Insert newline character after specific number of words

Question

I want to insert a new line character(\n) after 9 words in my string such that the string after the 9th word is in next line.

string newline="How to insert newline character after ninth word of(here) the string such that the remaining string is in next line"

Stucked here:

foreach (char x in newline)
{
    if (space < 8)
    {                    
        if (x == ' ')
        {
            space++;
        }
    }

}

Don't know why I got stucked. Its quite simple I know.
If possible, show any other simple method.

Thank you!

Note: Found an answer for myself. Given by me below.

Answer 1

For what it's worth, here's a LINQ one-liner:

string newline = "How to insert newline character after ninth word of(here) the string such that the remaining string is in next line";
string lines = string.Join(Environment.NewLine, newline.Split()
    .Select((word, index) => new { word, index})
    .GroupBy(x => x.index / 9)
    .Select(grp => string.Join(" ", grp.Select(x=> x.word))));

Result:

How to insert newline character after ninth word of(here)
the string such that the remaining string is in
next line
