value = Regex.Replace(value, “\\s+”, ” “);

Code above will leave only single spaces in between words and remove any whitespace character.

I have found Regex to be quite slow. A less pretty but faster solution could look like this:

while (v.IndexOf(” “) > 0)
v = formatted_v.Replace(” “, ” “);

leaving only single spaces.

StringBuilder would be better than String.

Or you could put together a clever little recursive using IndexOf and Remove.

string sourceString = “This is my India.”;
string stringToReplace = “i”;
string outputString = sourceString.Replace(stringToReplace.ToLower(), null).Replace(stringToReplace.ToUpper(), null);
Console.WriteLine(outputString);

@HFM Solutions: Use the string.Replace() method, but be sure to pass “i” as a string and not the character ‘i’:

string s = “This is my India.”;
s = s.Replace( “i”, null );
Console.WriteLine( s );

Output: Ths s my Inda.

@cayber: It’s possible the characters after “abc.wav” are not normal whitespace (maybe they are control characters) in which case the Trim method won’t work, and you would need to manually remove non-alphabetical and non-numeric characters.
