如何将datetime插入time(0)字段

Question

我正在做一个批量插入:

// Get the data into the DataTable
//dtData = GetData(...);

// Create an object of SqlBulkCopy
SqlBulkCopy objSBC = new SqlBulkCopy(connection);
// Specify the destination table
objSBC.BulkCopyTimeout = 0;
objSBC.BatchSize = 10000;
objSBC.DestinationTableName = "QuickLabDump";
// Write the data to the SQL Server

objSBC.WriteToServer(QuickLabDump);

我插入的数据表看起来像这样:

QuickLabDump = new DataTable();

QuickLabDump.Columns.Add("Time Collected", typeof(TimeSpan));
QuickLabDump.Columns.Add("Time Entered", typeof(TimeSpan));
QuickLabDump.Columns.Add("Time Completed", typeof(TimeSpan));
QuickLabDump.Columns.Add("Test Time", typeof(TimeSpan));

QuickLabDump.Columns.Add("Date Collected", typeof(DateTime));
QuickLabDump.Columns.Add("Date Entered", typeof(DateTime));
QuickLabDump.Columns.Add("Date Completed", typeof(DateTime));
QuickLabDump.Columns.Add("Test Date", typeof(DateTime));
......

当我从c#(上面的代码)运行批量插入时,我收到以下错误:

The given value of type DateTime from the data source cannot be converted to type time of the specified target column.

我认为问题是我插入typeof(DateTime)到sql server 2008表中time(0)

这是我插入的数据示例:

6:50:00 AM
6:50:00 AM
6:50:00 AM
10:36:00 AM
4:45:00 PM
7:39:00 PM

问题:如何正确定义数据表列,以便将上述时间值插入time(0)列中？

以下是时间(0)字段中数据库表中已存在的值:

14:57:00
14:58:00
14:58:00
14:57:00
10:49:00
13:31:00
14:02:00
14:13:00
14:20:00
14:56:00
15:00:00

这就是我将数据添加到DataTable:

 public DataTable dt;
        public ReadFileIntoDataTable(string inputfile)
        {
            using (GenericParserAdapter parser = new GenericParserAdapter())
            {
                parser.SetDataSource(inputfile);

                char[] delimiters = new char[] { ',' };
                parser.ColumnDelimiter = delimiters[0];
                parser.FirstRowHasHeader = true;
                //parser.SkipDataRows = 10;
                parser.MaxBufferSize = 4096;
                //parser.MaxRows = 500;
                parser.TextQualifier = '\"';

                dt = parser.GetDataTable();   


            }

Answer 1

用TimeSpan而不是DateTime.你可以得到一个TimeSpan 从一个DateTime使用DateTime.TimeOfDay.
