Get a distinct list of ids from IEnumerable<T>
I have an IEnumerable that I want to get all the distinct MaterialIDs. I have code that is working but I was wondering if there is a better way possible using LINQ. Here's the code I have:
private IEnumerable<int> GetDistinctMaterialIDs(IEnumerable<TankReading> tankReadings)
{
var distinctMaterialIDs = new List<int>();
foreach (var tankReading in tankReadings)
{
if (!distinctMaterialIDs.Contains(tankReading.MaterialID))
{
distinctMaterialIDs.Add(tankReadi开发者_如何学编程ng.MaterialID);
}
}
return distinctMaterialIDs;
}
Any help would be appreciated as I am learning how LINQ can help me.
tankReadings.Select(o => o.MaterialID).Distinct();
