Why is count used instead of array length

Question

Please I am a beginner to programming, why is count used in the for loop so far it is 0 and not if i is less than the number array length.

count = 0
for (int i = 0; i < count; i++)
if (numbers[i] == searchNumber)
found = true;
if (found)
Console.WriteLine("Number {0} found a amount of {1} "
, numbers[i]);
else
{
Console.WriteLine("Not found");
found = false;
}
break;
