New to C# Concepts -


I am doing a crash course in C # OOP and I'm curious to know that the "LIST" keyword is the code below Shows in:

var actor = new list & lt; Actor & gt; ();

thanks

list & lt; T & gt; is a class with a type parameter, it is called "generic" and allows you to manipulate objects in a class object, especially for container classes useful for a list or queue.

A container only stores things, it really does not need to know whether it is storage, we can implement it without the generic: 

  Class list {public list} {} Add public null (object to add) {/ * Add to object 'Orange' to / add '*' /} Remove zero (object to revive) {/ * Remove 'toRemove' to make the public public ] [] (Int index) {/ * storage array in index Return value * /}}

However, we do not have type security, I can misuse the hell from that collection: 

  list List = new list (); List Add (1); List Add ("Uh oh"); List Add (2); Int i = (int) list [1]; // boom becomes dynamite

Using generic in C # allows us to use these types of container sections in a safe way. 

  Category list & lt; T & gt; ; {// 'T' is our type, we do not need to know what 't' is, // we should know that it is a type. Public T Operator [] as above / / * as above * as above (as above) /} *

Now if we like Trying to add something that we do not have, we get an error of time, which is done when our program is executed.

list & lt; Int & gt; List = new list & lt; Int & gt; (); List Add (1); // OK list Add ("not at this time"); // does not compile, you know that there is a problem

Hope that's got help. Sorry if I have made any syntax errors there, then my C # is wild;)

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...
