    @{
    Layout = null;
    }

    <head><title> Demo</title></head>

    <body>
    <h1> People</h1>

    @IEnumerator EmpEnumerator = Model.GetEnumerator();


    @EmpEnumerator.Reset();
    @while (EmpEnumerator.MoveNext())

    Hi,

    As you are using IEnumerable<DemoApp.Person>, GetEnumerator returns IEnumerator<DemoApp.Person>. IEnumerable would return IEnumerable.

    Not sure what is the point of coding explicitly what foreach does for you behind the scene?

    I you simply want to display the people list here, 

    First make sure that in your controller  -> action  method returns  IEnumerable<DemoApp.Person> to View and its right type that is expected as model in view.

    Second you can print this in for each by getting the Model and  

    //Assume that person class have a property "Name"
    
    @foreach (var p in Model)
    {
       <li>@p.Name</li>
    }

    Hi siddangoud,

    According to your modified content, these cannot be presented in the view page.

    The tutorial you provided in the link is the simplest and most common way of writing.

    Why would you use custom variables for display?

    The reference link is the best way, you don't need to complicate the content.

    Best Regards,

    YongQing.
