C# 利用正则表达式获取富文本框中所有Img Src路径

废话不多说，直接上代码：

Main程序

            string content = "<p><img src="/Uploads/Images/UEditor/2020052417350496181.jpg" title="pic.jpg" alt="pic.jpg"/></p><p><br/></p><p><img src="/Uploads/Images/UEditor/2020052417361071834.jpg" title="pic2.jpg" alt="pic2.jpg"/></p><p><br/></p>";
            string[] aa = GetHtmlImageUrlList(content);
            foreach (var item in aa)
            {
                Console.WriteLine(item);
            }
            Console.ReadKey();

获取Img的路径方法

   /// <summary>
        /// 获取Img的路径
        /// </summary>
        /// <param name="htmlText">Html字符串文本</param>
        /// <returns>以数组形式返回图片路径</returns>
        public static string[] GetHtmlImageUrlList(string htmlText)
        {
            Regex regImg = new Regex(@"<img[^<>]*?src[s	
]*=[s	
]*[""']?[s	
]*(?<imgUrl>[^s	
""'<>]*)[^<>]*?/?[s	
]*>", RegexOptions.IgnoreCase);
            //新建一个matches的MatchCollection对象 保存 匹配对象个数(img标签)
            MatchCollection matches = regImg.Matches(htmlText);
            int i = 0;
            string[] sUrlList = new string[matches.Count];
            //遍历所有的img标签对象
            foreach (Match match in matches)
            {
                //获取所有Img的路径src,并保存到数组中
                sUrlList[i++] = match.Groups["imgUrl"].Value;
            }
            return sUrlList;
        }
