本文介绍了一种手机端通过按钮触发图片选择并上传至服务器的方法，使用了PhotoChooserTask组件来实现图片选取，并通过WebClient进行图片上传。服务端采用ASP.NET接收上传的图片并保存至指定路径。

1、手机端
private void btnUploadPic_Click(object sender, RoutedEventArgs e)
{
PhotoChooserTask pct = new PhotoChooserTask();
pct.ShowCamera = true;
pct.Completed += new EventHandler<PhotoResult>(pct_Completed);
pct.Show();
}

void pct_Completed(object sender, PhotoResult e)
{
if (e.TaskResult == TaskResult.OK)
{
WebClient wc = new WebClient();
wc.OpenWriteCompleted += new OpenWriteCompletedEventHandler(wc_OpenWriteCompleted);
wc.WriteStreamClosed += new WriteStreamClosedEventHandler(wc_WriteStreamClosed);
wc.OpenWriteAsync(new Uri("http://127.0.0.1:21299/MyNoteWeb/ashx/UpLoadImg.ashx"), "POST", e.ChosenPhoto);
}

}

void wc_WriteStreamClosed(object sender, WriteStreamClosedEventArgs e)
{
if (e.Error == null)
{
MessageBox.Show("上传成功");
}
else
{
MessageBox.Show("上传失败");
}
}

void wc_OpenWriteCompleted(object sender, OpenWriteCompletedEventArgs e)
{
if (e.Error == null)
{
using (Stream photoStream = (Stream)e.UserState)
{
photoStream.CopyTo(e.Result);
e.Result.Close();
}
}
}
2、(asp.net)服务端：
public void ProcessRequest (HttpContext context) {
context.Response.ContentType = "text/html";
upLoad(context);
context.Response.End();
}
