How to get enumerable range with a variable step count

I am trying to get a list ranging from minimum and maximum values with variable step counts.

For example: If I set minimum value as 10,000, maximum value as 150,000 and step count as 20,000. I should be able to get list as [10000,30000,50000,70000,...,150000].

Similary if step count is set to 15,000 - I should get list as [10000,25000,40000,...,145000]

 int min = 10000;
 int max = 150000;
 int step = 20000;

 var result = Enumerable.Range( min, max).Where(i => i<= max && (i % step == 0));
 foreach (int num in result) { Console.WriteLine(num); } // output: [20000,40000,60000,80000,100000,120000,140000]

Since I am using modulus operator to equate zero value, it is skipping the first value in the range and gives me the above result instead of [10000,30000,..,150000]. Since I am very new to C# programming, can anyone please correct me with the above code to get the desired output.

PS: I have referred this thread How to get alternate numbers using Enumerable.Range? but was unable to find the answer.

Solution

You just need to modify the where condition in your Linq statement:

var result = Enumerable.Range(min, max - min + 1).Where(i => (i - min) % step == 0);

When equating whether the modulo of i vs step was 0, you forgot to subtract the starting value min. By subtracting min, you offset the modulo calculation to compare against the value that is i offset by min as opposed to using i.

Output when step is 20,000:

Output when step is 15,000:
