design by contract - How do I get Entity Framework to use interfaces on the generated classes? -


I have a project where the client is using the Entity Framework, and I want to remove the generated class from the rest I am trying to apply.

There is an income class category and it calls the form as a property.

I have created an interface that I want to apply the class like: 

  Public Interface ICategory {string type {get; Set;}}

I did it before SQL in SQL and it works fine. I am creating a partial class in a separate file and I am implementing the interface: 

  public partial category category: iCATTAR // applicable interface

However, whenever EF tries to make a query with EF, then it says that type the type > ().

Example: 

  var query = from DataContext in the c category where type == select "some type" c; Var resultsList = query.OfType & lt; ICATT & gt; (); // error here (not supported)

What am I doing wrong here?

By keeping in mind the other things: I am developing it in silver applications and data. The reference is being pulled from a service, hence there is a customer server connection here too. .

As a general rule, LINQ can only understand the units that your unit Models (ADMX) are part of. So when you are free to expand your unit types, there are partial classes, you can not use properties, methods, and interface references that add you to unit queries in LINQ, however

< P> However, in this case the following questions should give you the results you want: 

  var resultsList = query.Select & lt; ICategory & gt; (C = & gt; c);

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...
