PowerShell回声语句变量在一行中

Question

我正在运行一个脚本，我希望它在最后[成功时]打印一个“statement variable statement”。我尝试了一些方法，但它总是以三行而不是一行的形式返回。前后的回音“”只是为了让打印时更容易阅读，将其隔开，我尝试了有无回音，得到了相同的结果。

$filename = "foo.csv"

    echo ""
    echo "The file" $filename "has been processed."
    echo ""

我明白了：

The file
foo.csv
has been processed.

Answer 1

echo ("The file "+ $filename +" has been processed.")

Answer 2

在powershell中，您可以按如下方式使用写主机：

$filename = "foo.csv"
Write-Host 'The file' $filename 'has been processed.'

-> The file foo.csv has been processed.

Answer 3

如果使用双引号，可以直接在字符串中引用变量，因为它们允许变量展开，而单引号不允许展开。

$filename = "foo.csv"
Write-Output "The file $filename has been processed."

-> The file foo.csv has been processed.

而且，echo实际上只是写入输出的别名，所以我使用了全名。
