c# - The name 'GroupforA' does not exist in the current context -


here code:

class program {     static void main(string[] args)     {        list<item> cont1 = new list<item>();       cont1.add(obja); //obja local varible has been defined.        cont1.add(objb); //objb local varible has been defined.        cont1.add(objc); //objc local varible has been defined.        cont1.add(objd); //objd local varible has been defined.        cont1.add(obje); //obje local varible has been defined.        int count = cont1.count;         list<item> cont2 = groupinga(cont1, count);        (int = 0; < cont1.count; i++)       {          console.write(cont1[i].name + " ");//output item's name.        }       console.writeline();       console.write("container 2: ");       (int = 0; < cont2.count; i++)       {          console.write(cont2[i].name + " ");//output item's name.       }     } } 
public class groupitem {     public list<item> groupinga (list<item> obj, int count)     {         list<item> temp = new list<item>();         (int = 0; < count; i++)         {             if (i == count - 1)             {                 break;             }             else if (temp.count > 0 )             {                 break;             }             else             {                 (int j = + 1; j < count; j++)                 {                     bool equal = obj[i].equalfirstphase(obj[j]);                     if (equal == true)                     {                         if (temp.exists(element => element == temp[j]))                         {                             continue;                         }                         else                         {                             temp.add(obj[j]);                             if (temp.exists(element => element == obj[i]))                             {                                 continue;                             }                             else                             {                                 temp.insert(0, obj[i]);                             }                             i--;                          }                      }                 }              }             (int k = 0; k < count; k++)             {                 (int l = 0; l < temp.count; l++)                 {                     if (obj[k].name.contains(temp[l].name))                     {                         obj.removeat(k);                         count--;                      }                 }                 if (obj.count < count)                 {                     k = 0;                  }             }           }         return temp;     } }

i want use groupinga method regroup cont1 cont2. however, there error.

the name 'groupinga ' not exist in current context.

anyone can me??? weak in oop, naming.

you need use :-

groupitem grpitem  = new groupitem();  list<item> cont2 = grpitem.groupinga(cont1, count);

reason:-

your groupinga method non-static , defined in class groupingitem. , trying access program class if method groupinga part of class. accessing non-static methods other classes need instantiate class , use object access class. in case of static method can directly access them . operator on particular class. ex class.method(...)

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
