Select 个基于名称的数组值

Question

我使用以下方法提取了 SQL 实例的一些详细信息：

$SQLInstance1 = Get-DbaInstanceProperty -SqlInstance SQL | Select-Object ComputerName, Name, Value  | Where-Object Name -In ("FullyQualifiedNetName", "Edition", "PhysicalMemory", "Processors", "VersionString", "Collation", "IsClustered", "ResourceLastUpdateDateTime")

将这些值分配给数组输出中的变量的最佳方法是什么：

ComputerName 名称值

SQL版企业版（64位） SQL 物理内存 1571485
SQL 处理器 40
SQL 版本字符串 11.0.7493.4
SQL 排序规则 Latin1_General_CI_AS
SQL IsClustered 为真
SQL ResourceLastUpdateDateTime 24/12/2019 9:58:55 下午
SQL FullyQualifiedNetName PTHSQL13.FMG.local

所以我想从上面分配 $ComputerName = ComputerName、$Edition = Edition 等，然后我可以用它来更新 SQL table $ComputerName

Answer 1

好的。首先，您需要将结果转换为字典，然后使用该属性字典创建一个新对象。

例如：

$dict = @{ }

(Get-DbaInstanceProperty -SqlInstance localhost | Select-Object ComputerName, Name, Value | Where-Object Name -In ("FullyQualifiedNetName", "Edition", "PhysicalMemory", "Processors", "VersionString", "Collation", "IsClustered", "ResourceLastUpdateDateTime")).GetEnumerator() | % { $dict.Add($_.Name, $_.Value) }

New-Object -TypeName PSObject -Property $dict

$result = New-Object -TypeName PSObject -Property $dict

$result.FullyQualifiedNetName

$result.Processors

上面的代码应该打印出 FullyQualifiedNetName 值和 Processors 计数。

Answer 2

Dot Notation 是您的朋友。由于您存储的是序列化的实际对象，因此可以使用 .propertiesname.

引用存储值的属性

[array]SQLInstance1 = Get-DbaInstanceProperty -SqlInstance SQL | Select-Object ComputerName, Name, Value  | Where-Object Name -In ("FullyQualifiedNetName", "Edition", "PhysicalMemory", "Processors", "VersionString", "Collation", "IsClustered", "ResourceLastUpdateDateTime")

($SQLInstance1.ComputerName.Count + $SQLInstance1.Name.Count + $SQLInstance1.Value.Count); $i++){
[pscustomobject]@{
            ComputerName = $($SQLInstance1.ComputerName[$i])
            Name = $($SQLInstance1.Name[$i])
            Value = $($SQLInstance1.Value[$i])

                }
        }
