c# - WriteFile vs TransmitFile for large files that need to be deleted from the server after transfer -


I have to trigger user downloads of large files in the web browser, where I am creating a file to transfer to the server , Then remove it immediately afterwards i get enough examples that i probably should use the feedback. Transmission file or Response The Vir file ... but has problems with both:

The file is synchronous, but it buffer the file in memory before sending the user as I am working with very large files , So it can cause problems.

The transmit file does not buffer locally, so it works for large files, but it is asynchronous, so I can not remove the file later Calling transmit file clearly guarantees the file flushing Is not it that I can remove it either?

What is the best way to deal with this?

Here also there is binary ... I have to copy it into sections, through the loop file stream?

Here's a good solution that uses transmit files, but you

Simply replace the logging with the file removal at the end.

I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
