我使用LuaInterface库在.net中运行lua,效果很好。我可以通过lua访问CLR。但是如何从C#调用Lua函数呢?

你需要找一个 LuaFunction ,从中可以使用Call()函数。

无论如何, here's a newer link to a Channel 9 blog post that has some sample code .

Test.lua文件将包含:

-- Function sums up two variables
function SumUp(a, b)
    return a + b;
end

function GetTable()
    local table =
    {
        FirstName = "Howard",
        LastName = "Wolowitz",
        Degree = "just an Engineer :)",
        Age = 28
    };

    return table;
end;

您的C代码如下所示:

static void Main(string[] args)
    {
        try
        {
            Lua lua = new Lua();
            lua.DoFile(@"D:\Samples\Test.lua");

            // SumUp(a, b)
            var result = lua.DoString("return SumUp(1, 2)");
            Console.WriteLine("1 + 2 = " + result.First().ToString());

            // GetTable()           
            var objects = lua.DoString("return GetTable()"); // Array of objects
            foreach (LuaTable table in objects)
                foreach (KeyValuePair<object, object> i in table)
                    Console.WriteLine($"{i.Key.ToString()}: {i.Value.ToString()}");
        }
        catch (Exception ex)
        {
            Console.WriteLine("Exception: " + ex.ToString());
        }
        Console.WriteLine("Press any key...");
        Console.ReadKey();
    }
