Convert MyList(,) of Object to String array with LINQ - arrays

Question

I have a little problem with the performance of one of my applications, basically:
An external system gives me a big structure as an Object(,).
This structure only has an column per row.
MyData(0,0) = 'COL1-ROW1 | COL2-ROW1 | COL3-ROW1'
MyData(1,0) = 'COL1-ROW2 | COL2-ROW2 | COL3-ROW2'
MyData(2,0) = 'COL1-ROW3 | COL2-ROW3 | COL3-ROW3'
MyData(3,0) = 'COL1-ROW4 | COL2-ROW4 | COL3-ROW4'
MyData(0,1) ' Doesn't exists.
There are some method in LINQ to convert this structure to an one dimensional array of strings?
It would be awesome if you could divide by columns, given a specific character.
Something like this:
NewData(0,0) = COL1-ROW1
NewData(0,1) = COL2-ROW1
NewData(0,2) = COL3-ROW1
NewData(1,0) = COL1-ROW2
...
NewData(3,2) = COL3-ROW3

Answer 1

Seems I found the answer from myself; here my solution:
Dim vMyData(1000, 0) As Object
For x = 0 To 1000
vMyData(x, 0) = String.Format("ROW{0}COL1|ROW{0}COL2|ROW{0}COL3|ROW{0}COL4", x)
Next
Dim vQuery = From TempResult In vMyData
Select Value = TempResult.ToString.Split("|")
Dim vMyNewArray As New ArrayList(vQuery.ToArray)
Now; exists some method to trim each value of the Split("|")?
[UPDATE TO THE PREVIOUS QUESTION]:
From TempResult In vMyData Select Value = Array.ConvertAll(TempResult.ToString.Split("|"), Function(vVal) vVal.ToString.Trim)
