c# - Simple Delegate (delegate) vs. Multicast delegates -


I have gone through several articles, but I am still not clear about the difference of general representatives who Generally create and multicast representatives. 

  Public representative Zero MyMethodHandler (object sender); MyMethodHandler handler = New MyMethodHandler (Method1); Handler + = Method 2; Handler (someObject);

The above representative MyMethodHandler will call these two methods, now where the multicast representatives come in. I have read that they can call many ways but I am afraid my basic understanding about the representatives is not correct.

It tells very well: 

  Representative Del ( String s); Class Test Class {Static Zero Halo (String) {System.Console.WriteLine ("Hello, {0}!", S); } Steady zero goodbye (strings) {System.Console.WriteLine ("Bye, {0}!", S); } Fixed Zero Main () {Del A, B, C, D; // rep refers to an object / method hello: a = hello; // Build the representative object b, reference / method method: b = bye; // Two reps, A and B, C: C = A + B are made in the form of; // Remove from the prepared representative, except D, which only says method bye: d = c - a; System.Console.WriteLine ("One representative invited:"); one A'); System.Console.WriteLine ("Invitation representative b:"); B ("b"); System.Console.WriteLine ("Invitation Representative c:"); C ("C"); System.Console.WriteLine ("Invitation representative d:"); watch'); }} / * Output: Invite Representative one: Hello, A! Inviting Representative: B. Goodbye, B! Invitation representative c: Hello, C! Goodbye, C! Delegate Representative D: Goodbye, D! * /

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...
