Use case: Storing a collection of Images (e.g. array on Ints)
When using GetValue the type is returned rather than the items.

I think this is caused by having the Umbraco Core Property Value Converters installed.

It took me a while to figure it out, so I thought I'd share it here too.

Solution either type it correctly for the thing you are working with, or use the GetRawValue method.

Get Value

foreach (var item in Model.Items.Where(x => x != null))
{
    var test = item.GetValue<string>("images");
    @test // outputs: system.int32[]
}

GetValue IEnum

foreach (var item in Model.Items.Where(x => x != null))
{
    var test = item.GetValue<IEnumerable<int>>("images");
    foreach (var x in test)
    {
        @x // outputs: 112711261128
    }
}

GetRawValue

foreach (var item in Model.Items.Where(x => x != null))
{
    var test = item.GetRawValue("images");
    @test // outputs: 1127,1126,1128
}
