c# DataTable之增、删、查、改

添加：

//构建表
        DataTable dt = new DataTable("TempTable");
        
        //构建列
        DataColumn dc1 = new DataColumn("ThumbnailURL", Type.GetType("System.String")); //缩略图路径
        DataColumn dc2 = new DataColumn("ThumbAlternateText", Type.GetType("System.String"));   //替换文字
        DataColumn dc3 = new DataColumn("PictureShowURL", Type.GetType("System.String"));   //图片路径
        DataColumn dc4 = new DataColumn("PicAlternateText", Type.GetType("System.String")); //替换文字
        DataColumn dc5 = new DataColumn("Title", Type.GetType("System.String"));    //标题
        DataColumn dc6 = new DataColumn("Description", Type.GetType("System.String"));  //图片描述
        DataColumn dc7 = new DataColumn("LinkURL", Type.GetType("System.String"));  //链接
        dt.Columns.Add(dc1);
        dt.Columns.Add(dc2);
        dt.Columns.Add(dc3);
        dt.Columns.Add(dc4);
        dt.Columns.Add(dc5);
        dt.Columns.Add(dc6);
        dt.Columns.Add(dc7);

        //构建行
        for (int i = 0; i < 4; i++)
        {
            DataRow dr = dt.NewRow();
            dr["ThumbnailURL"] = "UserControl/ImgToggle/163Switcher/images/s" + i + ".jpg";
            dr["ThumbAlternateText"] = null;
