asp.net request.form

问题

public ActionResult DisplayCustomer()
{
    Customer objCustomer = new Customer();

    objCustomer.Id = Convert.ToInt16(Request.Form["Customerid"]);
    objCustomer.CustomerCode = Request.Form["code"];
    objCustomer.Amount = Convert.ToDouble(Request.Form["amount"]);
    return View(objCustomer);
}

This is my action in controller(MVC 2 aspx):

<form action="DisplayCustomer" method="post">
    Customer id:-
    <input type="text" id="Customerid" /><br />
    Customer Code:-
    <input type="text" id="code" /><br />
    Customer amount:-
    <input type="text" id="amount" /><br />
    <input type="submit" value="click here" />
</form>

This is the view. When someone hit the submit button it is directed to a new page:

<div>
   <b> ID</b> <%= Model.Id %><br />
   <b> Code </b><%=Model.CustomerCode %><br />
   <b> Amount</b> <%=Model.Amount %><br />
</div>

I always get 0 in Id and Amount while blank in CustomerCode.

Any clue? Why this is happening? What is wrong?

回答1:

Your issue here is that you set the id, and not the name. Set the name to get the post back value. Eg:

<input type="text" name="Customerid" />
