獲取和插入文本域值到數據庫

Question

我的代碼是：

 @{ 
    var updatedabout= Request.Form["updateabout"]; 
     var db = Database.Open("database3"); 
if (isPost) { 
     var update = db.QuerySingle("UPDATE users SET about = @0 WHERE [E-mail] = @1",updatedabout,WebSecurity.CurrentUserName); 
}} 

<form class="horizontal" action="" method="POST"> 
    <textarea id="updateabout" name="updateabout" rows="5">example</textarea> 
<button type="submit"> 
</form> 

我想提出什麼用戶在文本區域到數據庫中寫道。但我不能得到它的工作。上面的代碼是我迄今爲止所擁有的。

Request.Form["updateabout"]; gets value from query string but in your case you have a text area. If you are using javascript try to use 
var updatedabout=document.getElementById('updatedabout').value;
