Delete spaces after end of string containing two words VB.NET 2005
I would like to take a string and if it has two words in it, I would like to strip any spaces that occur at the end of the string (something like a "trim right"). However, if it is only one word, then I would like to leave a single space after the word, if the user entered it, and get rid of anything else which occurs after. For example:
"Hello, world " gets converted to "Hello, world"
"Hello " gets converted to "Hello "
How do I do this in VB.NET 2005?
Thanks.
"Hello, world " gets converted to "Hello, world"
"Hello " gets converted to "Hello "

You can check the no of spaces in a string using string function(IndexOf(' ')) and space count is grater than 2 use Trim function, otherwise add a space at the end.

Is there any way to say if I can find in the string "[a-Z]<space>[a-Z]" then do a TrimEnd, else leave it alone?
Well you could check the string with a regexp then use an if() to check for matching the conditionally run the TrimEnd()

Sabeesh,
I will, after converting to VB which should not be a problem. Will it work under these circunstances:
"hello world" is unchanged
"hello world " (one space after) becomes "hello world" (no spaces after)
"hello " (one space after) is unchanged because it is only one word
"hello " (several spaces after) becomes "hello " (one space after)
Thanks.

string str = "hello ";
Regex r = new Regex(@"\s{1,}");
Match m = r.Match(str.TrimEnd());
if(m.Success )
{
str = str.TrimEnd();
}
You can try this also. so this will remove space from the end and later you can add the space at the end if it is required.

inside if condition I am checking if the entered string contains only one word then the final string will have one space added at the end
