c# - Zip Mime Type appears unrecognised -


I am trying to return a zip file, as a stream on a browser. It works fine with other types of files (like Excel files), but when I start working with zip files, I do not have to recognize my browser as it's a zip.

Both Firefox and IE are running on my test, with the machine prompt, opening the file to the program to be asked. The Explorer Zip file is set as the default for the union.

IE does not report much back, Firefox still tells me what file type is

application / zip

where As far as I can tell, the correct mime type for the zip file. The only thing I have not set up is that extension, so the file is called 'test' instead of 'test.zip', but as far as I knew that everyone should understand the mime way.

Anyone can be wrong but have any thoughts?

Includes ensuring you file, file extension: 

 Content-Properties : Attachment; File name = test.zip

as the header.

in C #: 

  response. Contact type = "app / zip"; Response.AddHeader ("content-length", contentLength.ToString ()); Response.AddHeader ("content-type", "attachment; file name =" + filename); If (Request.UserAgent.Contains ("MSIE")) {Response.AddHeader ("Content-Transfer-Encoding", "Binary"); }

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. 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...
