推荐答案

如果您使用OpenFileDialog选择文件，那么您将获得流，对吗?

因此，您可以将此流http发送到您的Web服务.

请检查以下示例:

Silverlight文件上传 [ ^ ]

注意:不使用任何Web服务都是不可能的.

If you are selecting a file by using OpenFileDialog then you will get the stream, right?

So, you can do http-post this stream to your web service.

Please check this example:

Silverlight File Upload[^]

Note: It''s not possible to do without using any web service.

您将需要在服务器端连接WCF服务.该服务将获取文件信息和字节数组，然后将其存储在本地.

在您的Silverlight应用程序中，您将引用该服务，然后获取图像数据并将其发送.

要获取图像数据，最有可能将其发送到WriteableBitmap中，然后解析Pixels数组...您可以在Silverlight端对其进行格式化并将其向下发送，或将其发送服务器上的原始格式和句柄格式.也许在客户端进行简单压缩，然后在服务器上解压缩并格式化为JPEG/PNG/etc就可以了.

You''ll need to wire in a WCF service at the server side. The service would take the file information and byte array, then store it locally.

In your Silverlight application, you''ll reference the service, then take your image data and send it.

To get to the image data, most likely you''ll send it into a WriteableBitmap and then parse the Pixels array ... you can either format it on the Silverlight side and send it down, or send it raw and handle formatting on the server. Perhaps simple compression in the client, then uncompress and format into JPEG/PNG/etc on the server would be fine.
