lua string include zero bytes cannot pass to function receive byte[] parameter

[xophiix]

in C#

void foo(byte[]) {
}

// binding code is
MyType self=(MyType)checkSelf(l);
System.Byte[] a1;
checkType(l,2,out a1);
self.foo(a1);

it doesn't work because no string to byte[] conversion allowed directly.

so I have to write my own MonoPInvoke function like:

[MonoPInvokeCallbackAttribute(typeof(LuaCSFunction))]
static public int foo(IntPtr l) {
    MyType self=(MyType)LuaObject.checkSelf(l);
    int bytesLen;
    IntPtr ptr = LuaDLL.lua_tolstring(l, 2, out bytesLen);
    byte[] bytes = new byte[bytesLen];
    for (int i = 0; i < bytesLen; ++i) {
        bytes[i] = (byte)Marshal.ReadByte(ptr, i);
    }
    self.foo(bytes);
}

If the engine can include this kind of conversion code, it will be better.

I think maybe I should fork slua and send some pull request :)

I've written function that convert byte[] to lua string, but some user prefer keeping as ud. So i don't make a decision how to pass byte[] , you can do it yourself.

I think keeping as ud , and supply a function that convert ud to str is better.
