Question

安装程序事务和ExternalUI的奇怪行为会破坏我的日志文件。

我在此交易中链接了三个MSI。我为每个安装程序创建了一个详细的日志文件。最后，我的“最后”详细日志将被删除。它始终是“最后一个”。

我做错了什么？如何避免这种行为？

在我提交交易

之后会发生这种情况

transaction.Commit();

正好在这里：

 private void End(bool commit)
 {
     uint ret = NativeMethods.MsiEndTransaction(commit ? 1 : 0);
 }

我的上一个日志文件将被删除并替换为这个镜头：

来自我的班级：

using (Transaction transaction = new Transaction("Install", TransactionAttributes.None))

foreach (MsiPackage package in _availableMsiPackages.Values){

  Installer.EnableLog(InstallLogModes.Verbose, LogPath);
  Installer.SetInternalUI(InstallUIOptions.Silent);
  ExternalUIRecordHandler _processMessageHandler = new ExternalUIRecordHandler ProcessMessage);
  ExternalUIRecordHandler result = Installer.SetExternalUI(_processMessageHandler, InstallLogModes.Verbose);

  Installer.InstallProduct(fi.FullName, _commandLine);
}

transaction.Commit();

您是否尝试过调用EnableLog（）的四参数版本？在该版本中，第三个参数允许您将其置于追加模式，第四个参数启用刷新。我猜测不附加模式适用于在Commit（）期间重新打开日志文件。如果您仍想在开头截断，可以在开始安装之前删除任何现有文件。

Installer.EnableLog(InstallLogModes.Verbose, LogPath, true, true);

使用ExternalUI的安装程序事务会破坏我的日志文件
