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.
hidCurrent: True hidOrderID: -1
When the code behind 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.
