Common causes of Cyclomatic Complexity and their solutions -


At work we are looking at common problems that lead to high cyclamatic complexity, for example, if large Having a statement can have high cyclamatic complexity, but can be solved by changing the conditions with polymorphism. What other examples did you find?

See NDepend

There is also a great code metric.

Cyclamatic complexity can be taken in a process that is a popular procedural software metric equivalent to the number of decisions. In Concrete, the CC1 + {{Method of the following expression found in the body of the law}: A method in C #:

if. While For Forex Currency | Case Default | Continue | Goto | & Amp; & Amp; | || | Catch | Ternary operator ?: |

The following expressions have not been calculated for CC calculation:

and | Do it Switch | Try Use | Throw | | Finally Return | Commodity creation | Call method Area Access

Optimized for the OO world, this metric is defined on both methods and classrooms / structures (the amount of your methods in the form of CC). Notice that the CC of an unknown method is not counted when calculating the CC of its external method.

Recommendations: More than 15 cc, where it is difficult to understand and maintain, in which the cc is more than 30, they are extremely complex and should be divided into smaller methods (except if they are automatically Are generated by a device).

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...
