C# way to add value in a List<T> at index

addition, c#, indexing, list, this

Solution

`List<T>.Insert`, perhaps?

But I'd suggest you probably just want to fetch/write - not insert:

public Multime<T> this[int index]
{
    get { return Multisets[index]; }
    set { Multisets[index] = value; }
}

Note that as of C# 3, there are simpler ways of writing those properties, btw:

public List<T> Multimea { get; set; }
public List<Multime<T>> Multisets { get; set; }

It's also not generally a good idea to actually expose composed collections directly - it means you have no control over what happens in those collections.

Problem

Is there any way you can add a value at a specific index? I try to do indexator and I have Lists. Is there any trick for making this this in this context :D ``` public class Multime<T> { private List<Multime<T>> multiSets; private List<T> multimea; ***public Multime<T> this[int index] { get { return this.Multisets.ElementAt(index); } set { this.Multisets.CopyTo(value,index); } }*** public List<Multime<T>> Multisets { get { return this.multiSets; } set { this.multiSets = value; } }//accesori Multimea de multimi public List<T> Multimea { get { return this.multimea; } set { this.multimea = value; } }//Accesori Multime ```
