Multiples of 3 C#

Question

I took on the challenge and came up with this:

using System;
using System.Collections.Generic;

namespace SoloLearn
{
class Program
{
static void Main(string[] args)
{
int number = Convert.ToInt32(Console.ReadLine());
int value;

//your code goes here
while(value < number) {
if(value % 3 == 0) {
Console.Write("*");
value++;
}
else {
Console.Write(value);
value++;
}
}

}
}
}

yet it comes out with an error, can anyone help?
