目前我有一个尖锐的应用程序(客户端应用程序)和一个写PHP的Web应用程序.我想在客户端执行特定操作时传输一些文件.这是将文件上传到php服务器的客户端代码..

private void button1_Click(object sender, EventArgs e)
{
    System.Net.WebClient Client = new System.Net.WebClient();

    Client.Headers.Add("Content-Type", "binary/octet-stream");

    byte[] result = Client.UploadFile("http://localhost/project1/upload.php", "POST",
                                      @"C:\test\a.jpg");

    string s = System.Text.Encoding.UTF8.GetString(result, 0, result.Length); 
}

这是用于移动文件的upload.php文件..

$uploads_dir = './files/'; //Directory to save the file that comes from client application.
foreach ($_FILES["pictures"]["error"] as $key => $error) {
  if ($error == UPLOAD_ERR_OK) {
     $tmp_name = $_FILES["pictures"]["tmp_name"][$key];
     $name = $_FILES["pictures"]["name"][$key];
     move_uploaded_file($tmp_name, "$uploads_dir/$name");
 }

我没有从上面的代码中得到任何错误.但它似乎没有起作用.为什么？我错过了什么吗？
