Question

我使用System.Data.SqlClient从SQL中提取数据，并最终将数据集存储到变量中：

$SqlQuery = "select * from my_Table"
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server = $SQLServer; Database = $SQLDBName; Integrated Security = True"
$SqlConnection.Open()

$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.CommandText = $SqlQuery
$SqlCmd.Connection = $SqlConnection

$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd

$amManagedFolders = New-Object System.Data.DataSet
$SqlAdapter.Fill($dataset)

然后，我通过类型为$dataset.Tables[0]

的System.ComponentModel.MarshalByValueComponent访问该表格

我需要能够使用ForEach来遍历该表并将结果存储到CustomPSObject中供以后使用，但是，我不确定要按顺序使用的方法为达到这个。

使用this page我发现以下代码很有帮助。我正在进行SQL查询并生成带有结果的Excel工作簿。

$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)
$SqlConnection.Close()
$DataSetTable = $DataSet.Tables["Table"]
## - Build the Excel column heading:
[Array] $getColumnNames = $DataSetTable.Columns | Select ColumnName
## - Build column header:
[Int] $RowHeader = 1
foreach ($ColH in $getColumnNames)
....
foreach ($rec in $DataSetTable.Rows)
{
foreach ($Coln in $getColumnNames)
{
## - Next line convert cell to be text only:
$xlsSh.Cells.NumberFormat = "@"
## - Populating columns:
$xlsSh.Cells.Item($rowData, $colData) = $rec.$($Coln.ColumnName).ToString()
$ColData++
}
$rowData++; $ColData = 1
}

-Edit，看到你的评论。您可以将the answer改为此问题

使用System.ComponentModel.MarshalByValueComponent
