委托方法应在一定条件下自动调用 [英] Delegate method should be invoke automatically by some condition
本文介绍了委托方法应在一定条件下自动调用的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
public delegate void TimeDurationPopup();
public static int i = 0;
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
TimeDurationPopup f = new TimeDurationPopup(Check);
f();
}
}
protected void btn_Click(object sender, EventArgs e)
{
i += 1;
}
private void Chec()
{
if(i==5)
{
//TODO my logic
}
}
在这里,当我单击按钮时,我将增加I值.
如果我重视得到5,我想做一些逻辑.但是我不想像方法那样调用.
我值5时应自动调用该方法.希望我可以通过使用委托来解决此问题.
所以请给我一些想法.
谢谢.
Here when I am clicking the button I am increment the I value.
If I value getting 5 I want to do some logic. But I don''t want call like a method.
That method should be invoke automatically when I value getting 5. I hope I can do this problem by using delegates.
So please give me some idea.
Thanks.
推荐答案
我认为我们不能为整数等数据类型提供委托或事件处理程序.相反,您可以具有这样的功能.
I think we cannot have a delegate or event handler for datatypes like integer. instead you can have a function like this..
Private int i = 0;
Public int SetGetValue
{
get
{
return i;
}
set
{
if (value == 5)
{
// do your logic
}
else
{
this.i=value;
}
}
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
}
}
protected void btn_Click(object sender, EventArgs e)
{
this.SetGetValue=(this.SetGetValue)+1;
}
希望对您有帮助....
