Question

我正在使用Wix版本3.9R2

我按照建议here在我的产品的安装/修复/卸载中创建了可持久的属性。

安装时，从命令行设置的属性会正确发送到我的自定义操作方法。当我重新安装产品时，他们没有，尽管日志显示属性填充了正确的值。这是我的install logs（安装和修复）。

另外，这是我的wxs文件。我省略了一些我认为不相关的部分。

这是我的C＃动作方法。

[CustomAction]
public static ActionResult DeployDatabase(Session session)
{
    try
    {
        session.Log("Begin DeployDatabase");

        var connectionString = session["DATABASECONNECTIONSTRING"];
        var databaseName = session["DATABASENAME"];
        var dacpacLocation = session["DATABASEDACPACLOCATION"];

        session.Log("Starting database deploy with...");
        session.Log("   ConnectionString=" + connectionString);
        session.Log("   DatabaseName=" + databaseName);
        session.Log("   DacpacLocation=" + dacpacLocation);

        if (string.IsNullOrEmpty(connectionString))
        {
            session.Log("Connection string must be provided.");
            return ActionResult.Failure;
        }

        if (string.IsNullOrEmpty(connectionString))
        {
            session.Log("Database name must be provided.");
            return ActionResult.Failure;
        }

        if (string.IsNullOrEmpty(dacpacLocation))
        {
            session.Log("Dacpac must be provided.");
            return ActionResult.Failure;
        }

        if (!File.Exists(dacpacLocation))
        {
            session.Log("The dacpac doesn't exist at " + dacpacLocation + ".");
            return ActionResult.Failure;
        }

        SqlPackage.Deploy(dacpacLocation, connectionString, databaseName, (messageType, message) => session.Log("Sql deploy message: " + messageType + ": " + message));

        return ActionResult.Success;
    }
    catch (Exception ex)
    {
        session.Log("Error deploying database.");
        var exception = ex;
        while (exception != null)
        {
            session.Log("---");
            session.Log("Message:" + exception.Message);
            session.Log("Stacktrace:" + exception.StackTrace);
            session.Log("---");
            exception = exception.InnerException;
        }
        return ActionResult.Failure;
    }
}

在修复日志中，您可以看到它正确设置属性。

Property(C): DATABASECONNECTIONSTRING = Data Source=(localdb)\ProjectsV12;Integrated Security=True;Connect Timeout=30;Encrypt=False;TrustServerCertificate=False

但是，在我的自定义操作中，我无法检索此属性。

Starting database deploy with...
   ConnectionString=
   DatabaseName=
   DacpacLocation=C:\Users\Paul\AppData\Local\Temp\tmpA791.tmp

为什么这个相同的msi在安装过程中给我正确的属性值，但没有修复？

Answer 1

WiX使用Property元素上的Secure属性来构建SecureCustomProperties property。

SecureCustomProperties是由以下分隔的公共属性列表分号。这些属性包含在默认列表中安装程序可以传递给服务器的受限公共属性使用提升的权限进行托管安装时的一面。

FWIW，在我看来，记住我的财产模式是不完整的。我通常也会更进一步地实现属性源优先级模式。我们的想法是，在命令行传递或在UI中选择的值应覆盖记忆值，该值应覆盖默认值。

Answer 2

属性应标记为Secure =：yes“如果它们要从UI序列转移到服务器的执行顺序中 - 这可能是问题。

WIx＆＃34;记住财产模式＆＃34;不允许在自定义操作中使用属性
