How to Read TagHelper property text value?

Question

i want to get string text of assigned property name? for example: I have a TagHelper:

public class CustomControl: TagHelper
{
[HtmlAttributeName("Items")]
public IEnumerable<object> DataItems { get; set; }

public async override Task ProcessAsync(TagHelperContext context, TagHelperOutput output)
{
   string stringText=datatitems.GetType()??? //it should result "listDataBC"
}

then used on any page :

<customcontrol Items="listDataBC"/>

Thank you

You could use the ModelExpression as parameter and use "@listDataBC" to get the name and values.
CustomControl.cs

    public class CustomControl : TagHelper
    {
        [HtmlAttributeName("Items")]
        public ModelExpression expression { get; set; }

        public async override Task ProcessAsync(TagHelperContext context, TagHelperOutput output)
        {
        
            var name = expression.Name;
            var value = expression.Model; 
        }
    }

Index.cshtml

@{
    var listDataBC = new List<object>()
    {
        new {Name="tom"},
        new {Name="kite"}
    };
}
<custom-control Items="@listDataBC"></custom-control>
