public void xTimesMyField(int x) {  
MyField=x;  
}  
}  
'@  
for( $i=1;$i -le 10;++$i){  
$object = New-Object MyObject2;  
$object.xTimesMyField($i);

You can’t remove elements from a .NET Array object. You can either use another type of collection (such as an ArrayList), or you can filter the elements and assign them to a new array object (even if it’s in the same variable.) For example:

```
$arr = $arr | Where-Object { $_.MyField -ne 'SomeValue' }
```

You can do some funky stuff with multiple assignment and recursion to remove an element.

Removing based on what the element is.

```
`
function remove-item-list ($item,[array]$chckd_list=@(),[array]$list=(throw"the item $item was not in the list"))
{ if ($list.length -lt 1 ) { throw "the item $item was not in the list" }

$check\_item,$temp\_list=$list  
if ($check\_item -eq $item ) {  
$chckd\_list+=$temp\_list  
return $chckd\_list }  
else {  
$chckd\_list+=$check\_item  
return (remove-item-list -item $item -chckd\_list $chckd\_list -list $temp\_list )}  
}  
`
```

Removing based on index number.

```
`
function remove-index-list ([int]$count=0,[int]$index,[array]$chckd_list=@(),[array]$list)
{if (($list.length+$count-1) -lt $index ) { throw "the index is out of range" }
$check_item,$temp_list=$list
if ($count -eq $index) {
$chckd_list+=$temp_list
return $chckd_list}
else {
$chckd_list+=$check_item
return (remove-index-list -count ($count + 1) -index $index -chckd_list $chckd_list -list $temp_list )}

}  
`
```
