Hey guys Need some help with this C# assignment:

创建一个名为LatestVisitedSites的项目，包含一个窗体，该窗体包含三个链接标签的列表，这些链接标签链接到任何三个网站 你选.当用户单击LinkLabel时，链接到该站点.当用户的鼠标悬停在LinkLabel上时，显示一条简短消息，说明站点的用途.用户单击链接后，将最近选择的链接移到列表顶部，然后 向下移动其他两个链接，并确保每个链接都保留正确的说明.

Create a project named RecentlyVisitedSites that contains a Form with a list of three LinkLabels that link to any three Web sites you choose. When a user clicks a LinkLabel, link to that site. When a user's mouse hovers over a LinkLabel, display a brief message that explains the site's purpose. After a user clicks a link, move the most recently selected link to the top of the list, and move the other two links down, making sure to retain the correct explanation with each link.

这是GUI表单的代码:

Here's the code of the GUI Form:

到目前为止，我已经完成了所有工作.但是当我单击它时，在将最近单击的链接移至顶部并将其他两个链接移至下方时，我需要帮助.最好是任何帮助.

So far I got everything done. But I need help in moving the recently clicked link up top and the other two down when I click on it. Any help would be best.

推荐答案

您可以将所有LinkLabel添加到FlowLayoutPanel并使用ControlCollection.SetChildIndex方法移动单击的链接.到顶部.从设计器中删除所有控件，然后尝试下面的完整示例代码，其中LinkLabels和FlowLayoutPanel 是通过程序创建的:

You could add all LinkLabel to a FlowLayoutPanel and use the ControlCollection.SetChildIndex method to move the clicked link to the top. Remove all controls from the designer and try the following complete sample code where the LinkLabels and the FlowLayoutPanel are created programmatically:

 public partial class Form1 : Form
    {
        LinkLabel googleLabel = new LinkLabel { Text = "Google" };
        LinkLabel facebookLabel = new LinkLabel { Text = "Facebook" };
        LinkLabel twitterLabel = new LinkLabel { Text = "Twitter" };

        FlowLayoutPanel panel = new FlowLayoutPanel();

        public Form1()
        {
            InitializeComponent();
            googleLabel.LinkClicked += googleLabel_LinkClicked;
            facebookLabel.LinkClicked += facebookLabel_LinkClicked;
            twitterLabel.LinkClicked += twitterLabel_LinkClicked;

            Controls.Add(panel);
            panel.Controls.Add(googleLabel);
            panel.Controls.Add(facebookLabel);
            panel.Controls.Add(twitterLabel);
        }

        private void googleLabel_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
        {
            System.Diagnostics.Process.Start("IExplore", "http://www.google.com");
            panel.Controls.SetChildIndex(googleLabel, 0);
        }

        private void facebookLabel_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
        {
            System.Diagnostics.Process.Start("IExplore", "http://www.facebook.com");
            panel.Controls.SetChildIndex(facebookLabel, 0);
        }

        private void twitterLabel_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
        {
            System.Diagnostics.Process.Start("IExplore", "http://www.twitter.com");
            panel.Controls.SetChildIndex(twitterLabel, 0);
        }
    }

希望有帮助.
