c# - issues customizing List into ListCustomMinIndexedForEach (stripped from irelevant implementations)
Answer
I tried to do my best to keep the title short but still informative.
I think I have succeeded with most of it
my problem For Now:(TLDR below)
I could not succeed implementing a public void method-member, nor an extension to Implement custom ForEach()
with index..
as Extension
public static ListWithCounter ForEach(this ListWithCounter Self, Action itm)//, ListWithCounter l = l.CurId)
{
for (int i = 0; i < Self.Count; i++)
{
Self.CurId = i;
itm(Self[i]);Self.CurId++;
}
return Self;
}
this is a small issue I guess, the objectives :
Create Customized List No Fancy Extra(Expensive) methods
add an elegant ForEach implementation
- optional tricks like out of the box
GetEnumValues/names
.To{ourCustomList}()
USAGE
in this example I am using an Enum
( names of Actions also used to present action items in console menu)
public enum ActSrptS { CreateMmfTfomFile_DoFormat, OpenExitMmfT, .... }
so I print it to console by unleashing the power of That small List class
//a struct ConsoleModifiers + ConsoleKey
ActScrptS aAction = ActScrptS._Start; Combination Comb = new Combination();
var actS = aAction._EnmGetValues();
var actSNms = aAction.EnumGetNamesToList().ForEach(Act =>
{
Console.WriteLine("[{0}]{1}", actS.CurId, Act);
});
Console.WriteLine("===============\r\n");
Console.WriteLine("please Select Action");
and it's simply using (TRYING without success for now..)
public static ListWithCounter EnumGetNamesToList(this Enum selfEnum)
{
return selfEnum.GetType().GetFields(BindingFlags.Static | BindingFlags.Public)
.Select(f=>f.Name).ToList();
//var values = Enum.GetNames(typeof(selfEnum)).ToList();
//return values;
//var values = Enum.GetValues(typeof(Environment.SpecialFolder)).Cast().ToList();
}
public static ListWithCounter _EnmGetValues(this Enum Self)
{
ListWithCounter enumerations = new ListWithCounter();
foreach (FieldInfo fieldInfo in Self.GetType().GetFields(
BindingFlags.Static | BindingFlags.Public))
{
enumerations.Add((Enum)fieldInfo.GetValue(Self));
}
return enumerations;
}
so I started with MSDN List.cs
and I tried to implement as less methods as possible
- leaving minimal important functionality
- altering Growth/Expand for -minimal copying so staring capacity is from say 10-50, multiplied by *4 on each limit...
