如何计算powershell变量中的行数

我有以下powershell查询：

$sql = "select name, lastName, City, Address from Persons"

$TotalPeople = Invoke-Sqlcmd -ServerInstance $ResultsInstance -Database $ResultsDatabase -Query $sql

Write-Output "Total number of people run is $TotalPeople  "

我希望能够计算$TotalPeople变量中的行数。在powershell中是否有这样做的方法？

Invoke sqlCmd返回一个数组

因此，您可以简单地使用

Count

属性

$sql = "select name, lastName, City, Address from Persons"
$TotalPeople = Invoke-Sqlcmd -ServerInstance $ResultsInstance -Database $ResultsDatabase -Query $sql
Write-Output "Total number of people run is "$TotalPeople.count

$TotalPeople.count？：）
