Wix：无法通过自定义操作设置属性

Question

我的安装程序中有一个对话框，用于输入激活密钥。 我可以通过此控件传递值，

         <Control Id="KEY1" Type="Edit" Property="KEY1" Height="17" Width="45" X="50" Y="150" Text="{5}" Indirect="no"/>

按照我的习惯行动

 session["KEY1"]

但是我似乎无法弄清楚为什么我不能设置session [“ KEY1”] =“ test”并看到控件中的值...我尝试了一切，但无济于事。 这是我当前的代码，

C＃（自定义操作）

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.Deployment.WindowsInstaller;

namespace Test.CustomActions
{
    public class CustomActions
    {
        [CustomAction]
        public static ActionResult TestAction(Session session)
        {
            session.Log("Begin CustomAction1");

            session["KEY1"] = "lol";
            string[] lines = { session["KEY1"], "Second line", "Third line" };
            System.IO.File.WriteAllLines(@"C:\CustomAction.txt", lines);

            return ActionResult.Success;
        }
    }
}

Answer 1

您的InstallExecuteSequence / InstallUISequence代码在哪里？

<InstallUISequence>
    <Custom Action="Testing" Sequence="1" />
</InstallUISequence>

也许添加它会使此自定义操作在调用UI对话框之前发生。

编辑：另外，您是否已完成安装程序的任何详细调试（详细日志记录），以检查正在发生的事情以及何时运行？ 输出.MSI后，打开命令提示符并执行以下操作：

    msiexec.exe /i <yourmsi> /l*vx Output.txt

这将为您提供详细的信息输出！
