If i use the replace function in c#
string a = "this";
a.replace("is", "something" );
my output would be like thsomething
how can i replace when only the whole word matches.
string a = "is";
a.replace("is", "something" );
output: something
Thanks

Use:
string a = "is";
a = Regex.Replace(a , @"\bis\b", "something" );

"\b" matches for a word boundary. See: http://tinyurl.com/5uvwz
what if the string is just one work "is" not " is "??
Not sure what you mean... "\b is \b" (including the spaces) would match:
"this is fine", but not "a, is b", because ", " is no word boundary.

what is the string only has one word
a = "is";
there's no /b in that string

Sure there is. End of string is a word boundary. Why would you think
it isn't? Remember in a regular expression, there is not necessarily a
one-to-one correlation between letter in the pattern and letters in the
matched string.

As explaind in the link I've sent you, "\b" is a zero-width assertion: It
doesn't match a character, it matches a position in a string where left of
the position is a word character (a-z,A-Z,0-9,_), while right of it isn't
(or vice versa). In the string "is", at position 0 there'a word character
('i') to the right, but no word character to the left, thus \b matches. Same
applies for the end of the string.

Hi all,
I searching a string to see if "Desc" resides in it, if so then replace it
with "Description". For some reason if it finds "Desc" in the word
"Description" it replaces the "Desc" part of it with "Description thus having
the final outcome of "Descriptionription". Is there a way to have the
replace() method only replace if the entire string is "Desc" only and not
"Desc* " ? Hope this makes sense. Thanks in advance.

Suppose you need to do find and replace of a string pattern, for all
files in a directory. However, you do not want to replace all of them.
You need to look at it in a case-by-case basis. What can you do?

Hello:
I am hoping someone knows if there is an easier way to do this or someone
already implemented something that does this, rather than reinventing the
wheel:
I have been using the string.replace(from_string, to_string, len(string))
to replace names in a file with their IP address.
For example, I have definitions file, that looks something like:
10.1.3.4 LANDING_GEAR
20.11.222.4 ALTIMETER_100
