正则取图片地址问题？

[wsjrzjp2012]

<meta property="og:image" content="http://192.168.1.100:8080//upload/C/PREW_CIE185944.JPG"/>

GetRegValue("<meta" + @"\s+" + "property=\"og:image\"" + @"\s+" + "content=\"(?<content>[^\"" + @"\<\>" + "]*)\"", jg1)

我这不知道错在那里了，取不到图片地址：http://192.168.1.100:8080//upload/C/PREW_CIE185944.JPG

string productPic = GetRegValue("<meta property=\"og:image\" content=([\\w\\W]*?)/>", jg1);
这方法试了也是不行

string sql=@" <meta property=""og:image"" content=""http://192.168.1.100:8080//upload/C/PREW_CIE185944.JPG""/>";
sql=Regex.Replace(sql,@"\t|\r|\n|\s","");
Regex reg = new Regex(@"\<metaproperty\=""og\:image""content\=""(.*)""\/\>");
string reval = reg.Match(sql).Groups[1].Value;

string temp = @"<meta property=""og:image"" content=""http://192.168.1.100:8080//upload/C/PREW_CIE185944.JPG""/>";
Response.Write(Regex.Match(temp, @"(?<=content=\"")[^""]+(?="")").Value);

你正则太乱了。
