String.Trim method - Removes all occurrences of white space characters from the beginning and end of this instance.
Trim(var) method - returns a string with no leading or trailing spaces
Yes, there is a difference between these. The String.Trim will remove any non-visible characters such as line feeds and carriage returns.
How I came across this was as a result of an odd exception I am getting from an application. Randomly the NameValueCollection after a postback will have an appended or prepended line feed.
When the codebehind tries to ctype(hidCurrent, Boolean) it recieves True or False with additional hidden line feeds. This is within an ASP.NET 2.x web application. I have yet to find the source of this problem but I am hoping the String.Trim() will help me out here. If you have any ideas please let me know what may be going on here.
