<pre id=\"best-answer-content\" class=\"reply-text mb10\">this.timer1.Enabled = false;

this.timer2.Enabled = true;

this.Opacity = 0;//这一句表示将窗体透明度初始化为0;如果不加这一句，则为默认,默认为1;

<pre class=\"replyask-text\" id=\"content-5044651\">this.Opacity = 1;
那this.Opacity = 11;呢？我试过效果也差不多是透明度为11%

为何要这样输入？timer2透明度不是已经可以一直增加了吗？为何删去this.Opacity = 0;就没那个效果了

{

this.timer1.Enabled = false;

this.timer2.Enabled = true;

this.Opacity = 0;

}

this.Opacity = 0; this.Opacity = 1; 为何效果不同 什么意思？求详解
