LuaInterface:访问对象属性
问题描述:
我使用LuaInterface为我想在Lua中提供的某些对象注册getter。 E.G:LuaInterface:访问对象属性
public MyObject getObjAt(int index)
{
return _myObjects[index];
}
我的Lua文件:
obj = getObjAt(3)
print(obj.someProperty) // Prints "someProperty"
print(obj.moooo) // Prints "moooo"
print(obj:someMethod()) // Works fine, method is being executed
究竟如何,我可以在Lua回国后,他们访问公共对象属性?这甚至可能或者我必须为每个对象属性编写getter?
答
您可能会发现这个代码在了解了如何访问属性的有用:
class Lister
{
public string ListObjectMembers(Object o)
{
var result = new StringBuilder();
ProxyType proxy = o as ProxyType;
Type type = proxy != null ? proxy.UnderlyingSystemType : o.GetType();
result.AppendLine("Type: " + type);
result.AppendLine("Properties:");
foreach (PropertyInfo propertyInfo in type.GetProperties())
result.AppendLine(" " + propertyInfo.Name);
result.AppendLine("Methods:");
foreach (MethodInfo methodInfo in type.GetMethods())
result.AppendLine(" " + methodInfo.Name);
return result.ToString();
}
}
和注册功能:
static Lister _lister = new Lister();
private static void Main() {
Interpreter = new Lua();
Interpreter.RegisterFunction("dump", _lister,
_lister.GetType().GetMethod("ListObjectMembers"));
}
然后在Lua:
print(dump(getObjAt(3)))
