将列名和行从 DbDataReader 获取到列表

Question

我正在尝试执行存储过程。存储过程名称是动态给出的。基本上它用于报告套件。当用户select report name from dropdown时，它会将sp的name传递给action result里面returns一组数据，我设法从sp中获取结果到List中数据列表。现在我正在尝试获取要添加到列表数据列表中的列名。任何帮助将不胜感激

var cmd = _ctx.Database.GetDbConnection().CreateCommand();

cmd.CommandText = uspName;
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter("@inparam_Fromdate", DateTime.Now.AddDays(1));
cmd.Parameters.Add(new SqlParameter("@inparam_Todate", "DateTime.Now.AddDays(2)));

cmd.Connection.Open();

using (var reader = cmd.ExecuteReader())
{
    List<string[]> dataList = new List<string[]>();

    while (reader.Read())
    {
        string[] tempRow = new string[reader.FieldCount];
        for (var i = 0; i < reader.FieldCount; i++)
        {
            tempRow[i] = Convert.ToString(reader.GetValue(i));
        }

        dataList.Add(tempRow);
    }


}

cmd.CommandText = uspName;
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.Add(new SqlParameter("@inparam_Fromdate", "2019-05-05"));
cmd.Parameters.Add(new SqlParameter("@inparam_Todate", "2019-05-22"));

cmd.Connection.Open();

using (var reader = cmd.ExecuteReader())
{
    var dataList = new List<string[]>();

    var tempCol = new string[reader.FieldCount];
    for (var i = 0; i < reader.FieldCount; i++)
    {
        tempCol[i] = reader.GetName(i);

    }
    dataList.Add(tempCol);


    while (reader.Read())
    {
        var tempRow = new string[reader.FieldCount];
        for (var i = 0; i < reader.FieldCount; i++)
        {
            tempRow[i] = Convert.ToString(reader.GetValue(i));
        }

        dataList.Add(tempRow);
    }

}
