string.Trim() Behavior

According to the intellisense help, string.Trim() "Removes all occurances or
white space characters from the beginning and end of this instance."

However, the follow code does not appear to modify s.

s.Trim('\r');

While the follow code DOES modify s.

s = s.Trim(\r');

I understand that the help text quoted above is for the version of this
method that takes no arguments. But I would assume that variations of Trim
work the same fundamental way.

If this is modifying this instance, why do I only get the effect if I assign
the result?

Thanks.

No worries. This group is about .NETish things as well.

You problem is that System::Strings are immutable.
the Trim method returns a new string without the whitespace.

You can then assign that string to s again, after which the original s
string can be garbage collected.
None of the methods you can call on a System::String can change the string
itself.

Hi I have a problem with JSP on websphere 5. When I try save information with swedish or danish ÅÄÖ characters, the string is cut where the first of these characters occurs. The JDK used is 1.3.1 I've tried: String CUNM = request.getParameter("CUNM").trim(); CUNM = URLDecoder.decode(CUNM,"UTF-8");

I have an app that makes decisions based on string content. I need to make sure that a string does not contain only spaces or newlines. I am using the syntax 'Trim(String)" and it works fine. I thought I'd change it to the VB ..NET method "String.Trim" but that throws an object exception. Which brings the question: is it compliant to use Trim(String), or is it more within etiquette to use If Not String Is Nothing Then String.Trim?

Hi, I am using VB 2005. My application has many data bound controls. The connection is stored in the app.config file. I want the application to start with a default connection string and while during the runtime, the user can click on a button and change the connection string without exiting the application. I would really appreciate any sort of help.
