You can add HOC with exception handling and then check success.

 class Program
{
    static async Task Main(string[] args)
    {
        var itemsToProcess = new[] { "one", "two" };
        var results = itemsToProcess.ToDictionary(x => x, async (item) =>
        {
            try
            {
                var result = await DoAsync();
                return ((Exception)null, result);
            }
            catch (Exception ex)
            {
                return (ex, (object)null);
            }
        });

        await Task.WhenAll(results.Values);

        foreach(var item in results)
        {
            Console.WriteLine(item.Key + (await item.Value).Item1 != null ? " Failed" : "Succeed");
        }
    }
