![]() 在第一个例子中,是通过拼字符串来得到byte[] data参数值的,对于这种表单显然不行,反过来想想,对于uploadData.aspx这样的程序来说,直接通过网页提交数据,后台所获取到的流是什么样的呢?(在我以前的一篇blog中,曾分析过这个问题:asp无组件上传进度条解决方案),最终的数据如下:

![]() 所以只要拼一个这样的byte[] data数据Post过去,就可以达到同样的效果了。但是一定要注意,对于这种带有文件上传的,其ContentType是不一样的,例如上面的这种,其ContentType为"multipart/form-data; boundary=---------------------------7d429871607fe"。有了ContentType,我们就可以知道boundary(就是上面的"---------------------------7d429871607fe"),知道boundary了我们就可以构造出我们所需要的byte[] data了,最后,不要忘记,把我们构造的ContentType传到WebClient中(例如:webClient.Headers.Add("Content-Type", ContentType);)这样,就可以通过WebClient.UploadData 方法上载文件数据了。
