Populate a ListView with Strings

I'm a bit new to ASP.NET, so bear with me. I came across this solution which would allow me to add an array of strings to a ListView as a row of data. However, I'm not sure on the proper way to set it up. In just trying this solution with a ListView I dropped onto my website, I'm told that new ListViewItem() requires a parameter of type ListViewItemType. The sample solution doesn't provide that, so is it different in ASP.NET?

So the main question I'm asking is: If I have an array of strings, how can I add that to a ListView as a row of data in ASP.NET?

EDIT: I'd like to make sure I'm asking for the right control. I was under the impression a ListView was something like this (but in ASP.NET), but what I'm getting so far is not. It's just a line of text.

If you want to display like in the example, you want to use GridView instead of ListView.

String collection is not enough to display in multiple columns. You need a collection of objects.

Screen Shot (top is ListView, bottom is GridView)

enter image description here

Sample Code

<asp:ListView runat="server" ID="ListView1">
    <ItemTemplate>
        <%# Eval("Name") %>, 
        <%# Eval("Email") %>, 
        <%# Eval("Phone") %><br />
    </ItemTemplate>
</asp:ListView>
<br/>
<asp:GridView ID="GridView1" AutoGenerateColumns="True" runat="server" />

public class User
{
    public string Name { get; set; }
    public string Email { get; set; }
    public string Phone { get; set; }
}

protected void Page_Load(object sender, EventArgs e)
{
    var collections = new List<User>
        {
            new User {Name = "Jon Doe", Email = "[email protected]", Phone = "123-123-1234"},
            new User {Name = "Marry Doe", Email = "[email protected]", Phone = "456-456-4567"},
            new User {Name = "Eric Newton", Email = "[email protected]", Phone = "789-789-7890"},
        };

    ListView1.DataSource = collections;
    ListView1.DataBind();

    GridView1.DataSource = collections;
    GridView1.DataBind();
}

You can convert your array to list with ToList operator

c#

lv.DataSource = yourArray.ToList();
lv.DataBind();

asp.net

<asp:ListView ID="lv" runat="server">

        <ItemTemplate>
            <asp:Label ID="lbl" runat="server" Text='<%# Container.DataItem %>'/>
        </ItemTemplate>

</asp:ListView>
