的原文：的
我不知道，我明白你的问题100％，但我认为你要上传文件到一个URL，看起来像HTTP：// {服务器名称} / {}控制器/上传？这将被精确地实现像使用Web表单一个正常的文件上传

Original: I am not sure that I understand your question 100%, but I assume that you want to upload a file to a url that looks something like http://{server name}/{Controller}/Upload? This would be implemented exactly like a normal file upload using web forms.

所以，你的控制有一个名为上传操作，看起来与此类似：

So your controller has an action named upload and looks similar to this:

//For MVC ver 2 use:
[HttpPost]
//For MVC ver 1 use:
//[AcceptVerbs(HttpVerbs.Post)] 
public ActionResult Upload()
{
    try
    {
        foreach (HttpPostedFile file in Request.Files)
        {
            //Save to a file
            file.SaveAs(Path.Combine("C:\\File_Store\\", Path.GetFileName(file.FileName)));

            // * OR *
            //Use file.InputStream to access the uploaded file as a stream
            byte[] buffer = new byte[1024];
            int read = file.InputStream.Read(buffer, 0, buffer.Length);
            while (read > 0)
            {
                //do stuff with the buffer
                read = file.InputStream.Read(buffer, 0, buffer.Length);
            }
        }
        return Json(new { Result = "Complete" });
    }
    catch (Exception)
    {
        return Json(new { Result = "Error" });
    }
}

在这种情况下，我回到JSON来表明成功，但你可以改变这如果需要，XML（或与此有关的任何东西）。

In this case I am returning Json to indicate success, but you can change this to xml (or anything for that matter) if needed.
