Get published value in C # ASP.NET

Question

I have a dynamic form that allows me to dynamically add many fields,

I know how to get the value of a single field in aspnet using: Request.Form ["myField"], but here I have more fields and I don’t know the count of these fields, since they are dynamic

the name of the fields is "orders []"

Example:

<form> <input type="text" name="orders[]" value="order1" /> <input type="text" name="orders[]" value="order2" /> <input type="text" name="orders[]" value="order3" /> </form> 

In php, I get the values ​​as an array, referring to $_POST['orders'] ;

Example:

 $orders = $_POST['orders']; foreach($orders as $order){ //execute ... } 

how to do it in c #?

Answer 1

Use Request.Form.GetValues.

Request.Form is a NameValueCollection , an object that can store a collection of elements under the same key, and ToString displays values ​​in CSV format.

Markup:

 <input type="text" name="postField[]" /> <input type="text" name="postField[]" /> <input type="text" name="postField[]" /> <input type="text" name="postField[]" /> <asp:Button Text="text" runat="server" OnClick="ClickEv" /> 

Code behind:

 protected void ClickEv(object sender, EventArgs e) { var postedValues = Request.Form.GetValues("postField[]"); foreach (var value in postedValues) { } } 

Answer 2

You would use Request.Form[] . Or, if your form and fields have runat="server" and identifiers, you can simply use the identifier in the code and the .Text() method to access its value.

Answer 3

You can access everything that is sent back to the server using the Request object.

 Request.Form.Items 

This is the collection that will contain the item you are looking for.
