奇怪的private类型

更新时间：12/13/2004 9:08 PM

 

var log1 = new LoginClass("rerd");

trace(log1.getUserName());

//out.print:rerd

trace(log1.userName);

//out.print:rerd

userName1_txt.text = log1.userName;

//文字框显示rerd

//userName和getUserName()都是private，但仍然可以访问？？？

 

//

var log2:LoginClass = new LoginClass("rerd");

userName2_txt.text = log2.userName;

trace(log2.getUserName());

trace(log2.userName);

/**

产生如下编译错误,而且log1 相关的userName1_txt也无法显示值 log1.userName？？？

**Error** Scene=Scene 1, layer=Layer 1, frame=1:Line 39: The member is private and cannot be accessed.

     trace(log2.getUserName());

 

**Error** Scene=Scene 1, layer=Layer 1, frame=1:Line 40: The member is private and cannot be accessed.

     trace(log2.userName);

真的是很难理解啊！可能是因为严格数据类型指定时数据类型不匹配会触发编译器错误.在帮助中有这样一句话“还应注意成员访问控制是一个仅限于编译时的功能；在运行时，Flash Player 不区分私有或公共成员”这样就不难理解为什么会出现这种情况了
