c# - How does F# deal with the thousands of standard mutable types in the BCL? -


Like price types, point, size, etc.

I too Really irrevocable, do the F # use alternative or irreversible versions of these?

If this standard uses unstable BCL types, will not it compromise with the complete irreversible belief that F # provides both compilation and runtime?

EDIT: What did you mean to ask, if you have alternative irreversible versions of these BCL types, then I do not have to write all these different BCL types with scratches. Or is this the desired behavior that these types (such as point, size, etc.) are still ineligible when using WinForms or whatnot?

You can use types from not BCL (base class library) just fine with F # . Many of these types are volatile, and thus come with the benefits of all associated costs and volatile data.

However, each of these changes can choose to redesign and apply temporary versions of eligible sections, which often work too much. The irreversibility can be a spectrum, not just all or anything, so you can often make the original bits and data structures of your algorithm irreversible, but then use variations when interacting with different Net APIs, It becomes easy to talk. Web services, or iio drag, or whatnot

That said, F # Runtime (FSharp.Core.dll) contains some irreversible collection classes, and (which are almost invariable, are found in the list, hashets, and dictionary organs. Generic, because it is often an irreversible collection, for example it is useful for continuous snapshots in multi-threaded code.

To look at a 'mentality' point, I should think about this: Change in F # encourages state mitigation . Nearly every important app is bound to use the state of some instability, but if you keep your original data structures and algorithms mostly free from instability, you get the benefit of irreversibility for the main part of your code. F # makes it easy to get this benefit in the main part of your code, while still making the volatile state easy to connect, either in the 'spotted' pocket, or around the boundaries of the edges and the communication of your application.

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...
