If the client uses multipart/form-datarequest encoding (which is the standard for uploading files) you could retrieve the uploaded file from the Request.Filescollection. For example:
如果客户端使用multipart/form-data请求编码（这是上传文件的标准），您可以从Request.Files集合中检索上传的文件。例如：
protected void Page_Load(object sender, EventArgs e)
{
foreach (HttpPostedFile file in Request.Files)
{
var fileName = Path.GetFileName(file.FileName);
var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName);
file.SaveAs(path);
}
}
or if you know the name used by the client you could directly access it:
或者，如果您知道客户端使用的名称，则可以直接访问它：
HttpPostedFile file = Request.Files["file"];
If on the other hand the client doesn't use a standard encoding for the request you might need to read the file from the Request.InputStream.
另一方面，如果客户端没有对请求使用标准编码，则您可能需要从Request.InputStream.
