Binaryworld - Right-align formatted strings ... [ VB.net -> String ]

The String.Format function supports many formatting options, but none allows you to display right-aligned columns of numbers, as in:

1.00
12.00
123.00
1,234.00

However, you can easily create a helper function that works like String.Format, takes an additional length argument, and aligns the result to that length:

Click here to copy the following block

Function RightFormat(ByVal formatString As String, ByVal length As Integer, _
ByVal value As Object) As String
Return String.Format("{0:" & formatString & "}", value).PadLeft(length)
End Function

Here's an example of how you can use the above function:

Click here to copy the following block

Dim n As Integer
For Each n In New Integer() {10, 100, 1000, 1000}
Console.WriteLine(RightFormat("##,##0.00", 10, n))
