如何清除NameValue集合发布的值，Request.Form [" Key"] [英] How to Clear NameValue collection posted values , Request.Form["Key"]

问题描述

我使用Page.Post方法使用Namevaluecollection将值发布到另一个页面



来自目标页面我正在检索值为Request.Form [Key ]

检索后我无法清除那些项目。

Request.Form.Clear（）将错误视为只读，因此我只得到以前的值每个新请求





请向我建议明确值



< br $> b $ b



谢谢。

解决方案

试试这个

 [HttpPost] 
 public ActionResult Create（FormCollection collection）
 {
 try 
 {
 string value = collection [0] ; 
 //放一个debuge看价值
  collection.Clear（）;  
 string value2 = collection [0]; 
 //再看清楚
后的值2 ---------------------------------- ----------------------- 

如果你想根据类型删除servervariables数据使用这个一个

I have used Page.Post Method to post values to another page using Namevaluecollection

from the destination page i am retrieving values as Request.Form["Key"]
after retrieving i am unable to clear that items.
Request.Form.Clear() giving error as read only , because of this i am getting previous values only for every new request


please suggest to me clear values




Thank you .

解决方案

Try this one

        public ActionResult Create(FormCollection collection)
        {
            try
            {
               string value = collection[0];
               //Put a debuge see the value 
                collection.Clear();
            string value2 = collection[0];
             //Again see the value 2after clear
---------------------------------------------------------
