Winforms - 创建动态表的问题

Question

我有一个Windows窗体应用程序，其中我有多个表的视图。通过按对象的属性设置列的名称，然后将它们添加到数据集，可以动态构建表。还为每个表添加了一个空行。我遇到的问题是，在用于创建这些表的9个对象中，有2个表未设置任何列或空行。

我已经查看了调试，并将获取列的对象属性与没有列的对象进行了比较，并且无法解释问题所在。以前有没有人遇到过这个问题？如果是这样，问题是什么？

这是我的代码，请告诉我是否还需要其他信息：

protected override DataSet GetDefaultFilterTypes()
    {
        return DataSetUtility.ToDataSet(new List<Type> { typeof(Counterparty), typeof(Address), typeof(Contact),
            typeof(Customer), typeof(Broker), typeof(ExchangeBroker), typeof(ExchangeBrokerAccount), typeof(Supplier), typeof(SupplierTerminalPriceMapping) });
    }


public static DataSet ToDataSet(IList<Type> list)
    {
        DataSet ds = new DataSet();

        foreach (Type item in list)
        {
            DataTable ta = new DataTable(item.ToString());
            ds.Tables.Add(ta);

            //add a column to table for each public property on T
            foreach (var propInfo in item.GetProperties())
            {
                Type colType = Nullable.GetUnderlyingType(propInfo.PropertyType) ?? propInfo.PropertyType;
                ta.Columns.Add(propInfo.Name, colType);
            }

            DataRow row = ta.NewRow();

            foreach (var propInfo in item.GetProperties())
            {
                row[propInfo.Name] = DBNull.Value;
            }

            ta.Rows.Add(row);
        }

        return ds;
    }

这里是ExchangeBroker和Supplier的类定义 - 没有获取列的对象：
