Question

我使用wcf来执行插入数据的任务。我正在使用wcf void函数之一来插入用户数据

AceVqbzServiceClient aceVqbzClientService = new AceVqbzServiceClient();
aceVqbzClientService.OpenAsync();
IAceVqbzService aceVqbzTypeService = aceVqbzClientService as IAceVqbzService;

Task.Factory.FromAsync(
            aceVqbzTypeService.BeginSaveUserOrganizationLinking,
            aceVqbzTypeService.EndSaveUserOrganizationLinking,
            objUser_OrganizationDetail, 
            TaskCreationOptions.None);

aceVqbzClientService.CloseAsync();

这是函数

当我使用时，功能没有给出任何问题，但数据没有通过此插入。请给我解决方案，以便我可以实现这个

Answer 1

您需要异步等待（await）从Task返回的FromAsync：

public async Task FooAsync()
{
    AceVqbzServiceClient aceVqbzClientService = new AceVqbzServiceClient();
    await aceVqbzClientService.OpenAsync();
    IAceVqbzService aceVqbzTypeService = aceVqbzClientService as IAceVqbzService;

    await Task.Factory.FromAsync(
                       aceVqbzTypeService.BeginSaveUserOrganizationLinking,
                       aceVqbzTypeService.EndSaveUserOrganizationLinking,
                       objUser_OrganizationDetail, TaskCreationOptions.None);

    await aceVqbzClientService.CloseAsync();
}

这是我的问题的答案

 try
        {
            AceVqbzServiceClient aceVqbzClientService = new AceVqbzServiceClient();
            aceVqbzClientService.OpenAsync();
            IAceVqbzService aceVqbzTypeService = aceVqbzClientService as IAceVqbzService;

            var asyncResult = aceVqbzTypeService.BeginSaveUserOrganizationLinking( objUser_OrganizationDetail, null, null );
            asyncResult.AsyncWaitHandle.WaitOne();


        }
        catch ( Exception ex )
        {
            throw;
        }

这行代码工作正常

如何在Task.factory.fromAsync中使用void方法
