Dim invoiceList As New List(Of Invoice)

Is it from a sight of resources reasonable to use a StringBuilder already to concat two strings or is there a minimum concatenation operations that makes the StringBuilder efficient?

I'm hoping to improve the performance of the below as well as return the GUID of each user.
I've converted and modified the code found here for searching through groups recursively to get all the members and their details and adding them to a class collection. However I also need to capture the user's managers details so I'm calling the AD twice for each user. This doesn't seem efficient as many of the users will have the same manager. It would seem logical to get the distinct manager details from the collection class and call only these, then replace them wherever they occur in the collection.
I'd also like to be able to get the user's GUID, I've tried accessing it directly as a property of the collection, but it doesn't return anything.
I'm using vs2005 and .Net 2.0
Public Class ADCLass
''' <summary>
''' Calls recursive function to return users in group

I am using replace function to replace a character in the file
sw.WriteLine(Regex.Replace(strLine, "\", Chr(13)))
This code is working fine, but now I want to replace two times and I want to use the replace function twice. Something like this, but it is not working . Can anyone tell me how to use Replace function multiple times?
sw.WriteLine(Regex.Replace(strLine, "\", Chr(13)).Replace(strLine, Chr(13), ""))

I need to find several hrefs in html like this:
<table>
<tr><td><a href="url1">link1</a></td>
<td><a href="url2"><img src="image.jpg" /></a></td>
</tr>
</table>
Once found I need to add (replace) to each href something like this:
?ID=1
therefore the html should turn out like this:
<table>
<tr><td><a href="url1?ID=1">link1</a></td>
<td><a href="url2?ID=1"><img src="image.jpg" /></a></td>
</tr>
</table>

I'm creating a method to replace variables in strings, I'm going to share an example of how I'm replacing values and can see short falls in how what I'm doing. Here's a stripped down example of what I'm doing. It replaces a variable with the date specified, so %today(-1) would give me yesterday, %today(2) would give me two days from now.

The code below replaces if it finds a given string from the list of contractions with its equivelant from the list of word-contractions. E.g., if it finds 'll it will replace it with Will. The code words but whtn it comes to let's it will replace it with let is.
'remove panctuation and contractions first
Dim contractions As List(Of String) = New List(Of String)(New String() _

I'm populating a datagridview from a database where all the data has had apostrophes and quotation marks stripped out and replaced with ASCII values; now I want to replace them back. Since the user can perform a variety of queries that are all displayed in the same table, any column might contain text fields.

First it might sound like an ordinary task but keep reading it isn't. I can't figure out how to find a phrase in a text file, and replace it with something else. Tried lots of things but always ending up with empty hands.
Suppose there's a text file in this order:
valueabc=6000.0000
valuettt=200.0000
valuexyz=7000.0000
I want to;
1) Find the phrase (e.g. valueabc) by scanning the whole text,
2) Replace the number that starts after "=" and ends before ".", namely "6000" in the middle with any number value i want.
I don't need the parts before "=" and after ".", only the number in the middle.

Basically, I'm trying to do some string manipulation to edit directories. I found some code to try and edit the directories, but when I use it it doesn't recognise 'right' as being a function and only recognises it as a right property, thus producing an error.
I was wondering if there's something I haven't imported or if perhaps 'right' is an obsolete function that was used in VB6 but replaced with something. The code I have is as follows:

I have a VB .NET String. How can I search that string for a character string and replace it with another string?
For example:
Dim rValue As
String = sproc.ExecuteScalar()
' rValue now has the XML string <indracio fire height=23, width - 6>
/* This is the string that I want to search. Replace the words "indracio fire" with the word "lucion time"
How can I search this string for the words "indracio fire" , and replace with the word "lucion time" ?

I don't use VB.Net very much, still mostly do VB6, but I am doing this project in .Net. I have a huge string of data, 168 Mb that I stream in from a file to a string variable. Then I have to perform a number of replacements on it before using the data to compile statistics. Because of the nature of the data, I can't break this up into smaller strings.
The problem is that I get a system out of memory error after a few replacements.
I've used both Replace(x,y,z) and X.Replace(y,z). The second one gets a little farther in the code before it crashes, but they both crash.
When I run it in the IDE, the IDE is using about 130 Mb of RAM, the Exe of the app is running about 350 Mb, and one svchost.exe runs about 300 Mb
Other than that there are no major RAM uses going on. The PC has an i7 980x cpu with 12 GB of RAM.

Update: I didn't make it clear but I meant this to be a question about where/how I would use a function to return a list of strings when I'm trying to just work with classes.I have a class called Account.
I have data access class called AccountDAO.I have various functions that return lists of objects like GetAllAccounts, GetAccountByID etc.I want to populate a drop down list with just the account names and nothing else. It's proving rather slow when using lists of objects and databinding them to the dropdownlist.
I feel like I should be using a simple "Select Account_Name From blah" type statement and returning a list of strings but I don't know how to work this into my class and data access class.

Say I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members.Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join function?

I am trying to perform calculations on Regex substrings. I would like to do something like (see $2)
lblResult.Text = reg_exp.Replace(txtInput.Text, "$1" & "$2" * 0.039 & "$3" & "$4" & "$5")
I can only do this like:
For Each RxMatch In reg_exp.Matches(Me.txtInput.Text)
Me.lblResult.Text = Me.lblResult.Text & _
RxMatch.Groups.Item(1).ToString & _
Math.Round(CDbl(RxMatch.Groups.Item(2).ToString) * 0.03937, 4) & _
