return a value up vote 21 down vote favorite 1 I've made a basic extension method to add retry functionality to my HttpClient.PostAsync: public static async Task
Not All Code Paths Return A Value In Asp.net C#
logRetry(attempt); try { var response = await httpClient.PostAsync(uri, content).ConfigureAwait(false); response.EnsureSuccessStatusCode(); return response; } catch (HttpRequestException) { ++attempt; if (attempt > maxAttempts) throw; } } } The above code gives me the following error: Error CS0161 'HttpClientExtensions.PostWithRetryAsync(HttpClient, Uri, HttpContent, int, Action)': not all code paths return a value. If I add throw new InvalidOperationException() at the end (or return null for that matter), the error goes away as expected. What I'd really like to know is: is there any code path that actually exits this method without either a value being returned or an exception being thrown? I can't see it. Do I know more than the compiler in this case, or is it the other way around? c# .net dotnet-httpclient share|improve this question edited Nov 9 '15 at 10:18 Thomas Ayoub 17.2k103885 asked Nov 9 '15 at 10:15 Martin Wedvich 960619 Funny question :) –Thomas Ayoub Nov 9 '15 at 10:20 Check stackoverflow.com/questions/22993131/… –MusicLovingIndianGirl Nov 9 '15 at 10:21 3 I would suspect that it's unable to analyse/prove the fact that either the catch block throws or the while block will not terminate. –Damien_The_Unbeliever Nov 9 '15 at 10:25 7 Simply change while

"return" is final. It will quit the function at that point, returning just the first value found in the loop. If there is nothing in dirs (an empty collection) it cannot return anything, so falls out of the foreach loop having done nothing, and hence the error. If there is nothing in the "dirs" collection, what is returned? The simple fix is to add return after the foreach, as a "catch-all" using System; using System.Data; using System.IO; using System.Data.SqlClient; using System.Data.SqlTypes; using Microsoft.SqlServer.Server; public partial class UserDefinedFunctions { [Microsoft.SqlServer.Server.SqlFunction] public static SqlString FindMyLocation(String location) { try { string[] dirs = Directory.GetFiles(@"\\server01\DataFolder", location, SearchOption.AllDirectories); foreach (string dir in dirs) { return dir ; } return null; } catch (Exception e) { string address = "No File"; return address ; } } } However, this does not solve the issue that your function only returns one value, not a collection, as
