IDE :: String Concatenation Bug?

Any thoughts welcome:
C# - String Concatenation And Threads In .NET?
Oct 18, 2011In VB.net, I tested concatenating 100k strings and found out one thread alone did it in 23 milliseconds. Two threads (each concatenating 50k) then joining the two at the end took 30 milliseconds. Performance wise, it didn't seem beneficial to utilize multiple threads when dealing with only 100k concatenations. Then I tried 3 million string concatenations and two threads each handling 1.5MM always demolished one thread handling all 3 million. I imagine at some point using 3 threads becomes beneficial, then 4, and so on. Is there a more efficient way to concatenate millions of strings in .NET?
fyi, this is the code I wrote:
Imports System.Text
Imports System.Threading
Imports System.IO

Sep 13, 2010Possible Duplicate: The difference between + and & for joining strings in VB.Net.In VB.NET you can use either += or &= to concatenante a string (ignoring using a StringBuilder for this question -- this is directed at a very simple concatenation).
View 2 RepliesArabic In Strings Are Being Disordered After Concatenation?
Aug 20, 2011I'm trying to compose a String from multiple Strings, where some of the Strings may be in Arabic letters, the problem is that when I concatenate them, their order is being messed !!
For example, I have the following Strings:
Ref1
مسكه
2
Left
I want to concatenate them with the same previous order seperated by "-", but instead I get Ref1-مسكه-2-Left, as you can see, 2 is written before مسكه Does anyone know how to fix this problem, because it's really important in my case to have the exact same order, and I don't know where or when I might have these arabic strings, because it's being entered by User.

Concatenation: Getting The Text From Multiple Labels
Apr 13, 2012I am creating a program to simulate a tenpin bowling scoring system, and I'm using labels with the following name structure:
Player1Frame1Ball1, Player1Frame1Ball2, etc..
I have following variables also: CurrentPlayer, CurrentFrame, CurrentBall
I am hoping to use these variables to specify which label I would like to check the value of (the score achieved, placed in the label).
To test my experiments I have been trying to output the score of the first ball in the current frame in a msgbox, but to no success:

Performance Difference Between ToString() And & Concatenation?
Jun 1, 2010When I am concatenating object values together to form a string in VB.NET, is there a difference in performance or a recommended best practice between using the & concat or the + concat with calls to .ToString() on each object?
Example (which is faster or best practice):
Dim result1 As String = 10 & "em"
Dim result2 As String = 10.ToString() + "em"

String Concatenation Won't Work Using Class?
Jun 14, 2012I'm trying to concatenate two properties into one string like so:
public class thing
public property word() as string()
public property count() as integer()
[Code]....
This is what I want, but it doesn't help that its in the debug output...I need to put it into a single string. I've tried using a_thing.count(i).tostring, but it doesnt work. If I look at the arrays individually, they have exactly the contents I want. But I can't concatenate them. Does it have something to do with suppressing the new line that debug.writeline usually creates?

String Concatenation - Problems Caused By Space(s) Within Path/File Name?
Mar 29, 2011I've got a small app which I use to start a 3rd party application. When run from a shortcut the VB app starts the 3rd party app to and when loaded it displays its own file/folder interface, the VB app the closes itself. However, if you open a file in explorer associated with the 3rd party app, the 3rd party application loads and opens the file itself and not the file/open interface.
Uh OK, so what's the problem??The issue is I have changed the file extension associated with the 3rd party app to now use my VB app. I can successfully open files with the app from explorer if there are no spaces in the file or folder path however if there are, the 3rd party app opens and displays a File not found error message and gives the path up to the point where the space then follows.The relevant snippets of code from the app relating to the issue is below, specifically Dim Arguments variable where I am not quite sure how my string cocantenation should be to deal with the value of the variable 'Filename' which may or may not contain spaces.

String Concatenation String + Function Output + String = String + Function Output And No More?
Feb 4, 2010The following output produces a string with no closing xml tag. m_rFlight.Layout = m_rFlight.Layout + "<G3Grid:Spots>" + Me.gvwSpots.LayoutToString() + "</G3Grid:Spots>"
This following code works correctly
m_rFlight.Layout = m_rFlight.Layout + "<G3Grid:Spots>" + Me.gvwSpots.LayoutToString()
m_rFlight.Layout = m_rFlight.Layout + "</G3Grid:Spots>" 'add closing tag
What's going on here, what's the reason the first example isnt working and the second is?
The gvwSpots.LayoutToString() function returns a string.
