convert int array to string string

Flattening a numeric array into a string, using loops all the time, the code is simple, but always wants to be more concise, refactoring

int[] Intarray =New int[] {1,2,3,4,5 };stringresult =string. Empty; for(inti =0; i < intarray.length; i++){    if(!string. IsNullOrEmpty (Result)) result+=","+Intarray[i]; Elseresult=Intarray[i]. ToString ();}

Today only know that there are really small tricks, simple cute!

int array goes to a delimited string

int 1 2 3  }; string [] STRs = array.convertall<intstringdelegate(intreturn  Input. ToString ();}); string string. Join ("; ", STRs);

int array to string[] array also does not require write loops

int [] ints={1,2,3,4== (string[]) List.toarray (new String[ints.length]);

int 1 2 3  }; string [] output = array.convertall<intstring> (ints, i = i.tostring ());
