c# - Anonymous methods with return type in .Net -


This is really a question for my curiosity because I know there are other ways of working around the problem.

There is a property on my "item" class- "mipartatite" - which I want to evaluate through the collection I want to repeat - "My item collection" - and if there is an "item" square The property which is not "MyProperty" is nothing, I have to set a Boolean flag to inform that any of the collection includes a non-faucet microprocessor, its "item" objects. 

  Pure ContainsPF = Function () (MyItemCollectionImage.MyPropertyInot Nothing Selection Item as Item From This ITEM). Count & gt; 0

This gives me the warning of "no convertible expression", as in 'section; Object type is assumed ', so I tried 

  Boolean = function as private content (POF) (MyItemCollection as item from this item where item. MyProperty IsNot is nothing Select items). Count & gt; 0 subc). Mount & gt; 0

Although this can not be converted into 'boolean' of long expression "boolean" is not a representative type "

Does this function anyway Protecting the type of refund or should I just use a different method (an old style function)?

Thank you.

I think you want to declare it as Func (Boolean key) Instead of: 

  Private container PF (boolean key) as funnel = [...]

As far as I can Am See that although the property (according to its first paragraph) is not making it why not declare it as a general asset?

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...
