如何知道在asp.net中点击了哪张随机图片

<asp:Image ID="Image1" runat="server" ImageUrl="image1.jpg" OnClick="Image_Click" />
<asp:Image ID="Image2" runat="server" ImageUrl="image2.jpg" OnClick="Image_Click" />
<asp:Image ID="Image3" runat="server" ImageUrl="image3.jpg" OnClick="Image_Click" />

protected void Image_Click(object sender, EventArgs e)
{
    Image clickedImage = (Image)sender;
    string clickedImageID = clickedImage.ID;

    // 根据点击的图片ID执行相应的操作
    if (clickedImageID == "Image1")
    {
        // 点击了图片1的处理逻辑
    }
    else if (clickedImageID == "Image2")
    {
        // 点击了图片2的处理逻辑
    }
    else if (clickedImageID == "Image3")
    {
        // 点击了图片3的处理逻辑
    }
}
