从字节到位图c＃

Question

我想将字节转换为位图这里是我的代码，代码是关于从移动设备接收图像并上传到远程服务器：sql server：这是实现以下界面的函数：

public wsSQLResult CreateImage(Stream JSONdataStream) { 
    wsSQLResult result = new wsSQLResult();
    StreamReader reader = new StreamReader(JSONdataStream);
    string JSONdata = reader.ReadToEnd();

    // ..then convert the string into a single "wsCustomer" record.
    JavaScriptSerializer jss = new JavaScriptSerializer();
    wsClass1 cust = jss.Deserialize<wsClass1>(JSONdata);
    if (cust == null)
    {
        result.message = "Unable to deserialize the JSON data.";
        return result;
    }

    pictureDataContext dc = new pictureDataContext();
    fff  user = (from p
                 in dc.fff
                 where (p.id == cust.getid)
                 select p).FirstOrDefault();
    if (user == null)
    {
        byte[] toDecodeByte = Convert.FromBase64String(cust.getpic);

        UploadDocument( toDecodeByte );
        fff newCustomer = new fff()
            {
                id = cust.getid,
                title = cust.gettitle,
                picture = toDecodeByte
            };

        dc.fff.InsertOnSubmit(newCustomer);
        dc.SubmitChanges();

        result.message = "thanks for regestring you may now login";
        return result;
    }

    result.message = "thanks for regestring you may now logijj";
    return result;
}

这里是界面请任何帮助和thnkx很多：

 [OperationContract]
 [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, UriTemplate = "Image", BodyStyle = WebMessageBodyStyle.Wrapped)]
 wsSQLResult CreateImage(Stream JSONdataStream);

我很乐意为你提供帮助。
