在 CustomAction 期间从 WiX 检索变量

Question

我正在尝试在安装过程中从 WiX 检索变量。这是我尝试过的测试：

try
{
    string reqid = session["REQUESTID"];
    TraceLog.LogMessage("CustomAction => ReportUpgradeStatus: Straight Session is valid");
}
catch
{
    TraceLog.LogMessage("CustomAction => ReportUpgradeStatus: Straight Session is invalid");
}
try
{
    string reqid = session.CustomActionData["REQUESTID"];
    TraceLog.LogMessage("CustomAction => ReportUpgradeStatus: CustomActionData is valid");
}
catch
{
    TraceLog.LogMessage("CustomAction => ReportUpgradeStatus: CustomActionData is invalid");
}
try
{
    string reqid = session.GetProductProperty("REQUESTID");
    TraceLog.LogMessage("CustomAction => ReportUpgradeStatus: GetProductProperty is valid");
}
catch
{
    TraceLog.LogMessage("CustomAction => ReportUpgradeStatus: GetProductProperty is invalid");
}

我在 Product.wxs 中有一些 xml 是这样的：

<InstallExecuteSequence>
  <Custom Action="SetRequestIdProp" Before="InstallFiles" />  
  <Custom Action="ReportUpgradeStatusMVACA" After="SetRequestIdProp" />    
  <ScheduleReboot After="InstallFinalize"/>
</InstallExecuteSequence>

<Fragment>
  <Binary Id="CustomActionBinary" SourceFile="..\..\..\Bin$(var.Configuration)\InstallationCA.CA.dll"/>    
  <Property Id="REQUESTID" Value="[REQUESTID]" />   
  <CustomAction Id="SetRequestIdProp" Property="REQUESTID" Value="[REQUESTID]" />    
  <CustomAction Id="ReportUpgradeStatusMVACA" 
              BinaryKey="CustomActionBinary" 
              DllEntry="ReportUpgradeStatusMVA" 
              Execute="commit" 
              Return="check" />
</Fragment>

如何访问 RequestID 属性？我在这里真的不知所措，因为我试图使该值出现的一切都没有任何作用。

欢迎任何建议。

编辑：问题已解决。这是我需要做的：

我将 CustomAction 更改为：

<CustomAction Id="SetRequestIdProp" 
              Property="ReportUpgradeStatusMVACA" 
              Value="REQUESTID=[REQUESTID];APPLIANCEID=[APPLIANCEID];SERVICEURL=[SERVICEURL];STATUSDIR=[STATUSDIR];AUTOUPDATE=[AUTOUPDATE]" />
<CustomAction Id="ReportUpgradeStatusMVACA" 
              BinaryKey="CustomActionBinary" 
              DllEntry="ReportUpgradeStatusMVA" 
              Execute="deferred" 
              Return="check"
              HideTarget="no" />

我的 InstallExecuteSequence 为：

<Custom Action="SetRequestIdProp" Before="ReportUpgradeStatusMVACA" />
<Custom Action="ReportUpgradeStatusMVACA" Before="InstallFinalize" />

我使用以下方法获取信息：

RequestId = Int32.Parse(session.CustomActionData["REQUESTID"]),
ApplianceId = Int32.Parse(session.CustomActionData["APPLIANCEID"]),
ServiceUrl = session.CustomActionData["SERVICEURL"],

感谢您的帮助。

您的自定义操作是提交自定义操作（我想知道为什么 - 这很不寻常）。这意味着它也是延迟的，所以你需要通过 CustomActionData 传递数据，这似乎是一个很好的解释：
