Abstract
Sometimes you need to limit the length of a string by truncating it, but you don't want to leave a fraction of a word behind. Using this VBScript function, you can limit the length of a string while retaining only complete words.

Introduction
For the front page of the aspalliance.com site, we were trying to show a substring of article descriptions truncated after so many characters and then followed by "...more!" as a link for people to click to read the full article. Since I only wrote the thing using the VBScript "Left" function, it was indiscriminately cutting off the description in mid-word. This didn't really bother me too much, but it wasn't ideal. Well, it bothered one of our readers enough for them to do something about it, and so they sent in a function to truncate the description, but to ensure that no words are cut off.

Title: ASP.NET Version

I've created a .NET Version of the function (Both VB.NET as C#)

VB.NET:

Function truncLine(ByVal inputString As String, ByVal maxlength As Integer) As String
If inputString.Length > maxlength Then
inputString = inputString.Substring(0, maxlength)
inputString = inputString.Substring(0, inputString.LastIndexOf(" "))
End If
truncLine = inputString
End Function

C#

public string truncLine(string inputString, int maxlength)
{
if (inputString.Length > maxlength) {
inputString = inputString.Substring(0, maxlength);
inputString = inputString.Substring(0, inputString.LastIndexOf(" "));
}
return inputString;
}
