我試圖自動填充每月使用asp.net的報告＃

Question

我的任務是，每個月，藥物表中的數量列將更新到當前月份的報告表中的列。我想在不使用任務調度程序的情況下執行此操作。我在線研究了線程和計時器。但是，我不確定它是否可以工作，因爲線程將每月自動更新同一列。正如你所看到的，我需要每個月更新不同的列。

這裏是我的代碼：

DateTime today = DateTime.Today; 
DateTime firstDay = new DateTime(today.Year, today.Month, 1); 
if (today == firstDay) 
{ 
    while (true) 
    { 
     string sql1 = "SELECT quantity FROM medicine"; 
     DataSet ds = DBMgr.GetDataSet(sql1); 
     int quantity = int.Parse(ds.Tables[0].Rows[0]["quantity"].ToString()); 
     string month = DateTime.Now.ToString("MMMM"); 

    if (month.Equals("January")) 
    { 
     string sql = "UPDATE report SET Jan = '{0}'"; 
     DBMgr.ExecuteSQL(sql, quantity); 
    } 
    if (month.Equals("February")) 
    { 
     string sql = "UPDATE report SET Feb = '{0}'"; 
     DBMgr.ExecuteSQL(sql, quantity); 
    } 
    if (month.Equals("March")) 
    { 
     string sql = "UPDATE report SET Mar = '{0}'"; 
     DBMgr.ExecuteSQL(sql, quantity); 
    } 
    if (month.Equals("April")) 
    { 
     string sql = "UPDATE report SET Apr = '{0}'"; 
     DBMgr.ExecuteSQL(sql, quantity); 

    } 
    if (month.Equals("May")) 
    { 
     string sql = "UPDATE report SET May = '{0}'"; 
     DBMgr.ExecuteSQL(sql, quantity); 
    } 
    if (month.Equals("June")) 
    { 
     string sql = "UPDATE report SET June = '{0}'"; 
     DBMgr.ExecuteSQL(sql, quantity); 
    } 
    if (month.Equals("July")) 
    { 
     string sql = "UPDATE report SET July = '{0}'"; 
     DBMgr.ExecuteSQL(sql, quantity); 
    } 
    if (month.Equals("August")) 
    { 
     string sql = "UPDATE report SET Aug = '{0}'"; 
     DBMgr.ExecuteSQL(sql, quantity); 
    } 
    if (month.Equals("September")) 
    { 
     string sql = "UPDATE report SET Sep = '{0}'"; 
     DBMgr.ExecuteSQL(sql, quantity); 
    } 
    if (month.Equals("October")) 
    { 
     string sql = "UPDATE report SET Oct = '{0}'"; 
     DBMgr.ExecuteSQL(sql, quantity); 
    } 
    if (month.Equals("November")) 
    { 
     string sql = "UPDATE report SET Nov = '{0}'"; 
     DBMgr.ExecuteSQL(sql, quantity); 
    } 
    if (month.Equals("December")) 
    { 
     string sql = "UPDATE report SET Dec = '{0}'"; 
     DBMgr.ExecuteSQL(sql, quantity); 
    } 
    else 
    { 
     LblMsg.Text = "An Error Occurred"; 
    } 
} 

當月的列並沒有被更新的。提前致謝！

不確定計時器是否適合您的情況。很可能它沒有被調用，因爲當前池中有一個定時器被停止，並且沒有其他請求來喚醒池並重新啓動定時器。閱讀關於回收的應用程序池和default settings
