Question

I was curious if anyone had a good way to solving this problem efficiently. I currently have the following object.

Dictionary<int, Dictionary<double, CustomStruct>>

struct CustomStruct
{
    double value1;
    double value2;
    ...
}

Given that I know the ‘int’ I want to access, I need to know how to return the ‘double key’ for the dictionary that has the lowest sum of (value1 + value2). Any help would be greatly appreciated. I was trying to use Linq, but any method would be appreciated.

Answer 1

var result = dict[someInt].MinBy(kvp => kvp.Value.value1 + kvp.Value.value2).Key;

using the MinBy Extension Method from the awesome MoreLINQ project.
