c# - ASP.NET Hashed PW's + Salt Confusion -


I am following the MSDN article located here:

My confusion is on the function: 

  Private String String CreatePasswordHash (string pwd, string salt) {string salt and pw = string .concot (pwd, salt); String hashed PWD = form attestation. Hashpswordforstoring sign file (salt and pwd, "SHA1"); HashedPwd = String.Concat (hashed PWD, salt); Return Hashard Power; }

My understanding is that: 1. Share the salt and plain text PWD 2. A hashed pass has been made using Sha1. 3. Repeat the salt with palm pHD which was originally salt in it ???

What is the logic behind Step 3? I've got a function similar to MSDN and where it leaves the last consulate.

I do not understand why the last concocket operation in MSDN version is

It is storing salt with a hacked password so that you can remove the whole thing from the configuration file (or wherever you store it), press the salt on the end, hover the password that comes with it and the configuration from the hashead password Compare the results of If you do not store salt with a hashed password in the configuration, you can store it somewhere and when you do the test, remove it from there to hashed in the incoming password. Since SHA1 is a fixed 160 bit (20bytes), it is easy to hold salt in the hashed password without leaving the first 20 characters.

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

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. 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...
