Powershell DataGridView - 在複選框列中循環查看是否選中

Question

我試圖創建一個PowerShell表單，它將所有進程都轉換爲datagridview（迄今爲止工作正常）。然後，我將每行數據源的額外列添加爲複選框。 然後，我想按下我的表單上的一個按鈕，該按鈕啓動名爲「Do-Grid」的函數，並打算查看該第一列中的哪些複選框已被選中。

這就是我卡住的地方。我無法弄清楚如何循環遍歷每一行/單元格，並查看哪個複選框已被勾選（或具有真值）。

謝謝。

Function Do-Grid{ 

    for($i=0;$i -lt $datagridview1.RowCount;$i++){ 

     if($datagridview1.Rows[$i].Cells['exp'].Value -eq $true) 
     { 
     write-host "cell #$i is checked" 
     #uncheck it 
     #$datagridview1.Rows[$i].Cells['exp'].Value=$false 
     } 
     else  
     { 
     #check it 
     #$datagridview1.Rows[$i].Cells['exp'].Value=$true 
     write-host "cell #$i is not-checked" 
     } 
    }
