Sql server 存储过程返回需要转换为CSV文件的临时表

我基本上有一个通过方法调用的存储过程：

Time_Tracker.BLL.ResultsManager.GetCSV(Convert.ToDateTime("2014-01-11"));

它返回8列数据，范围从25到150条记录

我需要能够将其转换为CSV文件到用户选择的路径。我可以将它作为数组Results[]TEST=newresults[25]放入我的代码中；并且已经验证了数据是否正确。我看到很多帖子都使用DataTable作为转换为CSV的源，但我不确定如何从调用存储过程的方法加载DataTable。DataGridView也是一样，也不知道如何将数据加载到DataGridView中

我还看到了使用SqlDataAdapter填充数据表的方法。由于我使用直接处理存储过程的方法，所以我不想每次都使用SqlDataAdapter并提供数据库配置信息

如果有人能帮我把它加载到DataTable或DataGridView中，我想我可以从那里找到答案

先谢谢你

只需定义一个数据表，并使用load命令将数据从读卡器移动到数据表

-- Code from msdn
SqlConnection sqlConnection1 = new SqlConnection("Your Connection String");
SqlCommand cmd = new SqlCommand();


cmd.CommandText = "StoredProcedureName";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Connection = sqlConnection1;

sqlConnection1.Open();

SqlDataReader reader = cmd.ExecuteReader();

-- This is my addition
DataTable dt = new DataTable();
dt.Load(reader);

sqlConnection1.Close();

这是来自MSDN的。我添加了两行来加载数据表

-- Code from msdn
SqlConnection sqlConnection1 = new SqlConnection("Your Connection String");
SqlCommand cmd = new SqlCommand();


cmd.CommandText = "StoredProcedureName";
cmd.CommandType = CommandType.StoredProcedure;
cmd.Connection = sqlConnection1;

sqlConnection1.Open();

SqlDataReader reader = cmd.ExecuteReader();

-- This is my addition
DataTable dt = new DataTable();
dt.Load(reader);

sqlConnection1.Close();

我还是不明白你想做什么。您可以通过编码创建数据表xml记录集

下面的代码可用于将数组转换为数据表。您需要做一些工作来添加详细信息

我希望这有帮助。如果没有，我仍然无法满足业务需求。

我已经解决了，请参见下文。我会将此标记为已解决，再次感谢您的帮助

       foreach (DataRow dr in dt.Rows)
        {
            for (int i = 0; i < iColCount; i++)
            {
              if (!Convert.IsDBNull(dr[i]))
                {
                    if (dr[i] is DateTime)
                    {
                        if (((DateTime)dr[i]).TimeOfDay.TotalSeconds == 0) // Time Since Midnight (in Seconds)
                        {
                            sw.Write(((DateTime)dr[i]).ToString("yyyy-MM-dd"));
                        }
                    }

                    else
                    {
                        sw.Write(dr[i].ToString());
                    }
                }

                if (i < iColCount - 1) sw.Write(",");
            }
            sw.Write(sw.NewLine);
        }

除了将数据从数据库传递到csv文件之外，您还需要处理程序中的数据吗？数据中可能有空值吗？数据中可能有逗号吗？我没有看到将帖子标记为已回复的链接。有人能把这根线收起来吗？谢谢
