Asp.net if語句

我有一個IF語句的問題。Asp.net if語句

本聲明的目的是，所有3位經理必須先批准訂單，然後才能發行。

這是結：

Dim RstAllchk 
Dim RstAllchk_numRows 
Set RstAllchk = Server.CreateObject("ADODB.Recordset") 
RstAllchk.ActiveConnection = MM_DBConn_STRING 
RstAllchk.Source = "SELECT comitee.OrderNo, comitee.Bart, comitee.Carel, comitee.Charl    FROM comitee WHERE (((comitee.OrderNo)='" + Replace(RstAllData__varOrderNum, "'", "''") + "'));" 
RstAllchk.CursorType = 0 
RstAllchk.CursorLocation = 2 
RstAllchk.LockType = 1 
RstAllchk.Open() 
RstAllchk_numRows = 0 

    if (RstAllchk.Fields.Item("Bart").Value)= "Approved" then 
if (RstAllchk.Fields.Item("Carel").Value)= "Approved" then 
    if (RstAllchk.Fields.Item("Charl").Value)= "Approved" then 

set cdata1 = Server.CreateObject("ADODB.Command") 
cdata1.ActiveConnection = MM_DBConn_STRING 
cdata1.CommandText = " UPDATE TblOrderData SET Fldapproved = 'Approved' WHERE FldOrderID = '" & RstAllData__varOrderNum & "'" 
cdata1.CommandType = 1 
cdata1.CommandTimeout = 0 
cdata1.Prepared = true 
cdata1.Execute() 
cdata1.ActiveConnection.Close 

set cdata2 = Server.CreateObject("ADODB.Command") 
cdata2.ActiveConnection = MM_DBConn_STRING 
cdata2.CommandText = " UPDATE TblOrderDetail SET FldMainapproved = 'Approved' WHERE FldOrderNum = '" & RstAllData__varOrderNum & "'" 
cdata2.CommandType = 1 
cdata2.CommandTimeout = 0 
cdata2.Prepared = true 
cdata2.Execute() 
cdata2.ActiveConnection.Close

有時候如果只有一個經理確認訂單，訂單仍在批准。我一直在爲此掙扎好幾天。希望你們中的任何人都能給我一些建議。

花花公子硬編碼值？並且你的SQL語句應該被參數化。那裏有一些很好的SQL注入風險。 – Eonasdan

假設VB.NET：

IF (RstAllchk.Fields.Item("Bart").Value = "Approved" AND _ 
    RstAllchk.Fields.Item("Carel").Value = "Approved" AND _ 
    RstAllchk.Fields.Item("Charl").Value = "Approved") THEN

在C＃：

if (RstAllchk.Fields.Item("Bart").Value == "Approved" && 
    RstAllchk.Fields.Item("Carel").Value == "Approved" && 
    RstAllchk.Fields.Item("Charl").Value == "Approved")

你的c＃需要'=='而不是'=' – Scott

@Scott - 你可以自己編輯它......如果你看到一個明顯的錯誤 - 糾正它。這是堆棧溢出的方式。 – Oded

用C＃（& &是並且，==等於）

if (RstAllchk.Fields.Item("Bart").Value == "Approved" 

&& RstAllchk.Fields.Item("Carel").Value == "Approved" 

&& RstAllchk.Fields.Item("Charl").Value == "Approved" 
) 

{ 

    //treatment 

}

你可以合併所有像

(if var1 == x && var2 == y && var3 == z) { 
    //Do what you want 
}
