【C#】将数据库读出的数据转换为DataTable类型集合

return View(ConverDataReaderToDataTable(reader));

// 静态方法
public static DataTable ConverDataReaderToDataTable(IDataReader reader)
        {
            // 检查外部传入的参数
            if (null == reader)
                return null;

            // 实例化一个DataTable
            DataTable dataTable = new DataTable();
            dataTable.Locale = System.Globalization.CultureInfo.InvariantCulture;

            int fieldCount = reader.FieldCount;

            // 在表中创建字段
            for (int counter = 0; counter < fieldCount; counter++)
            {
                dataTable.Columns.Add(reader.GetName(counter), reader.GetFieldType(counter));
            }

            dataTable.BeginLoadData();

            object[] values = new object[fieldCount];
            while (reader.Read())
            {
                // 添加行
                reader.GetValues(values);
                dataTable.LoadDataRow(values, true);
            }

            // 完成转换并返回
            dataTable.EndLoadData();
            return dataTable;
        }

html显示：

@model System.Data.DataTable
<table>
            <tr>
                @for (int i = 0; i < Model.Columns.Count; i++)
                {
                    <td>@Model.Columns[i].ColumnName</td>
                }
            </tr>
            @for (int i = 0; i < Model.Rows.Count; i++)
            {
                <tr>
                    @for(int j = 0; j < Model.Rows[i].ItemArray.Count(); j++)
                    {
                        <td>@Model.Rows[i].ItemArray[j]</td>
