RadioButtonList绑定图片

本博文是让你学会读取站点某一目录的图片,掌握LINQ与泛型Dictionary<TKey,TValue>的使用。

首先准备好几张图片存在站点某一目录之下,本例中的存储图片的目录名为MsSiteImages,图片你可以从微软网站下载http://windows.microsoft.com/en-US/windows/home

我们写一个泛型数据集,将存储目录的图片信息:

View Code
 private Dictionary<int, string> GetData()
    {
        Dictionary<int, string> dic = new Dictionary<int, string>();
        int i = 0;
        System.IO.FileInfo fi;

        var Images =
            from f in System.IO.Directory.GetFiles(Server.MapPath("MsSiteImages"))
            orderby f descending
            select f;

        foreach (var filename in Images)
        {
            fi = new System.IO.FileInfo(filename);

            dic.Add(i, "<img src='" + "MsSiteImages/" + fi.Name + "' alt='" + fi.Name +
                "' title='" + fi.Name + "'/>");
            i++;
        }

        return dic;
    }


创建一个网页,并拉RadioButtonList控件进入网页:

View Code
<asp:RadioButtonList ID="RadioButtonList1" runat="server"></asp:RadioButtonList>


写一个方法,用来绑定数据给RadioButtonList控件,其中一个绑定类别,你可以从下面地址下载:http://www.cnblogs.com/insus/archive/2013/01/28/2880618.html ,解压之后,把InsusListControlUtility.dll放入站点的BIN目录中。

View Code
 private void Data_Binding()
    {
        Insus.NET.InsusListControlUtility objList = new Insus.NET.InsusListControlUtility();
        objList.RadioButtonListParse(this.RadioButtonList1, GetData(), "value", "key");
    }


在网页的Page_Load中,引用上面的Data_Binding()方法:

View Code
 protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
            Data_Binding();
    }


运行网页的效果:
