提取CuteEditor编辑器中的图片地址,并将远程图片保存到本地

using System.Net;

Regex re = new Regex(@"src\s*=\s*(?:([""'])(?<src>[^""']+)\1|(?<src>[^\s>]+))", RegexOptions.IgnoreCase | RegexOptions.Singleline);

MatchCollection mc = re.Matches(this.Editor1.XHTML.ToString());

foreach (Match m in mc)

{

string url=m.Groups["src"].Value;

string filepath=url;

if(url.Substring(0,7).ToLower()=="http://")

{

string KuoZhangMing="."+url.Substring(url.LastIndexOf(".")+1);

string path = HttpContext.Current.Server.MapPath(@"/MLXZ/Uploads/Download/");

string filename=DateTime.Now.ToString("yyyyMMddHHmmss")+KuoZhangMing;

path=path+filename;

filepath=@"/MLXZ/Uploads/Download/"+filename;

WebClient myWebClient = new WebClient();

myWebClient.DownloadFile(url,path);

this.Editor1.Text=this.Editor1.XHTML.ToString().Replace(url,filepath);

}

Pic.Items.Add(new ListItem(filepath,filepath));

}

上面代码实现了提取编辑器中的图片地址,如果图片地址为网上的,则会自动保存到本地.其它是的editor1为一个编辑器CuteEditor
