如何在Powershell中的其他字符串中插入多行字符串？

$FailedTests不是字符串，而是其他某种对象。您的代码目前是这样的：

$FailedTests = [pscustomobject]@{ Name = "Test1"},[pscustomobject]@{ Name = "Test2"}

#I had to use `Format-List *` to output the sample-objects in the same format as your objects.
#The default format are diferent between different types of objects

"+++"
$FailedTests | Format-List *
"+++"

$Text = "
Summary
----------
$FailedTests
"
$Text
"+++"

输出：

+++


Name : Test1

Name : Test2



+++

Summary
----------


+++

对象ToString()不输出任何东西。最简单的解决方案是| Out-String将控制台中获得的格式转换为字符串。这将需要一个子表达式$()。前任：

$FailedTests = [pscustomobject]@{ Name = "Test1"},[pscustomobject]@{ Name = "Test2"}

"+++"
$FailedTests | Format-List *
"+++"

$Text = "
Summary
----------
$($FailedTests | Format-List * | Out-String)
"
$Text
"+++"

输出：

+++


Name : Test1

Name : Test2



+++

Summary
----------


Name : Test1

Name : Test2





+++
