try-catch

问题 I'm running a command in Powershell through VSTS to affect Azure. The command works, but it gives an error after. The params and connection are working as evidenced by the fact that the group gets permission from the command. I figure a workaround is to put the command in a try block, have it run, and then when the error comes up go to the catch block and end without throwing the error. When I run this script, I still get the same error, like the try block is ignored. Do I have the syntax

问题 Right now my app is crashing when a collection already exists in Firebase Firestore. I want to catch this error when it happens, but my current implementation doesn't catch anything as the addSnapshotListener() method does not throw any error. Current Code let db = Firestore.firestore() do { try db.collection(chatName).addSnapshotListener { (Query, Error) in if Error != nil || Query?.documents != nil { let alert = UIAlertController(title: "Chat Name Already Exists", message: "This chat name

问题 My problem is very simple. I have a try/except code. In the try I have some http requests attempts and in the except I have several ways to deal with the exceptions I'm getting. Now I want to add a time parameter to my code. Which means the try will only last for 'n' seconds. otherwise catch it with except. In free language it would appear as: try for n seconds: doSomthing() except (after n seconds): handleException() this is mid-code. Not a function. and I have to catch the timeout and

问题 I thought I had understood how exception handling in C# works. Re-reading the documentation for fun and self-confidence, I have run into problems: This document claims that the following two code snippets are equivalent, even more, that the first one is translated to the latter one at compile time. using (Font font1 = new Font("Arial", 10.0f)) { byte charset = font1.GdiCharSet; } and { Font font1 = new Font("Arial", 10.0f); try { byte charset = font1.GdiCharSet; } finally { if (font1 != null)
