Wix CustomAction [C＃] session.Message在安装期间未显示

Question

这是WIX脚本片段

<InstallExecuteSequence>
    <Custom Action="Warning" After="InstallFinalize">NOT INSTALLED</Custom>
</InstallExecuteSequence>
<CustomAction Id="Warning" BinaryKey="ExtendedActions" DllEntry="WarningAboutUpgrade" Execute="immediate" Return="check"/>
<Binary Id="ExtendedActions" SourceFile="$(var.ExtendedActions.TargetDir)$(var.ExtendedActions.TargetName).CA.dll" />

这是c＃自定义操作代码

using Microsoft.Deployment.WindowsInstaller;

namespace ExtendedActions
{
    public class CustomActions
    {
        [CustomAction]
        public static ActionResult WarningAboutUpgrade(Session session)
        {
            session.Log($"Begin CustomAction WarningAboutUpgrade");
            session.Message(InstallMessage.Info, new Record { FormatString = "Product updated. To upgrade Project execute initHeating.ps1 }" });
            return ActionResult.Success;
        }
    }
}

在安装过程中消息未显示;

Answer 1

这是因为您使用参数 InstallMessage.Info 调用 session.Message 。这导致文本不会显示给用户。可以在日志文件中找到该消息。这种行为是设计使然。

要归档您的目标，请将第一个参数更改为 InstallMessage.Warning 或 InstallMessage.Error

session.Message(InstallMessage.Warning, new Record 
{ 
  FormatString = "Product updated. To upgrade Project execute initHeating.ps1" 
});
