deployment - 如何从 .reg 文件生成 WiX XML？

Question

是否有工具可以在给定 .reg 文件的情况下生成 WiX XML？

<小时/>

在 2.0 中，您应该能够运行 Tallow 来生成注册表 XML:

tallow -r my.reg 

无论如何，我拥有的牛脂版本会生成空 XML。

在 3.0 中，牛脂已被热量取代，但我不知道如何让它从 .reg 文件生成输出。

在 3.0 中有办法做到这一点吗？

Answer 1

我找不到工具，所以我做了一个。

源代码可能不太优雅，但似乎可以工作:

using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using System.Xml;
using System.Text.RegularExpressions;

namespace Reg2Wix
{
    class Program
    {
        static void PrintUsage()
        {
            Console.WriteLine("reg2wix <input file> <output file>");
        }
