vs2005 中ImageList中InvalidArgument=“1”的值对于“index”无效
private void Form1_Load(object sender, EventArgs e)
{
string path = Application.StartupPath.Substring(0,Application.StartupPath.Substring(0,Application.StartupPath.LastIndexOf("\\")).LastIndexOf("\\"));
path += @"\01.jpg";

Image ming2 = Image.FromFile(path2, true);
imageList1.Images.Add(ming2);
imageList1.ImageSize = new Size(200,165);
pictureBox1.Width = 200;
pictureBox1.Height = 165;

}

private void button1_Click(object sender, EventArgs e)
{
int a = 0;
if (a == (imageList1.Images.Count - 1))
{
a = 0;
}
else if(a<imageList1.Images.Count)
{
a = a + 1;
}

this.pictureBox1.Image=this.imageList1.Images[a];
}

private void button2_Click(object sender, EventArgs e)
{
pictureBox1.Image = imageList1.Images[1];
}
}

这是代码那里出错了啊，请大家帮忙

[解决办法]
ImageList没有2张图,所以不能用1,如果有1张图,用imageList1.Images[0];

[解决办法]

探讨
引用:
看这代码是看不出问题，你在 private void Form1_Load(object sender, EventArgs e) 的最后，private void button1_Click(object sender, EventArgs e) 最前，private void button2_Click(object sender, EventArgs e)
最前，……

[解决办法]

探讨
Application.StartupPath.Substring(0,Application.StartupPath.Substring(0,Application.StartupPath.LastIndexOf("\\")).LastIndexOf("\\"));
这句话是干嘛啊，好像是不是使用错误了

[解决办法]

C# code

我曾经也使用过ImageList，用下标取的时候，也是取不出来，也不知道什么原因;不过有解决办法：Image ming2 = Image.FromFile(path2, true);  imageList1.Images.Add(ming2);你添加的时候这样子添加： imageList1.Images.Add("ming2",ming2);给它添加一个key进去取的时候通过key来取例如imageList1["ming2"]这样子就可以取出来了。很奇怪，我怀疑是.net的bug
