Request.Params 和 Request.Form 什么时候不同? [英] When do Request.Params and Request.Form differ?

问题描述

我最近遇到了一个问题，如果使用 Request.Form 访问，则值为 null，但如果使用 Request.Params 检索则很好.这些方法之间有什么区别可能会导致这种情况?

I recently encountered a problem where a value was null if accessed with Request.Form but fine if retrieved with Request.Params. What are the differences between these methods that could cause this?

推荐答案

Request.Form 只包含通过表单发布的变量，而 Request.Params 包含发布的表单变量和指定为 URL 参数的 get 变量.

Request.Form only includes variables posted through a form, while Request.Params includes both posted form variables and get variables specified as URL parameters.
