c# - File.Copy() sync or asycn? -


I am using the file. To copy the code (source, destination, true) from local to remote overwrite option. In my case, Dest is a mapped network drive: 

  file. Copy (source, destination, true); UnMapDrive (); // Unmap network drive

The problem I have is that the source file may be locked so that I will not be able to remove the file from the local.

I think this may be due to the file. Copy () The call is not certain whether it syncs a process or not. In other words, what is the source file released after the call?

Yes, it is issued and file. Copy method prevents execution until the copy operation is complete.

The file may be available for reading, but may be locked for deletion.

Check with what process the source file is locking.

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...
