急急急！！！如何把字符串赋予为控件的ID值
在aspx页面上，
for(int i=1;i<6;i++)
{
string m="btn"+i;
}
现在m的值为btn1,btn2,btn3,btn4,btn5我想把一个button控件的id值也为btn1,...btn5.如何关联呢？
我用(button)this.controls.Find(m,true)[0] 系统提示有错，错误信息为system.web.controlcollection不包含Find的定义。

没太明白你的意思。上面是要给button赋值，下面怎么又是通过id名来find控件？是还没赋ID给他想动态指定ID给控件还是？？？？？
