Excel（字符串）到數據庫（TimeSpan）

Question

我遇到了一個問題，我無法將Excel的開始時間和結束時間保存到數據庫中。對於Excel，時間類型爲「字符串」，但對於數據庫，時間類型爲「時間」。有什麼方法可以將Excel時間保存到數據庫中。

這是我的代碼，它將數據保存到數據庫中，但它只保存名稱和日期，但不保存時間。任何幫助將不勝感激。

private void btnSave_Click(object sender, EventArgs e) 
    { 
     try 
     { 

      foreach (DataRow dr in dt.Rows) 
      { 
       string strEmployee = dr["Employee Name"].ToString(); 
       //store data into employeeshift DB 
       using (satsEntities db = new satsEntities()) 
       { 
        ufi empShift; 
        IList<employeeschedule> employeeList = dict[strEmployee]; 

        foreach (employeeschedule es in employeeList) 
        { 
         empShift = new ufi(); 
         TimeSpan a = new TimeSpan(Convert.ToInt32(es.startTime.Substring(0,2), Convert.ToInt32(es.startTime.Substring(2,2)))); 
         TimeSpan b = new TimeSpan(Convert.ToInt32(es.endTime.Substring(0,2), Convert.ToInt32(es.endTime.Substring(2,2)))); 
         empShift.UFISDate = es.day; 
         empShift.EmployeeName = strEmployee; 
         empShift.startTime = a; 
         empShift.endTime = b; 
         db.ufis.AddObject(empShift); 
        } 
        db.SaveChanges(); 
       } 
      } 
      MessageBox.Show("Data is stored to database successfully."); 
     } 
     catch (Exception ex) 
     { 
      //showMessage("UNABLE to store to database successfully."); 
      //show error 
     } 
    } 

由於我的信譽低，我無法發佈自己的答案。畢竟，這是我的答案，讓我的代碼工作。

private void btnSave_Click(object sender, EventArgs e) 
    { 
      foreach (DataRow dr in dt.Rows) 
      { 
       string strEmployee = dr["Employee Name"].ToString(); 
       //store data into employeeshift DB 
       using (satsEntities db = new satsEntities()) 
       { 
        ufi empShift; 
        IList<employeeschedule> employeeList = dict[strEmployee]; 

        foreach (employeeschedule es in employeeList) 
        { 
         empShift = new ufi(); 
         TimeSpan a = new TimeSpan(Convert.ToInt32(es.startTime.Substring(0,2)), Convert.ToInt32(es.startTime.Substring(2,2)), 0); 
         TimeSpan b = new TimeSpan(Convert.ToInt32(es.endTime.Substring(0,2)), Convert.ToInt32(es.endTime.Substring(2,2)), 0); 
         empShift.UFISDate = es.day; 
         empShift.EmployeeName = strEmployee; 
         empShift.startTime = a; 
         empShift.endTime = b; 
         db.ufis.AddObject(empShift); 
         db.SaveChanges(); 
        } 

       } 
      } 
      MessageBox.Show("Data is stored to database successfully."); 
    }

這能否幫助

 string test = "1234"; 
     string startTime = test.Substring(0, 2); 
     string Endtime = test.Substring(test.Length - 2); 
     string NewTime = startTime + ":" + Endtime;
