C# Add int numbers to a list while running a loop

Question

I have tried to get the point across in the title as best as I can but basically what I want to do is add certain items to List while running a loop so I don't have to manually put them into an if statement. Let me please show an example so that I can explain properly.

Example :-

What I need is :- the first number would be 500 and that would be in index 0, then i want a loop to add 150 to the last number generated so that the int list would look like this,

index 0 = 500
index 1 = 650
index 2 = 800
index 3 = 950

Do this repeatedly until say the last number will read 2,000,000

Now I believe that this would be simple to run a loop and base it on conditions but I can only seem to figure out to run a loop that will increment the value in 1.

Hope I have explained well enough

Regards, M

public void GenerateList() { listlevel = new List<int>(); for (int i = 500; i <= 2000000; i += 150) { listlevel.Add(i); } } — Marca

This is not true, you can adjust the increment of the iterator as you wish.

var numbers = new List<int>();
for(int i=500; i<=2000000; i+=150)
{
    numbers.Add(i);
}

For further information on this, please have a look here.

Ah that's fantastic I didn't know you could do that I should of read the documentation better, Ive put that in now and I have around 13k indexes which is perfect now, also tricky is the next step so I now have a value of say 2145 I now want to search the list for the index number that would be say lower than the next index position but higher than the one below if that makes sense?

@Marca please try to plan a solution for this and then try to implement it. If you don't make it, visit Stack Overflow and show your effort and where you got stucked :) But please define your problem crystal clear in paper and think about it. This will improve your problem solving skills.

@Christos yup I am trying to code it as we speak :) so currently trying to search the list if the number I have is greater than the one in the list and hoping at the point it stops will give me my index

public void CheckIndexNumber(int XP) { for (int i = 0; i < listlevel.Count; i++) { if(i > XP && i < XP) { Debug.Log(i); indexNumber = i; } } }

Ok I have that but it doesnt return a value yet, am i missing something?

Just another implementation:

var result = new List<int>();
var number = 500;
do
{
    result.Add(number);
    number+= 150;
} while (number <= 2000000);
