Finding Unique Values and Summing them from an Array Using LINQ

Assume I have an array ArrayVariable = New System.Int32(){1,1,2,2,3,4,4,5}
And I wish to sum the distinct values into Sum.

I know how to find distinct values, but I am not able to sum them

Any idea?

Thanks in Advance!

Check as below

Use ArrayVariable.Distinct().ToArray.Sum(Function (r) Double.Parse(r.ToString))

Mark as solution if this help you

Thanks

Brilliant!
The highlighted operation in
ArrayVariable.Distinct.ToArray.Sum(Function(s) s)
didn’t show up in intellisense, so I thought it wouldnt work.
Thank you once again!
