C#控件的触发函数怎么带自定参数？

比如 this.comboBox.SelectedIndexChanged += new System.EventHandler(comboBox_SelectedIndexChanged); private void comboBox_SelectedIndexChanged(object sender, EventArgs e){}我想在触发执行comboBox_SelectedIndexChanged（）时加一个我自定义的参数，用于区分我触发这件事的时间不同(或其它)，要怎么弄呢类似comboBox_SelectedIndexChanged（s, e , time）;

这个。。。加不了。你这样写看符合你要求不：private void comboBox_SelectedIndexChanged(object sender, EventArgs e){
DateTime time = DateTime.Now;
myboxChange(sender,e,time);}void myboxChange(object sender, EventArgs e,DateTime time){ //修改这里面的就可以了}...

用委托吧this.comboBox.SelectedIndexChanged+=delegate(n,m){comboBox-SelectedIndexChanged(n,e,time);}...
