public static DataTable ToDataTable<T>(this IList<T> data)

PropertyDescriptorCollection properties = TypeDescriptor.GetProperties(typeof(T));
DataTable dt = new DataTable();
for (int i = 0; i < properties.Count; i++)
{
PropertyDescriptor property = properties[i];
dt.Columns.Add(property.Name, property.PropertyType);
}
object[] values = new object[properties.Count];
foreach (T item in data)
{
for (int i = 0; i < values.Length; i++)
