範例

下列程式碼範例示範如何註冊事件的自訂事件處理常式 CommitTransactionThe following code example demonstrates how to register a custom event handler for the CommitTransaction event. 由於 TemplateControl 是抽象類別,因此這個程式碼範例 Page 會使用衍生自類別的類別 TemplateControlBecause TemplateControl is an abstract class, this code example uses the Page class, which is derived from the TemplateControl class. Account 是支援作業的類別, Debit 它是交易式,而且必須以單位的形式執行。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,就會結束交易。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

  ' Code for RollBack activity goes here.
