Hands-On Parallel Programming with C# 8 and .NET Core 3

Handling exceptions from multiple tasks

Now, we'll create multiple tasks and then try to throw exceptions from them. Then, we'll learn how to list different exceptions from different tasks from the caller:

static void Main(string[] args){    Task taskA = Task.Factory.StartNew(()=> throw      new DivideByZeroException());    Task taskB = Task.Factory.StartNew(()=> throw      new ArithmeticException());    Task taskC = Task.Factory.StartNew(()=> throw      new NullReferenceException());    try    {        Task.WaitAll(taskA, taskB, taskC);    }    catch (AggregateException ex)    {        foreach (Exception innerException in ex.InnerExceptions)        {            Console.WriteLine(innerException.Message);        }    }    Console.ReadLine();}

Here is the output when we run the preceding code:

In the preceding code, we ...
