c# - LINQ to DataSet Dataclass assignment question -


Text after "

I am working on a Silverlight project while accessing a database dataset using LINQ, and then through Silverlight Send data to ASMX Web Service

I defined my dataset using the Server Explorer tool (I am interested in dragging and dropping all the different tables) to use the dataset server and database without any problem Enabled.

The code for one of my web methods is given below: 

  Public listing & lt; ClassSpecification & gt; GetSpecifications () {DataSet2TableAdapters.SpecificationTableAdapter Sta = New DataSet2TableAdapters.SpecificationTableAdapter (); . Return to Sta.GetData () (AsEnumerable with New ClassSpecification Selection) (Specification = Spec.Field & LT; String & gt; ("Specification"), SpecificationType = Spec.Field & LT; String & gt; "SpecificationType"), StatusChange = Spec.Field & LT; Date Time & gt; ("StatusChange"), Tip = Spec.Field & LT; Integer> ("Tip")} ToList & Lt; ClassSpecification & gt; (); }

I have created a "class classification" data square which contains my data and has all the table field properties in it as I

My question is this Is there a faster way to perform assignments compared to what is shown here? In fact, there are about 10 more fields, and I imagine that since my dataset knows the definition of my table, I would have a faster way of assigning more assignment than going into field area. I just tried to choose "New Class Classifications (). ToList

Any help would be greatly appreciated.

First, I will suggest testing of various possibilities using LINQPad, which is free and horrible.

I can not quite miss what you can do with table adapter , But you should be able to use the dataset data you want to receive, such as on For the 

  string imagery = myDataSet.MyTable.Rows [0] // or FindBy ... or you are still selecting a line .Specification;

Then you may be able to do this 

  foreach (the top row in myDataSet.MyTable.Rows) {string fantasy = row.Specification ...}
return (select the new class display () explanation from the line in myDataSet {Specification = Row} Explanation, Specification Type = Row. Explanation Type, Change Status = Pt Ti Change Ktats, Spacey = line. SPE,}). Telst & lieutenant; Understanding classifier & gt; ();

Or even 

  back to myDataSet.Specification.Cast < ClassSpecification & gt; ()

Not sure if the last one will work, but you can see that there are many ways to get what you want. Apart from this, the line has been typed strongly in my tests, so you should not have to create a new class to insert data - you should be able to use the existing "Specification" class (in fact, me Believe it is.)

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...
