Can an array of decimal values be assigned to a List of integers

Question

Is is possible to assign an array of decimal values to a list of integers? Let's say I have an array like decimal[] decemalNumbers and a list of integers like List intNumbers. So can I do the assignment like intNumbers = decemalNumbers.ToList()?

How Can I do an explicit conversion? Is it possible?

Only if you cast your `decimal` to an `int`; however you will loose your decimal places. — Essigwurst, Mar 12 '18 at 06:14
Use something like `intNumbers = decemalNumbers.Select(c => (int) c).ToList()` — Evk, Mar 12 '18 at 06:23
decimal[] decimalNumbers = new decimal[3]; decimalNumbers[0] = 454545.54M; decimalNumbers[1] = 454556.23M; decimalNumbers[2] = 454556.89M; List bagTagResult = decimalNumbers.Select(c => (int)c).ToList(); foreach (var item in bagTagResult) { Console.WriteLine(item); } — Ash18, Mar 12 '18 at 06:41

A simple LINQ solution:

decimal[] decimalNumbers = {1.11m,5.22m,3.25m,4.66m,9.13m};
List<int> integerNumbers = decimalNumbers.Select(x => Convert.ToInt32(x)).ToList();

Output:

integerNumbers[0]=1
integerNumbers[1]=5
integerNumbers[2]=3
integerNumbers[3]=5
integerNumbers[4]=9

try like this , to convert it to int

// obj is decimal array or list
IEnumerable<int> result = obj.select(d=> decimal.ToInt32(d));

Using `Cast` on decimal[] will result in an InvalidCastException when you start iterating. You have to use an explicit cast such as in `Select(d => (int)d)`. For an explanation why Cast does not work see [this answer](https://stackoverflow.com/questions/445471/puzzling-enumerable-cast-invalidcastexception). – Mike Zboray Mar 12 '18 at 06:18
@mikez - let me try at my end ...because cast is ment for casing value – Pranay Rana Mar 12 '18 at 06:19
@PranayRana `Cast` first boxes the value to `object`, before casting it, which then causes the `InvalidCastException`. – Dirk Mar 12 '18 at 06:25
