1，开启WebCLient访问

2，设置iis和物理文件夹匿名可写入

3，上传路径需要带文件名http://xxx/FileLoad/xxx.jpg

4, iis设置允许PUT动作

服务端是没有问题的，我感觉是请求头有问题，可看了很久没看出来

·405 - 用来访问本页面的 HTTP 谓词不被允许（方法不被允许）
---------------------------

检查这句：httpReq.Method = Convert.ToString(Method.POST);
[/Quote]

public enum Method
{
GET, POST, PUT, DELETE
}

这个是代码，
