我想用JSON Web服務保存Image中的數據,而不保存圖像數據。 但發送圖像字節時不保存。如何在窗口JSON webservie發送或Recive影像電話7如何使用JSON WebService保存數據庫中的圖像WP7
我的web服務:
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public string Register(string emailID, string pwd, string name, string img)
{
ProfileDL _client = new ProfileDL();
_client.Email = emailID;
_client.Password = pwd;
img = img.Replace(' ', '+');
_client.Firstname = name;
_client.Img = Convert.FromBase64String(img);
_client.saveData();
return "Y";
}
WP7 Code:-
//Convert Image to byte code
private void photoChooserTask_Completed(object sender, PhotoResult e)
{
imageBytes = new byte[e.ChosenPhoto.Length];
e.ChosenPhoto.Read(imageBytes, 0, imageBytes.Length);
}
void GetRequestStreamCallbackx(IAsyncResult asynchronousResult)
{
HttpWebRequest webRequest = (HttpWebRequest)asynchronousResult.AsyncState;
// End the stream request operation
Stream postStream = webRequest.EndGetRequestStream(asynchronousResult);
string img = string.Empty;
try
{
img = Convert.ToBase64String(imageBytes);
}
catch { }
// Create the post data
// string postData = "";
var json="";
Dispatcher.BeginInvoke(() => json = "{\"emailID\": " + txtemail.Text.Trim() + ",\"pwd\": " + txtpassword.Text + ",\"name\":" + txtname.Text + ",\"img\": " + img + "}");
byte[] byteArray = Encoding.UTF8.GetBytes(json);
// Add the post data to the web request
try
{
postStream.Write(byteArray, 0, byteArray.Length);
}
catch { }
postStream.Close();
// Start the web request
webRequest.BeginGetResponse(new AsyncCallback(GetResponseCallback), webRequest);
}
有任何事情錯在我的代碼。請幫忙...
感謝先生,我有變化的代碼,根據你,但返回錯誤「AsyncWaitHandle =‘asynchronousResult.AsyncWaitHandle’扔類型的異常的‘System.NotSupportedException’」 – 2012-03-29 10:52:46
確定,然後只是嘗試獲得JSON值之前做孔請求!這應該解決問題! – 2012-03-29 11:17:59
