Conerting String into Collection

[apurvaG]

Hi All,

Can I use "DirectCast " or "Ctype" to convert a string into NameValueCollec tion in VB.Net?

Example I want to convert the string "a=200&b=30 0" to NameValueCollec tion class using inbuilt method.

Don't want to go for split option.

Please let me know ASAP

No.
Split would be the prefered method. If there were a method, it would probably use Split().

I provided a method for this in the following thread:

It still relies on the Split() function, however, as far as your procedural code goes, it might be a little clearer. I built a class called NameValueCollec tionEx that takes a string in the format you specified after which it functions as if it were a regular NameValueCollec tion object...with the exception that you can then return all the items in the collection as another data string.

[Code=vbnet]Dim oNVC As New NameValueCollec tionEx("Value1= 1&Value2=2&Valu e3=3")

'You can then reference items in the collection like:
Dim Val1 As String = oNVC("Value1")
Dim Val2 As String = oNVC("Value2")
Dim Val3 As String = oNVC("Value3")

'Viewing items in the collection as a NameValue string:
Dim sOut As String = oNVC.DataString
'Output would be
' "Value1=New Value&Value2=2& Value3=3"

'Modifying items
oNVC("Value1") = "New Value"

'Removing items:
oNVC.Item("Valu e2").Remove
Dim sOut As String = oNVC.DataString
' Output would be
' "Value1=New Value&Value3=3"

'Adding items:
oNVC.Add("Value 1", "FirstItem" )
oNVC.Add("Value 2", "SecondItem ")
oNVC.Add("Value 3", "ThirdItem)[/Code]
