Hello Experts!

I have a Dictionary storing data as such: Dictionary<string, IList<T>>();

I am trying to select the total number of values without having to use nested foreach loops.

I found this using LinQ,

myRowCnt = deptToEmp.Skip(1).Sum(x => x.Value);

Open in new window


But because value is a Collection, this will not work. I was trying to modify it myself, but I am not familiar with LinQ.

Any help would be greatly appreciated!

double total = deptToEmp.Values.Sum(x => x.Sum());

Or you might modify your original:

myRowCnt = deptToEmp.Skip(1).Sum(x => x.Value.Sum());
