is there short way of doing this?

public static string RatingCalculator(string _input)
{
int input = NvUtils.ReturnNumeric(_input);

if (input < 10)
{
return string.Empty;
}
if (input > 10 && input < 20)
{
return "<img src=\"/images/star.png\" alt=\"*\" /><img
src=\"/images/star_empty.png\" alt=\"-\" /><img
src=\"/images/star_empty.png\" alt=\"-\" /><img
src=\"/images/star_empty.png\" alt=\"-\" /><img
src=\"/images/star_empty.png\" alt=\"-\" />";
}
if (input > 21 && input < 40)
{
return "<img src=\"/images/star.png\" alt=\"*\" /><img
src=\"/images/star.png\" alt=\"*\" /><img src=\"/images/star_empty.png\"
alt=\"-\" /><img src=\"/images/star_empty.png\" alt=\"-\" /><img
src=\"/images/star_empty.png\" alt=\"-\" />";
}
if (input > 41 && input < 70)
{
return "<img src=\"/images/star.png\" alt=\"*\" /><img
src=\"/images/star.png\" alt=\"*\" /><img src=\"/images/star.png\" alt=\"*\"
/><img src=\"/images/star_empty.png\" alt=\"-\" /><img
src=\"/images/star_empty.png\" alt=\"-\" />";
}
if (input > 11 && input < 120)
{
return "<img src=\"/images/star.png\" alt=\"*\" /><img
src=\"/images/star.png\" alt=\"*\" /><img src=\"/images/star.png\" alt=\"*\"

Create 6 graphics. 1 for each of the possible states.

all empty
1 filled, 4 empty
2 filled, 3 empty
3 filled, 2 empty
4 filled, 1 empty
all filled

Then, it's simply..

public static string RatingCalculator(string _input)
{
int input = NvUtils.ReturnNumber(_input);
If (input < 10)
{ return "<img src=\"/images/zero_stars.png\" alt=\"no stars\" /> }

if (input >= 10 && input < 20)
{ return "<img src=\"/images/one_star.png\" alt=\"one star\" /> }

if (input >= 20 && input < 40)
{ return "<img src=\"/images/two_stars.png\" alt=\"two stars\" /> }
}

... and so on.

You could even split them into halves like a lot of sites do. Also, you
might want to watch your logic on input. As is, you'd be completely skipping
over the numbers 10, 20, 21, 40, 41, 70 and 71..

Pretty simple and a whole lot less code! ;0)
