Need help in writing a program that calculates the sum of integers in a given range and are also divisible by the given integer?

C#

I have to write a program that calculates the sum of all the integers in a given range and is also evenly divisible by a given integer. The user supplies the beginning, ending and the divisor integer.

I created two classes for this- the program class that accepts the inputs from the user and the summation class that does all the calculations.

I can't figure out how to write the code for the method in the summation class! any help would be appreciated!

Thanks! :)

Edit 1=

Thanks for the help guys! It's not homework. It's like a practice project that I'm doing for a class that I'll take next semester.

I know how to set up the loop for predefined values, but I can't figure out how to work the loop for user acceptable values.

Here's what I have so far:

The program class:

Summation

sum = new Summation();

Console.WriteLine("Please enter the lower limit of the integer range.");
sum.LowerLimit = Convert.ToInt16(Console.ReadLine());

Console.WriteLine("Please enter the upper limit of the integer range.");
sum.UpperLimit = Convert.ToInt16(Console.ReadLine());

Console.WriteLine("Please enter the divisor(the number that is to divide evenly into the values in this range).");
sum.Divisor = Convert.ToInt16(Console.ReadLine());

sum.Summation();

Console.WriteLine("The range of numbers that divide into your chose divisor is:{0}.", sum.Sum);

The summation class:

class

Summation
{
public int lowerLimit, upperLimit, divisor, sum;
public int LowerLimit
{
get { return lowerLimit; }
set { lowerLimit = value; }
}

public int UpperLimit
{
get { return upperLimit; }
set { upperLimit = value; }
}

public int Divisor
{
get { return divisor; }
set { divisor = value; }
}
public int Sum
{
get { return sum; }
set { sum = value; }
}

private float restart;

public float Restart
{
get { return restart; }
set { restart = value; }
}

int Sum = 0;        
        for (int i = LowerLimit; i <= UpperLimit; i++)
        {
            Sum = Sum + i;
        }

EDIT 2 :

I tried putting this code in (attached below) but it doesn't work. :/ I get several errors. I just can't figure out this piece of code. Tried everything Griff suggested too. Anything else that can help me? I will forever be greatful for any help!

  int Sum = 0;        
    
    for (int i = lowerLimit; i <= upperLimit; i++)
{
    if(i % divisor == 0)
    Sum = Sum + i;
}
    return Sum;
