如何获取PageData？的网址？当前pagedata url is PageData["LogoUrl"] = "/images/logo.png";但我需要将网址更改为存储图片的@imageSrc：
MemoryStream ms = new MemoryStream();
ms.Write(logo.PicImgData, 0, logo.PicImgData.Length);
string imageBase64 = Convert.ToBase64String(ms.ToArray());
var imageSrc = string.Format("data:image/jpeg;base64,{0}", imageBase64);
PageData["LogoUrl"] = "/images/logo.png";
//ive tried with PageData["LogoUrl"] = "@imageSrc"; but it doesnt work
