    public DataTable ConvertToDataTable(IList data)
    {
        PropertyDescriptorCollection properties =
            TypeDescriptor.GetProperties(typeof(T));
    
        DataTable table = new DataTable();
    
        foreach (PropertyDescriptor prop in properties)
                table.Columns.Add(prop.Name, Nullable.GetUnderlyingType(prop.PropertyType) ?? prop.PropertyType);
    
        foreach (T item in data)
        {
            DataRow row = table.NewRow();
            foreach (PropertyDescriptor prop in properties)
            {
               row[prop.Name] = prop.GetValue(item) ?? DBNull.Value;
            }
            table.Rows.Add(row);
        }
        return table;
    }
