Question

C#“button7_Click”的重载均与委托“System.EventHandler”不匹配

private void button7_Click(object sender, PrintPageEventArgs e)
{}
this.button7.Click += new System.EventHandler(this.button7_Click);

错误提示： “button7_Click”的重载均与委托“System.EventHandler”不匹配

Answer 1

private void button7_Click(object sender, EventArgs e)
{}

根据上方内容修改.即可.

PrintPageEventArgs这个参数是打印参数

您的应该写成默认参数.

所以报错了

Answer 2

private void button7_Click(object sender, PrintPageEventArgs e)

PrintPageEventArgs e 这个事件写错了，看看它自动生成的吧。。应该就是

button1_Click(object sender, EventArgs e)
