C# 将文件从Windows Mobile设备传输到…任何位置

我似乎找不到解决这个问题的办法。我正试图让WindowsMobile6上的CompactFramework应用程序能够将本地文件系统上的文件移动到另一个系统

以下是我知道的解决方案：

• FTP-这是大多数的问题 这些API使用起来非常昂贵

• HTTP PUT-据我所知，我不能将匿名PUT与IIS7一起使用，这就是系统正在运行的web服务器。（一个极端的解决方法是使用不同的web服务器放置文件，并让其他系统将其传输到IIS系统）

• Windows共享-我需要对共享进行身份验证，但我还没有看到通过Windows mobile传递此身份验证的方法

最后一种方法是要求将设备置于摇篮中以传输这些文件，但我真的希望能够通过无线方式传输这些文件。

• FTP：定义“太贵”。你是指性能、字节开销还是美元成本

• HTTP:IIS7当然支持托管或访问。你可以很容易地使用这两种方法来上传数据

• Windows共享只需要您这样做，但并不十分复杂

我最终只是通过一个PHP脚本将信息传递给web服务器

上面提供的选项不适合我的情况

以下是要点。我有一些代码，里面有进度条、各种检查和处理程序，与发送文件无关，但我相信您可以选择它。我已经从C#和PHP中删除了我的身份验证代码，但是如果有必要的话，您也可以使用自己的身份验证代码

在C#中：

在PHP中（为了您的利益进行了彻底的评论！）：

如果你能把你是怎么做到的，我会+1这个。你是如何在Mobile6上运行PHP的？我只是编写了一个PHP脚本，就像你编写表单处理程序一样。我通过HTTP请求将数据作为字节传递给PHP脚本，其中一个字段是filedata作为字节。唯一的缺点是POST字段的大小限制，这是由web服务器设置的。IIRC Apache默认为20MB。如果这仍然太模糊，我可以挖掘代码-让我知道！我对PHP一无所知。如果这是C#或者甚至是C，我就能猜出来。我已经有了PHP食谱，但其中的代码对我来说仍然是巫毒。用一些示例代码更新了我的答案。我之前的评论是我在切换到这个方法之前尝试的老方法。我一次传递的数据较少，但对我来说似乎是可靠的。
/*
 * Here's the short+sweet about how I'm doing this
 * 1) Copy the file from mobile device to web server by querying PHP script with paramaters for each line
 * 2) PHP script checks 1) If we got the whole data file 2) If this is a duplicate data file
 * 3) If it is a duplicate, or we didn't get the whole thing, it goes away. The mobile 
 *    device will hang on to it's data file in the first case (if it's duplicate it deletes it)
 *    to be tried again later
 * 4) The server will then process the data files using a scheduled task/cron job at an appropriate time
