If your _service.getCardList() returns null then the foreach will throw an exception which you have not handled. Maybe that is the reason you are getting (500) internal server error and not the jquery url, as 500 error code suggests that something went wrong in the server code. As a suggestion, You should use implement try – catch and log the exceptions somewhere to be able to … Read more
The problem is with line Label1.Text may or may not be int. Check. Use Int32.TryParse(value, out number) instead. That will solve your problem.
Each type of integer has a different range of storage capacity As stated by James Sutherland in his answer: int and Int32 are indeed synonymous; int will be a little more familiar looking, Int32 makes the 32-bitness more explicit to those reading your code. I would be inclined to use int where I just need ‘an integer’, Int32 where the size is important (cryptographic code, … Read more
The easiest way I can think of is to use Linq:
You might like IntervalHeap from the C5 Generic Collection Library. To quote the user guide Class IntervalHeap<T> implements interface IPriorityQueue<T> using an interval heap stored as an array of pairs. The FindMin and FindMax operations, and the indexer’s get-accessor, take time O(1). The DeleteMin, DeleteMax, Add and Update operations, and the indexer’s set-accessor, take time O(log n). In contrast to an ordinary priority queue, an interval heap … Read more
The readonly keyword is used to declare a member variable a constant, but allows the value to be calculated at runtime. This differs from a constant declared with the const modifier, which must have its value set at compile time. Using readonly you can set the value of the field either in the declaration, or in the constructor of the object … Read more
EDIT: This is now part of MoreLINQ. What you need is a “distinct-by” effectively. I don’t believe it’s part of LINQ as it stands, although it’s fairly easy to write: So to find the distinct values using just the Id property, you could use: And to use multiple properties, you can use anonymous types, which implement equality appropriately: … Read more
Another option is to simply use the Application log accessible via the Windows Event Viewer. The .Net error will be recorded to the Application log. You can see these events here: Event Viewer (Local) > Windows Logs > Application
There are four things I can think of which need to happen so that OnTriggerEnter gets called: The two objects’ colliders need to actually be overlapping. Just because their rendered pixels are overlapping, doesn’t mean their colliders are overlapping. This can be checked in the editor. Their colliders are indicated with a green outline in the Scene tab. If … Read more
What you are asking about is a topic in computer science known as Algorithm Complexity Analysis. It is a very important topic to consider when writing algorithms, or solutions, in your programs because it relates to run-time, or how fast your computations will run. Big-Oh, or O(n) relates to the upper-bound run-time for an algorithm … Read more
