把上面的语句改成delphi,错误在什么地方?
button1.click:=System.EventHandler.Create(Button1_click);
编译时提示没有完整的参数!

首先，Delphi里面就没有System.EventHandler这个东西，Delphi的事件都是在消息里面
赋值的变量。
C＃里面引入的事件和Java几乎一样，Java里面这样写：
Button1.addMouseListener(new java.awt.event.MouseAdapter()
{
public void mouseClicked(MouseEvent e)
{
Button1_mouseClicked(e);
}
});
void Button1_mouseClicked(MouseEvent e)
{
//这里写你想处理的事情
}

Delphi里面没有EventHandler
改Delphi应该是Button1.OnClick := Button1_Click;

不应该说delphi里没有,是vcl中没有,我用的是delphi for .net preview带的编译器,和.net freamwork类库,
没有使用vcl,eventhandler是system类中的事件托管,我想了解的是eventhandler在delphi中的
用法.并不是什么硬套.

另外,Button1.OnClick := Button1_Click;根本就不能编译,因为
button1是system.web.ui.webcontrol中的控件,onclick不是事件而是方法用来
引发click事件,和VCL中BUTTON完全不同!
