c# - Set same value to an array/list without using a for loop -

i want set same value specific range of array or list without using loop. follows:

int[] myarray = new int[100];  int lower = 20;  int upper = 80;  int value = 5;  myarray.method(lower,upper,value);

i have tried myarray.setvalue() , mylist.insertrange() allows set 1 value, not range.

is c#-method doing task? done without loop?

well, create temporary array in right size , copy source array

array.copy(enumerable.repeat(value, upper-lower+1).toarray(), 0,            myarray, lower, upper-lower+1);

but that's inefficient (and, internally, enumerable.repeat uses loop, too)

i don't see what's wrong simple for loop:

for(int = lower; <= upper; i++)     myarray[i] = value;
