Is that possible to divide all elements in C# double list to that double list elements sum (which makes total = 1)

Question

Imagine a doube list like the follow ``` List lstDouble=new List{4,6,2,7,1,1}; ``` So what i want is dividing all elements in this list to sum of the elements(21). So the list becomes after dividing : ``` lstDouble = {4/21,6/21,2/21,7/21,1/21,1/21} ``` Which would mean that the new sum of the elements = 1 I can do that via iteration etc but i wonder are there any short way since Matlab has. And my assistant professor keep telling me that learn Matlab and use it but i don't want :D I love C# Thank you. C# 4.0 WPF application

Accepted Answer

var sum = lstDouble.Sum();
var result = lstDouble.Select(d => d / sum);
```
