Request.Form: see difference between multiple form fields with the same name
Posted on 2012-12-21
Does the Asp.Net Request.Form offer any way to see the difference between
<form method="post">
<input type="hidden" name="field" value="a" />
<input type="hidden" name="field" value="a" />
<input type="hidden" name="field" value="a" />
</form>
and
<form method="post">
<input type="hidden" name="field" value="a,a,a" />
</form>
For example is there a way to count how many fields with name="field" have been submitted?
(in Classic ASP that is possible, but I can not find a way to do it in Asp.Net)
<form method="post">
<input type="hidden" name="field" value="a" />
<input type="hidden" name="field" value="a" />
<input type="hidden" name="field" value="a" />
</form>
and
<form method="post">
<input type="hidden" name="field" value="a,a,a" />
</form>

Request.Form returns NameValueCollection. GetValues is a NameValueCollection class method which gives us the requested result.

Hi,
you can go trough Request.Form.AllKeys list and see if there multiple "field" keys found.

dim fieldCount as integer = 0
For Each key As String In Request.Form.AllKeys
if key = "field" then fieldCount= fieldCount+1

In ASP.Net all form fields need to have a unique name so that they can be differentiated from one another. Are you posting to .Net from classic ASP?
You can enumerate like pratima_mcs states. This is much more easy if your posting form is .Net to begin with. A pseudo code example would be something like...

For each form control in someContainer
If control type is input Then
if control.uniqueID ends with 'field' Then
controlCount += 1
End if
End If
End For
