删除文件似乎不起作用 [英] Deleting a file doesnt seem to work

问题描述

 我正在尝试使用Windows :: Storage :: StorageFile :: DeleteAsync（）方法删除文件。但它似乎没有用。错误代码返回0. 该文件永远不会被删除。难道我做错了什么？

 I am trying to delete a a file using Windows::Storage::StorageFile::DeleteAsync() method. But it doesnt seem to work. The errorcode returns 0.  The file never gets deleted. Am I doing something wrong?

自动statusOperation = tempFile-> DeleteAsync（StorageDeleteOption :: PermanentDelete）;

    &NBSP ;          statusOperation->完成= REF新AsyncActionCompletedHandler（[]（IAsyncAction ^ asyncInfo）

            &NBSP ;   {

                    汽车错误码= asyncInfo->错误码;

               } ）;;
                statusOperation-> Start（）;

auto statusOperation = tempFile->DeleteAsync(StorageDeleteOption::PermanentDelete);
               statusOperation->Completed = ref new AsyncActionCompletedHandler([](IAsyncAction ^asyncInfo)
                {
                    auto errorcode = asyncInfo->ErrorCode;
                });
                statusOperation->Start();

推荐答案

请注意 IAsyncAction
界面中未定义启动方法。因此，您的代码无法通过编译。

Please note that Start method is not defined in IAsyncAction interface. So your code cannot pass compilation.

请尝试以下代码段。

任务< void>（tempFile-> DeleteAsync （StorageDeleteOption :: PermanentDelete）.then（[this]（）{......}）;
