Edit multiple instances of models asp.net mvc

Question

I want to edit multiple (say 4) instance of my model Restriction:

public int RestrictionID { get; set; }
public string portefeuille { get; set; }

I try to do this in my view:

@model IEnumerable<Management.Models.Restriction>
@for ( int i= 0; i < 4; i++)
{
    @Html.EditorFor(_ => Model.[i].portefeuille)
}

But I have an error that I can't use indexation on type IEnumerable.

Can somebody help me to solve this problem?

Your model needs to be IList, not IEnumerable

try below code using ILIst because in IEnumerable we cant use indexation ..for using indexation you should go for IList + remove extra "." between Model and [i] :-

 @model ILIst <Management.Models.Restriction>
 @for ( int i= 0; i < 4; i++)
{
   @Html.EditorFor(_ => Model[i].portefeuille)
 }

For more information have a look here :-

Cannot apply indexing with [] to an expression of type 'System.Collections.Generic.IEnumerable<>

You could also use linq instead of indexing:

for(int i = 0; i < 4; i++)
{
    @Html.EditorFor(m => m.Skip(i).Take(1).First().portefeuille)
}
