timer1.Enabled != timer1.Enabled;
if (timer1.Enabled==true)
{
timer1.Start();
}
else
{
timer1.Stop();
}
}
private void timer1_Tick(object sender, EventArgs e)
{
//if (count < ilImgList.Images.Count - 1)
//{
// count++;
//}
//else
//{
// count = 0;
//}
//picPicture.Image = ilImgList.Images[count];
i++;
if (i < 9)
{
picPicture.Image = ilImgList.Images[i];
}
else
{
MessageBox.Show("已经是最后一张了", "提示", MessageBoxButtons.OK, MessageBoxIc on.Exclamation);
}
}
}
}
显示：“timer1.Enabled != timer1.Enabled;”只有assignmeng、calldecrement和new对象表达式可用作语句还有我里面一部分是注释的，问为什么那边不能用那种形式写？

检举
timer1.Enabled != timer1.Enabled;
if (timer1.Enabled==true)
{
timer1.Start();
}
else
{
timer1.Stop();
}
改成timer1.Enabled = !timer1.Enabled;。
