C# 如何在读取带有三个select语句的存储过程时创建列表c

我正在尝试创建一个从存储过程中的列中获取的信息列表。我在存储过程中运行了三条select语句。返回一行6列。另外两个返回3列8行

例如：

A B C D E F//select one
one row of results
G H I//select two
8 rows of results
G H I//select three
8 rows of results

问题是我得到了一个索引超出范围的异常，我给列表赋值。我猜这是因为它返回的两个语句，因为它们都说FaultStart？我想把我的阅读器限制在前8行，但是我需要的最后8行呢。如何获得具有相同行名称的两个select语句的返回

SqlCommand cmd = new SqlCommand("L_getDownTimeByLine", conn);
cmd.Parameters.Add("@startTime", SqlDbType.DateTime, 30).Value = RadDateTimePicker2.SelectedDate;
cmd.Parameters.Add("@endTime", SqlDbType.DateTime, 30).Value = RadDateTimePicker3.SelectedDate;
cmd.Parameters.Add("@line", SqlDbType.Int, 2).Value = 1;
cmd.CommandType = CommandType.StoredProcedure;
conn.Open();

List<string> test = new List<string>();

SqlDataAdapter da = new SqlDataAdapter(cmd);

SqlDataReader dr = cmd.ExecuteReader();

while (dr.Read())
{
    Line1ADT = dr["A Line Down Time"].ToString();
    Line1ADP = dr["A Line Percentage"].ToString();
    Line1BDT = dr["B Line Down Time"].ToString();
    Line1BDP = dr["B Line Percentage"].ToString();
    Line1TDT = dr["Total Down Time"].ToString();
    Line1TDP = dr["Total Percentage"].ToString();
    test.Add((dr["FaultStart"].ToString()));//here is where my problem is.

}
dr.Close();

你能在你的帖子中添加exception.Message或stack trace吗？我有一些关于出错原因的想法，但是如果没有看到你返回的sql，推测就没有意义了。你能发布你的狂欢吗？或者至少是正在进行的相关sqlreturned@Brandon“是的，等等。”布兰登追查。是的，我从来没有试过做你在这里做的事，所以这是一个危险信号。这可能更适合于两种不同的存储过程，一种使用临时表，另一种使用linedowntime。至少，将这些列放入一个union all可以解决您的问题，因为您将被迫为所有5列创建一个值。
