GetMerchantRequest从程序中调用，此方法的目的是基于查询获取一些数据，然后从结果集中通过调用外部服务来处理每个成员，然后在服务返回响应后，使用UpdateProcessedTransaction方法更新数据库表
但是，当我调试时，它正在遍历记录并调用SendTransactionsToMerChantAsync。但是，此后程序因错误终止
程序“ [12400] ServiceV2.exe”已退出，代码为0（0x0）。
我不怎么想。.Task。WhenAll是我认为的罪魁祸首...但是，请您检查一下代码，让我知道我做错了什么。
我还更新了SendTransactionsToMerChantAsync，使其仅使用Console.WriteLine（），但仍然退出并出现代码0错误
public static Task<int> SendTransactionsToMerChantAsync(List<Guid> listOfSubscribersToProcess, DataTable dtListofTransaction)
{
return Task.Run<int>(() =>
{
foreach (var guid in listOfSubscribersToProcess)
{
Console.WriteLine("Executed Thread.. " + Thread.CurrentThread.ManagedThreadId);
}
return 1;
});
}
谢谢，感谢您的帮助。
