Concatenating a variable and a string literal without a space in PowerShell
提问by M. Dudley
How can I write a variable to the console without a space after it? There are problems when I try:
如何在没有空格的情况下将变量写入控制台？我尝试时出现问题：
$MyVariable = "Some text"
Write-Host "$MyVariableNOSPACES"
I'd like the following output:
我想要以下输出：
Some textNOSPACES

Another option and possibly the more canonical way is to use curly braces to delineate the name:
另一种选择，可能是更规范的方法是使用花括号来描述名称：
$MyVariable = "Some text"
Write-Host "${MyVariable}NOSPACES"
This is particular handy for paths e.g. ${ProjectDir}Bin\$Config\Images. However, if there is a \after the variable name, that is enough for PowerShell to consider that notpart of the variable name.
这对于路径特别方便，例如${ProjectDir}Bin\$Config\Images. 但是，如果\变量名后面有一个，就足以让 PowerShell 认为它不是变量名的一部分。

You need to wrap the variable in $()
您需要将变量包装在 $()
For example, Write-Host "$($MyVariable)NOSPACES"
例如， Write-Host "$($MyVariable)NOSPACES"

Write-Host $MyVariable"NOSPACES"
Will work, although it looks very odd... I'd go for:
会工作，虽然它看起来很奇怪......我会去：
Write-Host ("{0}NOSPACES" -f $MyVariable)
But that's just me...
但这只是我...

You can also use a back tick `as below:
您还可以使用反勾号`，如下所示：
Write-Host "$MyVariable`NOSPACES"
回答by Dheeraj2006
$Variable1 ='www.google.co.in/'
$Variable1 ='www.google.co.in/'
$Variable2 ='Images'
$Variable2 ='图像'
Write-Output ($Variable1+$Variable2)
写输出（$Variable1+$Variable2）

if speed matters...
如果速度很重要...
$MyVariable = "Some text"
# slow:
(measure-command {foreach ($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
