Multi Spaces should convert in to single space

public static string NormalizeWhiteSpace(string S)

{

string s = S.Trim();

bool iswhite = false;

int sLength = s.Length;

foreach (char c in s.ToCharArray())

{

{

{

continue;

}

else

}

}

else

{

sb.Append(c.ToString());

iswhite = false;

}

}

return sb.ToString();
