怎么会报错显示不存在read2write方法
protected void Button1_Click(object sender, EventArgs e)
{
if (RadioButtonList1.SelectedValue != "")
{
int selectvalue = Convert.ToInt32(RadioButtonList1.SelectedValue);
switch(selectvalue)
{
case 1:
read2write(1);
break;
case 2:
read2write(2);
break;
case 3:
read2write(3);
break;
case 4:
read2write(4);
break;
}
button
------解决方案--------------------如果你只想编译通过,最简单的就是定义一个(当然啥也没有做)
void read2write(int n) { }
写在窗体类定义的空白处,不要写在函数里面哦。
