如何從datetimepicker獲取值

Question

我試圖從datetimepicker中選擇日期和時間，並從數據庫中獲取值，但它不起作用。任何人都可以幫助我。

這是我的命令：

OleDbCommand com1 = new OleDbCommand("select * from tblConsumption where date between #"dateTimePicker1.Value.ToShortDateString"# and #"dateTimePicker2.Value.ToShortDateString"#",con); 

Answer 1

我想你想是這樣的：

string myCommand = 
    "select * from tblConsumption "+ 
    "where date between #"+dateTimePicker1.Value.ToShortDateString()+"# and "+ 
    "#"+dateTimePicker2.Value.ToShortDateString()+"#"; 

OleDbCommand com1 = new OleDbCommand(myCommand,con); 

如果這不起作用，你可以把一個斷點字符串賦值後，看看是什麼調試器中的sql語法錯誤。

確保您的代碼編譯！
