Looking to see if there is a simpler way to achieve this. I would love if I could keep the return as a one-line LINQ expression. I want to grab the total number of hints used, which can be more than one.
public int hintsUsed
{
get
{
int i = 0;
questions.ForEach(q => i += q.hintsUsed);
return i;
}
}
You can use the Sum function
public int HintsUsed => questions.Sum(q => q.hintsUsed);
By using an expression bodied member (since C# 6.0), you can even get rid of the get and the return keywords plus a few braces.
The code above is equivalent to
public int HintsUsed
{
get
{
return questions.Sum(q => q.hintsUsed);
}
}
Most of the LINQ-to-Objects functionality is provided by the Enumerable Class.
