SqlBulkCopy時間數據類型問題

Question

如何將時間批量複製到SQL Server數據庫表中？

例如我導入Excel片到我的應用，並且字段中的一個是Start Time和被映射到它的數據是10:30:00但是當它導入它到表它顯示30/12/1899 10:30:00。我怎樣才能擺脫日期部分？

我試過改變數據庫中的格式，至Time，varchar，DateTime但都一樣。

string conString = string.Empty; 
string extension = Path.GetExtension(FileUpload1.PostedFile.FileName); 

switch (extension) 
{ 
    case ".xls": //Excel 97-03 
     conString = ConfigurationManager.ConnectionStrings["Excel03ConString"].ConnectionString; 
     break; 

    case ".xlsx": //Excel 07 or higher 
     conString = ConfigurationManager.ConnectionStrings["Excel07+ConString"].ConnectionString; 
     break; 
} 

conString = string.Format(conString, excelPath); 

using (OleDbConnection excel_con = new OleDbConnection(conString)) 
{ 
    excel_con.Open(); 
    string sheet1 = excel_con.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null).Rows[0]["TABLE_NAME"].ToString(); 

    DataTable dtExcelData = new DataTable(); 

    //It is recommended as otherwise the data will be considered as String by default. 
    dtExcelData.Columns.AddRange(new DataColumn[18] { 
     new DataColumn("Name of Staff", typeof(string)), 
     new DataColumn("Host Key of Staff", typeof(int)), 
     new DataColumn("Name of Department", typeof(string)), 
     new DataColumn("Description of Preferred Zone of Staff", typeof(string)), 
     new DataColumn("User Text 2 of Staff", typeof(string)), 
     new DataColumn("Name of Programmes of Study of Module", typeof(string)), 
     new DataColumn("Description of Programmes of Study of Module", typeof(string)), 
     new DataColumn("Host Key of Locations", typeof(string)), 
     new DataColumn("Host Key of Module", typeof(string)), 
     new DataColumn("Description of Module", typeof(string)), 
     new DataColumn("Name", typeof(string)), 
     new DataColumn("Scheduled Start Date", typeof(string)), 
     new DataColumn("Teaching week pattern of Scheduled Activities as end date", typeof(string)), 
     new DataColumn("Section ID", typeof(string)), 
     new DataColumn("Description of Type", typeof(string)), 
     new DataColumn("Scheduled Start as day name", typeof(string)), 
     new DataColumn("Scheduled Start as start time", typeof(string)), 
     new DataColumn("Scheduled Finish as end time", typeof(string)), 
    }); 

    using (OleDbDataAdapter oda = new OleDbDataAdapter("SELECT * FROM [" + sheet1 + "]", excel_con)) 
    { 
     oda.Fill(dtExcelData); 
    } 

    excel_con.Close(); 

    string consString = ConfigurationManager.ConnectionStrings["PayrollPlusConnectionString"].ConnectionString; 

    using (SqlConnection con = new SqlConnection(consString)) 
    { 
     using (SqlBulkCopy sqlBulkCopy = new SqlBulkCopy(con)) 
     { 
      //Set the database table name 
      sqlBulkCopy.DestinationTableName = "dbo.Data"; 

      // Map the Excel columns with that of the database table 
      sqlBulkCopy.ColumnMappings.Add("Name of Staff", "NameOfStaff"); 
      sqlBulkCopy.ColumnMappings.Add("Host Key of Staff", "HostKey"); 
      sqlBulkCopy.ColumnMappings.Add("Name of Department", "Department"); 
      sqlBulkCopy.ColumnMappings.Add("Description of Preferred Zone of Staff", "Campus"); 
      sqlBulkCopy.ColumnMappings.Add("User Text 2 of Staff", "Grade"); 
      sqlBulkCopy.ColumnMappings.Add("Name of Programmes of Study of Module", "AOS"); 
      sqlBulkCopy.ColumnMappings.Add("Description of Programmes of Study of Module", "AOSDescription"); 
      sqlBulkCopy.ColumnMappings.Add("Host Key of Locations", "Room"); 
      sqlBulkCopy.ColumnMappings.Add("Host Key of Module", "ModuleAOS"); 
      sqlBulkCopy.ColumnMappings.Add("Description of Module", "ModuleDescription"); 
      sqlBulkCopy.ColumnMappings.Add("Name", "Activity"); 
      sqlBulkCopy.ColumnMappings.Add("Scheduled Start Date", "StartDate"); 
      sqlBulkCopy.ColumnMappings.Add("Teaching week pattern of Scheduled Activities as end date", "EndDate"); 
      sqlBulkCopy.ColumnMappings.Add("Section ID", "SectionID"); 
      sqlBulkCopy.ColumnMappings.Add("Description of Type", "Type"); 
      sqlBulkCopy.ColumnMappings.Add("Scheduled Start as day name", "Day"); 
      sqlBulkCopy.ColumnMappings.Add("Scheduled Start as start time", "StartTime"); 
      sqlBulkCopy.ColumnMappings.Add("Scheduled Finish as end time", "EndTime"); 

      con.Open(); 
      sqlBulkCopy.WriteToServer(dtExcelData); 
      con.Close(); 

      lblStatus.Text = "Upload Successful"; 
     } 
    } 
}

嘗試從datetime轉換時間如下。

convert(Time, getdate())
