我一直在开发一个 Windows Phone 应用程序，该应用程序将图像和文本放在一起并将它们上传到服务器。
调试应用程序时出现问题。这个问题似乎是技术性的。我真的不知道该怎么做。
这就是为什么我想在这里发布这个问题。如果你们中的某个人可以帮助解决这个问题，我将非常感谢这里提供给我的帮助。
我非常感谢这里所做的工作。没有你们，我们真的不会走到这一步。您让我们有机会从错误中吸取教训。
再次感谢。
请检查我的代码是否需要任何调整。
这是我在模拟器上调试时弹出的错误消息：
未能分配给属性“System.Windows.Controls.Primitives.ButtonBase.Click”。[行：41 位置：250]
这是我的第一篇文章，所以我不能发布图片，很遗憾。
我很欣赏这里所做的工作。
private void button3_Click(object sender, PhotoResult e)
{
if (e.TaskResult == TaskResult.OK)
//void photoChooserTask_Completed(object sender, PhotoResult e)
//{
{
System.Windows.Media.Imaging.BitmapImage bmp = new System.Windows.Media.Imaging.BitmapImage();
bmp.SetSource(e.ChosenPhoto);
image1.Source = bmp;
byte[] sbytedata = ReadToEnd(e.ChosenPhoto);
string s = sbytedata.ToString();
WebClient wc = new WebClient();
Uri u = new Uri("ftp://ftp.icupload.cs201.com/icupload.cs201.com/images/");
wc.OpenWriteCompleted += new OpenWriteCompletedEventHandler(wc_OpenWriteCompleted);
wc.OpenWriteAsync(u, "POST", sbytedata);
}
}
public static void wc_OpenWriteCompleted(object sender, OpenWriteCompletedEventArgs e)
{
if (e.Error == null)
{
object[] objArr = e.UserState as object[];
byte[] fileContent = e.UserState as byte[];
Stream outputStream = e.Result;
outputStream.Write(fileContent, 0, fileContent.Length);
outputStream.Flush();
outputStream.Close();
string s = e.Result.ToString(); ;
}
}
public static byte[] ReadToEnd(System.IO.Stream stream)
{
long originalPosition = stream.Position;
stream.Position = 0;
try
{
byte[] readBuffer = new byte[4096];
int totalBytesRead = 0;
int bytesRead;
while ((bytesRead = stream.Read(readBuffer, totalBytesRead, readBuffer.Length - totalBytesRead)) > 0)
{
totalBytesRead += bytesRead;
if (totalBytesRead == readBuffer.Length)
{
int nextByte = stream.ReadByte();
if (nextByte != -1)
{
byte[] temp = new byte[readBuffer.Length * 2];
Buffer.BlockCopy(readBuffer, 0, temp, 0, readBuffer.Length);
Buffer.SetByte(temp, totalBytesRead, (byte)nextByte);
readBuffer = temp;
totalBytesRead++;
}

这是第 41 行...位置 252 是“Click = myButton3_Click”

在您在这里提到的所有更改之后，我仍然得到三个相同的错误。
错误 2“System.Windows.RoutedEventArgs”不包含“ChosenPhoto”的定义，并且找不到接受“System.Windows.RoutedEventArgs”类型的第一个参数的扩展方法“ChosenPhoto”（您是否缺少 using 指令或程序集参考？） C:\Users\Yaseen\Desktop\IC Final\Phone Application\MainPage.xaml.cs 107 41 Phone Application
这些直接出现在 button3 语法之后
