例外処理、ロギングの管理にEnterpriseライブラリ5を使用しています。例外処理設定のデフォルトポリシーですべての例外に2つのハンドラーを設定し、最初にDBで例外をログに記録し、2番目のラップハンドラーで新しい例外をスローします。そして私は例外をログに記録するためにこのコードを書きました：
public void Save(OrderHeader orderHeader)
{
....
try
{
throw new Exception("Test");
}
catch (Exception e)
{
Dictionary<object, object> parameters = new Dictionary<object, object>();
//e.Data["Order"] = orderHeader.OrderId;
//e.Data["Customer"] = orderHeader.Customer;
ExceptionManager exManager = EnterpriseLibraryContainer.Current.GetInstance<ExceptionManager>();
if (exManager.HandleException(e, "Policy"))
{
throw;
}
}
}
ログに記録されたデータ（orderHeader.OrderId、orderHeader.Customerなど）に追加情報を保存したい。だから私は私のテキストフォーマッターテンプレートを（拡張プロパティを追加する）に変更します：
Message: {message}{newline}
Category: {category}{newline}
Priority: {priority}{newline}
EventId: {eventid}{newline}
Severity: {severity}{newline}
Title:{title}{newline}
Machine: {localMachine}{newline}
App Domain: {localAppDomain}{newline}
ProcessId: {localProcessId}{newline}
Process Name: {localProcessName}{newline}
Thread Name: {threadName}{newline}
Win32 ThreadId:{win32ThreadId}{newline}
Extended Properties: {dictionary({key} - {value}{newline})}
これらのコードとテンプレートを使用すると、すべてがOKで、例外がデータベースにログインします（追加のデータを書き込むためのコードはまだ記述していません）が、コードのコメント付きの2行のコメントを外すと、DBに何も保存されません。動作しないコードは次のとおりです。
public void Save(OrderHeader orderHeader)
{
....
try
{
throw new Exception("Test");
}
catch (Exception e)
{
Dictionary<object, object> parameters = new Dictionary<object, object>();
e.Data["Order"] = orderHeader.OrderId;
e.Data["Customer"] = orderHeader.Customer;
ExceptionManager exManager = EnterpriseLibraryContainer.Current.GetInstance<ExceptionManager>();
if (exManager.HandleException(e, "Policy"))
{
throw;
}
}
}
これも私のapp.configです：
