}

}

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;
