店鋪ID的數據庫

我在這裏有一個小問題，我有以下的主表店鋪ID的數據庫

M_employee

EMPID Name 

1  abc 
2  xyz

M_Division

DIVID EMPID DIVISON 

1  2  arts 
2  1  science

M_Designation

DESGID EMPID Designation 

1   2  Teacher 
2   1  Scientist

和基於ID在主表中的存在我檢索一個表單中的標籤上的幾個字段....我想要做的是當我將這些表格的值存儲在一個新表中我只想要存儲的id而不是正在顯示在窗體的標籤中的文本值。下面是我試過的代碼。任何人都可以幫助我嗎？

廣告順便說一句，你有很多的'這裏IDisposable'資源應該最好被包裹在'使用'陳述進行適當的確定性處理。 –

你能讓我知道更多回合嗎？ – user2605927

我會將它作爲答案發布。 –

當您在部門和指定讀取，存儲的ID的地方，就像在一個私人提起這個類的：

public partial class temporaryduty : System.Web.UI.Page 
{ 
    private int divisionId; 
    private int designationId;

...

if (objDs.Tables[0].Rows.Count > 0) 
{ 
    lbldiv.Text = objDs.Tables[0].Rows[0]["DIVISION"].ToString(); 
    lbldesig.Text = objDs.Tables[0].Rows[0]["Designation"].ToString(); 
    divisionId = objDs.Tables[0].Rows[0]["Expr1"]; 
    designationId = objDs.Tables[0].Rows[0]["Expr2"]; 
}

然後，您的按鈕點擊使用這些字段來插入ID：

cmd.Parameters.AddWithValue("@DIVID", divisionId); 
cmd.Parameters.AddWithValue("@DesigID", designationId);

哦好吧...我會試試這個喬希...並讓你知道:) – user2605927

聽起來不錯。如果它解決了您的問題，請隨時將其標記爲答案。 –

divisionId = objDs.Tables [0] .Rows [0] [「Expr1」];它給出了一個錯誤，說不能將對象轉換爲字符串... – user2605927

按照要求，這裏是爲IDisposable資源使用using的慣用方式。請注意，我已經做任何其他事情，代碼的邏輯但，因此要注意其他的答案:)
