Hey buddies, why did you close the question? These are not the same Question. — Jahan Zinedine, Dec 12 '10 at 15:41
Here are two more solutions by LINQ. IEnumerable enumerable = preString.Select( c => Char.IsUpper(c) ? " " + c.ToString(): c.ToString()); MessageBox.Show(string.Concat(enumerable.ToArray())); IEnumerable selectMany = preString.SelectMany(o => Char.IsUpper(o) ? o.ToString() : " " + o.ToString()); MessageBox.Show(new string(selectMany.ToArray())); — Jahan Zinedine, Dec 12 '10 at 17:31

Try:

String preString = "HelloWorld";
StringBuilder sb = new StringBuilder();

foreach (char c in preString)
{
    if (Char.IsUpper(C))
        sb.Append(' ');
    sb.Append(C);
}

string result = sb.ToString();

might want to then do a Split to get it into an array? – devrooms Dec 12 '10 at 15:12
Yes, just split by white space... – Tee Wu Dec 12 '10 at 15:13
@nofortee Remove the first space you've added and change the iteration variable to lower case c – Jahan Zinedine Dec 12 '10 at 15:19
@Jani: thanks for the reminding. I think the above code just give the clues about how to do that. Of course there's a little modification need to be done to fixed one's need. Thanks indeed. – Tee Wu Dec 12 '10 at 15:23
