範例

下列程式碼範例示範如何使用 OnAbortTransactionOnCommitTransaction 方法。The following code example demonstrates how to use the OnAbortTransaction and OnCommitTransaction methods. 由於 TemplateControl 是抽象類別,因此這個程式碼範例會使用衍生自 TemplateControl 類別的 Page 類別。Because TemplateControl is an abstract class, this code example uses the Page class, which is derived from the TemplateControl class. Account 是支援 Debit 作業的類別,此作業是交易式的,而且必須當做一個單位來執行。Account is a class that supports a Debit operation, which is transactional and must execute as a unit. 如果在此作業期間引發任何例外狀況,則會結束交易。If any exception is raised during this operation, the transaction is ended.


  private void Page_Load(object sender, System.EventArgs e)
  {
      AbortTransaction += new System.EventHandler(Sub_AbortTransaction);
   CommitTransaction += new System.EventHandler(Sub_CommitTransaction);
      try
   {
      Account myAccount = new Account();
      int someAmount = 500;
      myAccount.Debit(someAmount); 
      ContextUtil.SetComplete(); 
   }
   catch(Exception)
   {
      ContextUtil.SetAbort();
   }
  }

private void Sub_AbortTransaction(object sender,System.EventArgs e)
{
   // Code for RollBack activity goes here.
   Response.Write("Transaction Aborted");
}
private void Sub_CommitTransaction(object sender,System.EventArgs e)
{
   // Code for Commit Activity goes here.
   Response.Write("Transaction Commited");
}

   private Sub Page_Load(Sender As Object, e As EventArgs)

   AddHandler Me.myCommitTransaction,AddressOf Sub_CommitTransaction
   AddHandler Me.myAbortTransaction,AddressOf Sub_AbortTransaction

      try
   
      Dim myAccount As Account = New Account()
      Dim someAmount As Integer = 500
      myAccount.Debit(someAmount)
      ContextUtil.SetComplete()
   
   catch e1 As Exception
         ContextUtil.SetAbort()
   End Try
  End Sub

Public event myCommitTransaction As System.EventHandler 
 Public event myAbortTransaction As System.EventHandler
 
 protected overrides Sub  OnCommitTransaction(e As EventArgs )
  
       RaiseEvent myCommitTransaction(Me ,e)
       Response.Write("<br /><br />The 'OnCommitTransaction()' method is used to raise the 'CommitTransaction' event." )

End Sub
  
  protected  overrides Sub OnAbortTransaction(e As EventArgs)
       RaiseEvent myAbortTransaction(Me ,e)
       Response.Write("<br /><br />The 'OnAbortTransaction()' method is used to raise the 'AbortTransaction' event." )
  End Sub

private Sub Sub_AbortTransaction(Sender As Object, e As EventArgs)
  ' Code for RollBack activity goes here.
   Response.Write("Transaction Aborted")
End Sub

private Sub Sub_CommitTransaction(Sender As Object, e As EventArgs)
  ' Code for Commit Activity goes here.
   Response.Write("Transaction Commited")
End Sub

備註

您可以針對您的頁面或使用者控制項參與的任何交易處理邏輯使用 OnCommitTransaction 方法。You can use the OnCommitTransaction method for any transaction processing logic in which your page or user control participates.
