How can I write a variable to the console without a space after it? There are problems when I try:
$MyVariable = "Some text"
Write-Host "$MyVariableNOSPACES"
I'd like the following output:
Some textNOSPACES

One possibly canonical way is to use curly braces to delineate the name:
$MyVariable = "Some text"
Write-Host "${MyVariable}NOSPACES"
This is particular handy for paths e.g. ${ProjectDir}Bin\$Config\Images. However, if there is a \ after the variable name, that is enough for PowerShell to consider that not part of the variable name.

How can I write this one:
Write-Host "\\"$pc[$i]? I need 2 backslashes before a variable without spaces. This solution has one space between the second backslash and the var value.There should be a param like -nonewlilne for spaces.

"Possibly canonical" Possibly? Do you have a citation or is this just your preference/gut feeling?
You need to wrap the variable in $()
For example, Write-Host "$($MyVariable)NOSPACES"

In my testing this put a space between the variable and the string literal.

This is what I see:
$MyVariable = "Some text" Write-Host "$($MyVariable)NOSPACES" Some textNOSPACESravikanth
What is wrong? imgur.com/a/eLmBtlg Check that. There is no space between the variable text and the string literal.

Ultimately, I found I was inserting spaces through improper syntax, but first I jumped on Keith's answer - and it didn't work. It works if $MyVariable contains a String, but not if it contains an Object with a Property storing the String; ${ObjectVariable.SomeProperty} resolves to nothing This answer works for Object Properties too.
Write-Host $MyVariable"NOSPACES"
Will work, although it looks very odd... I'd go for:
Write-Host ("{0}NOSPACES" -f $MyVariable)
But that's just me...

You can also use a back tick ` as below:
Write-Host "$MyVariable`NOSPACES"

This variant has an advantage that it works also within a command executed from the script (unlike
${MyVariable} and $($MyVariable))

This variant also has the disadvantage that if the character following the backtick matches a special character, it will insert that special character (try
"$MyVariable`nospaces", for example).$Variable1 ='www.google.co.in/'
$Variable2 ='Images'
Write-Output ($Variable1+$Variable2)

Further to the question, this is another simple way to concatenate 2 variables without space. Putting both variables as shown in the above example, the output will be "www.google.co.in/images"
Easiest solution: Write-Host $MyVariable"NOSPACES"

It works, but PowerShell will not let you insert multiple spaces between the variable and the string literal.

Why wouldn't you just move the spaces to the string literal?
Write-Host $MyVariable" NOSPACES"?
T.S.
$MyVariable = "x"... $MyVariable"NOSPACES" --> x NOSPACES. <-- inserts a space. This works --> ($MyVariable"NOSPACES")`TylerH
This repeats one of the solutions from stackoverflow.com/questions/5144110/… from a year prior.
if speed matters...
$MyVariable = "Some text"
# slow:
(measure-command {foreach ($i in 1..1MB) {
$x = "$($MyVariable)NOSPACE"
}}).TotalMilliseconds
# faster:
(measure-command {foreach ($i in 1..1MB) {
$x = "$MyVariable`NOSPACE"
}}).TotalMilliseconds
# even faster:
(measure-command {foreach ($i in 1..1MB) {
$x = [string]::Concat($MyVariable, "NOSPACE")
}}).TotalMilliseconds
# fastest:
(measure-command {foreach ($i in 1..1MB) {
$x = $MyVariable + "NOSPACE"
}}).TotalMilliseconds

$MyVariableN(or another collision) that PS would figure out what you meant. No dice.
