Answer 1

   webClient.UploadFile("http://apitest.myserver.com/uploadfile", filePath);
            本地文件 map.jpg传到服务器apitest.myserver.com网站下的uploadfile文件夹下，这里的filepath是写map.jpg 还是 【本地绝对路径+map.jpg】我测试哪个都不对啊，按理说默认是使用post方法，但是却会提示【远程服务器返回错误: (405) 不允许的方法】

Answer 2

WebClient.UploadFile(uriString,"PUT",fileNamePath); try...

Answer 3

写一个服务器端接受页面（推荐ashx），并且调试。贴出你的调试画面。

Answer 4

写一个服务器端接受页面（推荐ashx），并且调试。贴出你的调试画面。不是不需要接受页面吗

Answer 5

直接使用put还不行
我已经开启了webdav服务模块，在IIS7的处理程序映射中搞不清 该设置哪个请求限制 允许put操作。还有没有其他限制？

Answer 6

写一个服务器端接受页面（推荐ashx），并且调试。贴出你的调试画面。不是不需要接受页面吗你写一个6、7行代码的接受页面，不就就能方便自己调试了嘛。
