function that produces some output like this date cashflow count etc 1/1/2000 40 3 ... always a one-liner. This is created many times, with same or different dates. Now I would like a record of all results date cashflow count etc 1/1/2000 40 3 ... so if a new result comes in with the same date / index, than it should add and update the field, i.e. via "+=", however if its a different date that does not already exists in the table, than it should just append and provide basis for

问题 Diff conditions: how to clear dynamic legends at the end of each iteration; how to remove fitted linear lines at the end of each iteration.

I have seen BCEL, CGLIB and some other open source tools for this, but

问题 I have a simple C++ code where I define a dynamic array as: std::vector<double>IPWeights; and then pass it to a function called reference with a reference (so I changed its content) like: void reference (std::vector<double> &IPWeights) and then in my main function, after I changed my arrays content I wanted to print it like: int size_weights=IPWeights.size(); for (int i=0; i<size_weights; i++) { std::cout<<IPWeights[i]<<std::endl; } but in the screen I only see "segmentation fault 11". where
