design - Transforming an object implicitly -


The following code shows a pattern that I sometimes see, where the object is transformed into one another Because it is passed as a parameter in a number of method call 

  var o = New MyReferenceType (); DoSomeWorkAndPossiblyModifyO (o); DoYetMoreWorkAndPossiblyFurtherModifyO (o); // now use o ...

This seems to me wrong (it seems difficult to object-oriented). Is it acceptable?

This is acceptable, but generally bad style. As always, the "good" approach is: 

  twosmwork and authoring (& amp; o); // Clear reference means we will accept changes o = DoSomeWorkAndReturnModified (o); // More elastic because you often want to keep the original

The approach you presented is understandable when oh is huge, and it's making a copy in memory, the question Do not use it, or if it is a function then you (and some other = private) do not use it often and do not want to bother with & amp; Sentence - Configuration. Otherwise it is laziness that there are some difficulties in identifying the bug.

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...
