将控制台应用程序的json输出转换为PowerShell对象

Question

Suppose I have a foo.exe console app that returns some json, and I want to turn that into a PowerShell object.

I was hoping to simply write:

$o = foo.exe | ConvertFrom-Json

But this doesn't work because the output of the console app is treated as an Array instead of a string. I can instead write:

$o = ([string]foo.exe) | ConvertFrom-Json

which feels dirtier than I was hoping.

Question : can I do better than what I have above to get a PowerShell object out of the output of a console app?

Answer 1

作为选择：

$o = foo.exe | Out-String | ConvertFrom-Json
