whole word substring search w/o using regular expressions

[seannakasone]

Is there a way to search a string for a whole word w/o using a regular
expression?

i.e.
mystring.IndexOf(mypattern, *WholeWord);

The reason i rather not use a regular expression is because sometimes i
want to search for whole words w/o the regular expression special
characters being interpreted.

Why not simply escape the relevant characters in the word and then
build it into a regular expression? You could then wrap it all in a
method call:

int wordIndex = WordIndex(myString, wordString);

Do you know what word separators will be involved? In other words, will
there always be spaces between words?

You can use Regex.Escape to escape all the special characters, then use
the normal word boundary character classes etc. That sounds like the
best bet here, unless the word delimiter will always be the exact same
thing.

In that case, you could just use foo.IndexOf (" "+word+" ")

You could use foo.StartsWith (word+" "),
foo.EndsWith(" "+word) and
foo.Equals(word)

to check for edge cases.
