lua 语法

三元表达式：

    lua :
    a = 1
    b = (a == 1) and "one" or "not one"

    c# :
     bool a = 1;
     string b = a == 1 ? "one" : "not one";

while循环

    lua :
    a = 1
    while a~= 5 do  -- Lua uses ~= to mean not equal
    a = a + 1
    print("a  : ", a)

doWhile循环

    lua :
    a = 0;
    repeat
        a = a + 1
        print(a)
    until a == 5

    c# :
    int a = 0;
    do{
        a = a + 1;
        print(a);
    } while(a == 5)

break中断循环

    lua :
    a = 0
    while true do
    a = a + 1
        if a == 10 then
            break;
        end
    end

    c# :
    int a = 0;
    while(true){
        a += 1;
        if(a == 10)
        break;  
    }

无参数无返回值的函数

    lua :
    function MyFirstLuaFunction()
        print("first")
    end

    c# :
    void MyFirstLuaFunction(){
        print("first");
    }

多个参数多个返回值的函

    lua :
    function LuaFunction(a, b, c)
        return a, b, c, true
    end

    { 使用
        a, b, c, d = LuaFunction("aa", 1, .3)   
        print(a, b, c, d)

        ---- outPut ----
        aa  1   0.3   true

    }

    c# : // c#返回不了多个值，可以有多参数
