任何人都知道在C#或任何.Net库中解析Lua数据结构的简单方法吗?这类似于JSON解码,除了Lua而不是javascript。
此时看起来我需要自己编写,但希望已经有了一些东西。

感谢你们两位,我使用LuaInterface
找到了我想要的东西这是Lua想要阅读的数据结构(“c:\ sample.lua”):
TestValues = {
NumbericOneMillionth = 1e-006,
NumbericOnehalf = 0.5,
NumbericOne = 1,
AString = "a string"
}
这是使用LuaInterface读取Lua数据结构的一些示例代码:
Lua lua = new Lua();
var result = lua.DoFile("C:\\sample.lua");
foreach (DictionaryEntry member in lua.GetTable("TestValues")) {
Console.WriteLine("({0}) {1} = {2}",
member.Value.GetType().ToString(),
member.Key,
member.Value);
}
以下是示例代码写入控制台的内容:
(System.String) AString = a string
(System.Double) NumbericOneMillionth = 1E-06
(System.Double) NumbericOnehalf = 0.5
(System.Double) NumbericOne = 1
要弄清楚如何使用库,我在Reflector中打开了LuaInterface.dll,并对成员函数进行了google。

亚历山大说的话。毕竟,实验室是Lua的故乡。
具体来说,LuaInterface可以允许Lua解释器嵌入到您的应用程序中,以便您可以使用Lua自己的解析器来读取数据。这类似于将Lua嵌入C / C ++应用程序中以用作配置/数据文件语言。 LuaCLR项目在某些方面也可能富有成效,但可能不会那么成熟。

LsonLib可以解析Lua数据结构,操纵它们并将结果序列化回Lua文本。完全披露:我是作者。它是纯C#并且没有依赖关系。
假设:
MY_VAR = { "Foo", ["Bar"] = "Baz" }
ANOTHER = { 235, nil }
基本用法:
var d = LsonVars.Parse(File.ReadAllText(somefile));
d["MY_VAR"][1].GetString() // returns "Foo"
d["MY_VAR"]["Bar"].GetString() // returns "Baz"
d["MY_VAR"][2] // throws
d["ANOTHER"][1].GetString() // throws because it's an int
d["ANOTHER"][1].GetInt() // returns 235
d["ANOTHER"][2] // returns null
d["ANOTHER"][1].GetStringLenient() // returns "235"
d["ANOTHER"][1] = "blah"; // now { "blah", nil }
d["ANOTHER"].Remove(2); // now { "blah" }
File.WriteAllText(somefile, LsonVars.ToString(d)); // save changes
(它实际上是我们在内部使用的JSON库的一个相当简单的端口,因此它具有相当多的功能并且可能留下一些JSON痕迹)

您可能(或可能不)在Lablua projects中找到所需内容。
无论如何,请不要犹豫,在Lua mailing list上提问。

我还没有看过这个,暂时保存一个链接: http://www.youpvp.com/blog/post/LuaParse-C-parser-for-World-of-Warcraft-saved-variable-files.aspx
不幸的是,LuaInterface只是打包在x86上运行,所以我在寻找替代方案。这是来源:/*
