可访问性低？？？那位高手解决一下啊

那位高手指教一下
--------------------编程问答-------------------- 很明显嘛，将冲突的两个方法的访问修饰符改成一致就行了 --------------------编程问答-------------------- namespace _3sdnMap1
{
public class ControlsSynchronizer
{
... --------------------编程问答-------------------- class ControlsSynchronizer 这个没有加public
msdn：
如果在类的内部声明的类型没有访问修饰符，则该类型默认为 private。
补充：.NET技术 , C#
