Question

以下脚本给出了重复的结果，请您告诉我这个脚本中的错误在哪里？在输出中，如果您看到myserver2有重复的条目。

Get-Content "C:\test\computers.txt" | ForEach-Object { $_.TrimEnd() } | ForEach-Object {
    $value += Invoke-Command -Computer $_ -ScriptBlock {
        Param($computer)

        # Connect to SQL and query data, extract data to SQL Adapter
        $SqlQuery = "xp_fixeddrives"
        $SqlConnection = New-Object System.Data.SqlClient.SqlConnection
        $SqlConnection.ConnectionString = "Data Source=$computer;Initial Catalog='Secaudit';Integrated Security = True";
        $SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter($SqlQuery, $Sqlconnection)

        $mdtable = New-Object System.Data.Dataset
        $nRecs = $SqlAdapter.Fill($mdtable)
        $nRecs | Out-Null
        $mdtable.Tables[0]

        for ($i=0; $i -lt $mdtable.tables.count; $i++) {
            $res = $mdtable.Tables[$i]
        }

        $res
    } -ArgumentList $_ -Credential $cred
}

$value

输出（我更改了服务器名称）：
