N your collection is in the type of IEnumerable. So you can Convert it in to Datatable by using the below method

C#

public static DataTable ToDataTable<t>(this List<t> items)
{
    var tb = new DataTable(typeof(T).Name);

    PropertyInfo[] props = typeof(T).GetProperties(BindingFlags.Public | BindingFlags.Instance);

    foreach(var prop in props)
    {
        tb.Columns.Add(prop.Name, prop.PropertyType);
    }

     foreach (var item in items)
    {
       var values = new object[props.Length];
        for (var i=0; i<props.length;>        {
            values[i] = props[i].GetValue(item, null);
        }

        tb.Rows.Add(values);
    }

    return tb;
}

Hope this helps

DataTable dtRegistration = new DataTable();

oEntities BusinessObjects = new 0Entities();

protected void Page_Load(object sender, EventArgs e)
{
var getcountries = BusinessObjects.GetCountry();

C#

foreach (var item in RegionCount)
{
                    count = item.region;
}

}
