Sending array data with hidden input field from client side to server side

I have some values that I'm sending with javascript to the server side code via a hidden input field.  This works great.  However, I want to find an elegant way to split the values up on the server side.  What I have below works, but it doesn't seem like a very clean solution. 

Client code

var values = '&approved=1&funded=0&winprob=2';

document.form1.ipHidden.value = values.toString();

Server code

Dim strValues As String = ipHidden.Value.ToString()

Dim strApproved = strValues.Substring(strValues.IndexOf("approved=") + 9, 1)

Dim strFunded = strValues.Substring(strValues.IndexOf("funded=") + 7, 1)

Dim strWinProb = strValues.Substring(strValues.IndexOf("winprob=") + 8, 1)


As you can see I'm passing the values similar to how they'd be passed in a QueryString.  Is there a way to take a string like "strValues = &approved=1&funded=0&winprob=2" and get the values for each key similar to using the QueryString.  ie.  strApproved = strValues.QueryString("approved")

Thanks for any help.

You can split strValues whenever @ character exists

strValues.Split('@') which will return a string array containing 4 items 

    1- Nothing

    2- approved=1

    3- funded=0

    4- winprob=2

And you can assign each string to its specified value in the returned string array

I understand how Split will return a string array, butI still don't understand how to get at each value without looping through the array and testing for the existence of the key I want the value for.  Is the following the best way to get at these values?  Or could the string array be loaded into a SortedList easily?  Then I could just reference the SortedList like strApproved = slList.Item("approved").  But how do I load the SortedList without doing something clunky with the InStr and Substring methods?

Dim strArray() = strValues.Split("&")

For Each strValue As String In strArray

If InStr(strValue, "approved") Then

strApproved = strValue.Substring(9, 1)

ElseIf InStr(strValue, "funded") Then

strFunded = strValue.Substring(7, 1)

ElseIf InStr(strValue, "winprob") Then

strWinProb = strValue.Substring(8, 1)

End If



Thanks for the help.

Perhaps you can try the following code snippet to retrieve the values from the string above.

  Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

        Dim strValues As String = "&approved=1&funded=0&winprob=2"
        Dim strWinProb As String
        Dim strApproved As String
        Dim strFunded As String
        Dim strArray() = strValues.Split("&")
        For Each str1 As String In strArray
            If str1 Is Nothing Or str1 = "" Then
                Continue For
                Dim substrarray() = str1.Split("=")
                Select Case substrarray(0)
                    Case "approved"
                        strApproved = substrarray(1)
                    Case "funded"
                        strFunded = substrarray(1)
                    Case "winprob"
                        strWinProb = substrarray(1)
                End Select
            End If
    End Sub

Passing client side to server side using hidden field

The final output is an html report that can be emailed. Because this is currently being done on the client side, as the raw data grows the load-time grows as well (to the point that has almost become unusable). I’m posting here to see if anyone has any experi...
