throw new NotImplementedException()是什么意思呢
Form f1 = new Form();
f1.FormClosing += new FormClosingEventHandler(f1_FormClosing);
f1.Show();
void f1_FormClosing(object sender, FormClosingEventArgs e)
{
throw new NotImplementedException();
}
程序自动添加的throw new NotImplementedException();
是什么意思呢?当我关闭f1的时候会有个错误,但注释之后又没错误
求指点一二
