Use Insert() to insert new text into an existing string at a given position. Here is an example:
$text = "Server failed" 1..100 | ForEach-Object { $text.Insert(6, $_) }
It produces a list of servers with an increment. Of course, this particular problem could have solved differently with PowerShell because you can insert variables directly:
1..100 | ForEach-Object { "Server $_ failed" }
However, when you have text that you do not control, for example file names or CSV content, then Insert() is a great alternative.
