c# - VB.NET Execution Order -


i working on converting vb source code on c#. while understand there converters automate this, , use particular dll without rewriting it, i'm doing partially can understand vb better. not expect write it, it's @ least helping me able read it.

in doing though, i've come across quite confusing. following code snippets examples, i've seen throughout program.

vb source code:

friend function allocateobjectnumber() long     allocateobjectnumber = _nextfreeobjectnumber     _nextfreeobjectnumber += 1     _objectallocatedcount += 1 end function

my translated c# code:

    internal long allocateobjectnumber()     {         cvnextfreeobjectnumber += 1;         cvobjectallocatedcount += 1;         return cvnextfreeobjectnumber;     }

what i'm not understanding flow control vb uses. understand allocateobjectnumber += 1 used in place of return cvnextfreeobjectnumber, if line comes before incrementing of 2 variables, how code not considered unreachable? based on c# understanding, first line in method return calling method, , whole method act pseudo-property.

any helpful explanations?

the vb approach more similar storing value in temporary variable:

internal long allocateobjectnumber() {     var nextnumber = _nextfreeobjectnumber     cvnextfreeobjectnumber += 1;     cvobjectallocatedcount += 1;     return nextnumber; }

in vb function = value syntax doesn't return - code after can keep running. when method reaches end, value used becomes 'return' value whatever called in first place.

you can use function = value syntax multiple times in same method way of returning different result in different conditions without needing temporary variable used in example.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
