MultipartFormDataStreamProvider清理 [英] MultipartFormDataStreamProvider Cleanup

问题描述

如果文件发布到我的Web应用程序，那么我将通过 MultipartFormDataStreamStreamProvider.FileData 读取它们.

If files are posted to my webapp, then I read them via MultipartFormDataStreamProvider.FileData.

我这样初始化提供程序:

I Initialize the provider like this:

string root = HttpContext.Current.Server.MapPath("~/App_Data");
var provider = new MultipartFormDataStreamProvider(root);

并且提供程序很好地将它们存储为〜App_Data/BodyPart_ {someguid}"但是，用完这些文件后，如何清理这些文件?

And the provider nicely stores them as "~App_Data/BodyPart_{someguid}" But how do I clean up those files after I'm done with them?

推荐答案

我知道这个问题很旧，但是发现删除临时文件的最佳方法是在处理它之后.

I know this question is old, but the best way I found to delete the temporary file was after processing it.

string root = HttpContext.Current.Server.MapPath("~/App_Data");
var provider = new MultipartFormDataStreamProvider(root);

foreach (var file in provider.Files)
{
    // process file upload...

    // delete temporary file
    System.IO.File.Delete(file.LocalFileName);
}
