[RESOLVED] How to Extract GUIDs out of a string?

[jesus4u]

I am in Vb.NET 2008.

I want to extract or split all the GUIDS out of a string like this:

"331|-1|2||True|0|False|6f85d48a-9219-4a9a-98bf-e6fb2319727c||False/-1|0|3||True|0|False|5f3d89d2-461c-47f8-ace7-4f8e2e37879f||False|"

Here is the code I have and it does not work.

Dim s() As String = Regex.Split("331|-1|2||True|0|False|6f85d48a-9219-4a9a-98bf-e6fb2319727c||False/-1|0|3||True|0|False|5f3d89d2-461c-47f8-ace7-4f8e2e37879f||False|".ToUpper , "^[A-Z0-9]{8}-[A-Z0-9]{4}-[A-Z0-9]{4}-[A-Z0-9]{4}-[A-Z0-9]{12}$")

Output desired:

6f85d48a-9219-4a9a-98bf-e6fb2319727c

5f3d89d2-461c-47f8-ace7-4f8e2e37879f

Would you like them as a string or GUID? You can use the String.Split ("|") to split them up. Trim it first.

Then compare the length i guess. Or see if the string contains a "-"

If you want to convert it to a GUID then you can
Dim g As String
Dim instance As New Guid(g)

and it will throw an exception if not in the right format.

Actually I just got it!

Dim ms As MatchCollection = Regex.Matches(_TreeNode.Parent.ValuePath.ToUpper, "[A-Z0-9]{8}-[A-Z0-9]{4}-[A-Z0-9]{4}-[A-Z0-9]{4}-[A-Z0-9]{12}")
Me.ParentGUID = ms.Item(ms.Count - 1).Value.ToLower '--Get the last item, it is the parent guid.
