Question

I am working only with integers and want to create a new instance of Fraction. I receive the error that I “Cannot implicitly convert type. ‘Fractions.Fraction’ to ‘int'”. The problem has to do with creating the new instance in this specific method. I need to return all three values from the method back to the class.

I have stepped through the code with the debugger and verified that the values are getting changed correctly. I am just unable to get them to return correctly. The error is on the last line of the reduce method. Still somewhat new to C# and would appreciate any suggestions.

public static int Reduce(int wholeNum, int numer, int denomi)
{
    int reduceWhole = (int)wholeNum;
    while(numer > denomi)
    {
        numer -= denomi;
        reduceWhole += 1;
    }
    while (denomi % numer == 0)
    {
        int factor =  (int)denomi/numer;
        numer = 1;
        denomi = factor;
    }
    return new Fraction(reduceWhole, numer, denomi);

}

Answer 1

Then simply change the signature of the method to return Fraction instead of int:

public static Fraction Reduce(int wholeNum, int numer, int denomi)
{
    // ....
    return new Fraction(reduceWhole, numer, denomi);
}
