How to cut a string? [Resolved]

I have a string of characters.

Eg. "Microsoft Visual Basic .NET"

Is there anyway or pre-defined function to cut the string into smaller groups, that will contain only a particular characters of the string?

Eg: After cutting, it becomes
"Microsoft" or
"Visual" or
"Basic" or
".NET"

One easy way would be using Split.

VB Code:

Dim str as String="Microsoft Visual Basic .NET"
Dim SPstr() as String=str.Split(" ")

Split is more flexible than just splitting by a charachter.

Easy:

VB Code:

Dim myString As String
        Dim myArrayOfStrings() As String
        Dim i As Integer
        myString = "Microsoft Visual Basic .NET"
        myArrayOfStrings = myString.Split(" ")
 
        For i = 0 To myArrayOfStrings.GetUpperBound(0)
            MessageBox.Show(myArrayOfStrings(i).ToString())
        Next

You may have this as third option ! Use StringBuilder as follow :

VB Code:

Dim Strbuilder As New System.Text.StringBuilder()

Well , if you read more about StringBuilder , you will know how much efficient it is . anyways I came up with another way though .

VB Code:

Dim b As System.Text.RegularExpressions.Regex

Please dont confuse the guy with Regex. Lets try with simpler ones.

hehe , he's not even responding . We just try to give him as much possible ways since .NET offer them apparently .;)

What I am trying to say is that the code you give:
Dim Strbuilder As New System.Text.StringBuilder()
or
Dim b As System.Text.RegularExpressions.Regex

doesn't show him how to split a string. As a matter of fact it was confusing to me and I know what they are. It didn't help him is what I was saying. The full code on how to use them would be better, not just a declaration statement.

The stringbuilder class wouldn't be more efficient for this case. The stringbuilder class would be more efficient if you were building strings because it it allocates more memory when it needs it, and doesn't create a whole new address space in memory and copy the contents over to it when you add text to it.

When your splitting a string up, there is no way to get around of producing new strings in memory if you want them assigned to variables (or an array). Whether you do it with the string class, stringbuilder class, or through regular expressions, your code will still have to allocate new string variables in memory if your going to assign them to new variables.

I like this part ! exactly what I'w going to explain earlier .

about the way I posted the code hmm , I just wanted to give him another option although I'm sure he'll go for the first post though ..lol .:D

I can SPLIT the string now. Thank you.
