c# - Linq query definition -

-

I am using the Windows Azure Toolkit product on codeplex. It looks right to meet my needs but there are very few examples. Specifically, the Ezoor Tables has a method to obtain data: 

  Get public virtual t (expression & lt; funk & lt; t, bool & gt; & gt; count) {This return.Query.Where (predicate). FirstOrDefault (); } The problem is that there are no examples in the toolkit and I can not understand logic:  
  (expression & lt; funk & lt; t , Bool & gt; & gt; prediction)   
 should look like this  
 Is there anyone with knowledge of Linux and C # that can give me some advice or suggestions   
 
 
 This is just one The predicate, is a method that accepts the parameter type  T  and A Boolean Returns - The easiest way to use it is to pass the lambda expression - simple example:  
  public class Foo & lt; T & gt; {IQueryable & lt; T & gt; Query; Obtain Public Virtual T (Express & lt; Funk & lt; T, bool & gt; Count) {Return JQuery.Where (predicate). FirstOrDefault (); }} ... foo & lt; Int & gt; Foo = new foo & lt; Int & gt; (); Int firstValueUnder100 = foo.Get (x => x & lt; = 100);

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

Python's equivalent for Ruby's define_method? -

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
