design - why C# does not provide internal helper for passing property as reference? -


This issue is about language design.

Please do not answer the question while reading the entire post! Thank you.

With all helpers present in C # (like Lambadas or automatic properties) it is very strange for me that I can not give property with a reference, suppose I want to do this: / P> 

  foo (ref my_class.prop); I get an error because I write instead:  
  {var tmp = my_class.prop; Foo (tmp); My_class.prop = tmp; }  
 
 And now it works. But please keep in mind the two things: 
 
     
  1.  
     This is a normal template, I have not typed anywhere, only "var", so it applies to all types and number of properties. I 
     
    2.  
  2.  
     I have to do it again and again, there will be no use - this is mechanical work 
     
    3.  
 
 The current problem In fact, it kills such useful works as a swap. Normally swap is 3 lines long, but since it has 2 references, it takes it to 5 lines. Of course this is nonsense and I want to call it all by writing "swap" all the time. But it shows that C # can be saved from reusable code, bad 
 
 Question 
 
 So - if any compiler automatically creates a temporary variable (as I do by hand), and specify values ​​back to values? Is there any danger in it? I am not looking at it so I am curious about what you think that looks like the design of this issue as it looks now. 
 
 Cheers, 
 
  edit  as 280Z28 gave great examples to kill the idea of ​​automatic raping for properties, yet I suppose It is useful to wrap properties with the temporary variables that might be useful: 
 
  swap (inside my_class.prop1, inside my_class.prop2);  
 
 Otherwise, for a real swap, C #: - (

There, for example,

Case 1: 

  int x There are a number of assumptions that give you the meaning and behavior of a  ref  parameter Interlocked.Increment (ref x);

If you can pass an asset in the context of this method, the call will be the same, but it will be

Case 2: 

  zero in Summary: A parameter parameter function passes through the address of the memory location. "By reference, the end of the jar (riff bool trigger) {while the trigger!} Sleep (1000);}

summary: To pass a property, "The implementation of creating a temporary variable will be synonymous to passing meaning, which is the exact behavior that you reject the parameter when creating the referee .

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...
