我是 Windows 开发的新手。我尝试了很多将图像上传到服务器,但我无法这样做。
如果有人可以帮助我,请在下面查看我的代码
void uploadphoto()
{
WebClient webClient1 = new WebClient();
webClient1.DownloadStringCompleted += new DownloadStringCompletedEventHandler(webClient1_DownloadStringCompleted);
webClient1.DownloadStringAsync(new Uri("Web Service"));
}
void webClient1_DownloadStringCompleted(object sender, DownloadStringCompletedEventArgs e)
{
var rootobject1 = JsonConvert.DeserializeObject<RootObject1>(e.Result);
int error = rootobject1.response.errorFlag;
string message = rootobject1.response.msg;
if (error == 0)
{
MessageBox.Show(message);
}
else
{
MessageBox.Show(message);
}
}
public class Response1
{
public int errorFlag { get; set; }
public string msg { get; set; }
public List<string> uploadedImageNames { get; set; }
}
public class RootObject1
{
public Response1 response { get; set; }
}
我正在使用下面的代码来选择图像:
private void ImageUpload(object sender, RoutedEventArgs e)
{
//MessageBoxResult mb = MessageBox.Show("Select the mode of uploading the picture", "", MessageBoxButton.OKCancel);
Popup popup = new Popup();
photoSelection photo = new photoSelection();
popup.Child = photo;
popup.IsOpen = true;
photo.camera.Click += (s, args) =>
{
photoCameraCapture.Show();
popup.IsOpen = false;
};
photo.library.Click += (s, args) =>
{
photoChooserTask.Show();
popup.IsOpen = false;
};
}
我正在使用这些代码为 Windows Phone 8 开发应用程序。我正在使用 Json.Net。请帮帮我。提前谢谢。
编辑
private void photoChooserTask_Completed(object sender, PhotoResult e)
{
BitmapImage image = new BitmapImage();
image.SetSource(e.ChosenPhoto);
this.imageTribute.Source = image;
byte[] bytearray = null;
using (MemoryStream ms = new MemoryStream())
{
if (imageTribute.Source == null)
{
}
else
{
WriteableBitmap wbitmp = new WriteableBitmap((BitmapImage)imageTribute.Source);
wbitmp.SaveJpeg(ms, 40, 40, 0, 82);
bytearray = ms.ToArray();
}
}
strimage = Convert.ToBase64String(bytearray);
}
我正在使用此代码选择并转换为 base64,然后将其传递给 Web 服务。
