我想在(Asp.Net的圖像控件)客戶端顯示圖像(.jpeg)。這段代碼有什麼問題?使用WCF Rest服務顯示圖像
我的休息服務代碼如下,其中我從數據庫中獲取ImagePath。
public Stream getImage(string width, string height)
{
int iRecordid = 1;
var q = from c in db.TblNames
where c.RecordId == iRecordid
select new { c.ImgName, c.ImgPath };
foreach (var obj1 in q)
{
sImageName = obj1.ImgName;
sImagePath = obj1.ImgPath;
}
MemoryStream ms = new MemoryStream();
ms.Position = 0;
return ms;
}
,我使用在客戶端該服務就像
public void getImage()
{
string url = @"http://localhost:50353/CustomerService.svc/getImage/100/200";
var service = new ServiceReference(url);
WebClient wc = new WebClient();
byte[] res1 = wc.DownloadData(url);
Stream res2 = new MemoryStream(res1);
DataContractJsonSerializer res3 = new DataContractJsonSerializer(typeof(ImageMap));
string ss = res3.ReadObject(res2).ToString();
Image1.ImageUrl = ss;
}
我收到錯誤,如
出現錯誤反序列化類型的System.Web.UI的對象。 WebControls.ImageMap。遇到意外字符'ÿ'。
至於我對WCF休息服務的新手。 – Sheeba 2015-02-07 05:44:06
