If you must make sure that a given string has a uniform width, then you can use .NET methods to pad the string appropriately:

PS C:\> $mytext = 'Test' PS C:\> $paddedText = $mytext.PadLeft(15) PS C:\> "Here is the text: '$paddedText'" Here is the text: '           Test' PS C:\> PS C:\> $paddedText = $mytext.PadRight(15) PS C:\> "Here is the text: '$paddedText'" Here is the text: 'Test           '

You can even add a padding character yourself (if you do not want to pad with spaces):

PS C:\> 'Hello'.PadLeft(20, '.') ...............Hello PS C:\> 'Hello'.PadRight(20, '_') Hello_______________

PadLeft()
PadRight()
这两个方法，是string类的方法。string类，就是字符串类，是最基本的类。
