lua字符串转bytes 与c#数据交换

str = 'abc你好'
res = ""
for i=1, string.len(str) do
    local b = string.byte(string.sub(str,i,i))
    res = res .. b .. ","
end

print(res)

var bytes = new byte[] { 97, 98, 99, 228, 189, 160, 229, 165, 189, };
var reult = Encoding.UTF8.GetString(bytes);
Console.WriteLine(reult);
