Split string only after the first word which is separated by multiple spaces

Question

I would like to split a string only after the first word which has more than two spaces b/w them. For example:

string myString = "AAAA AAA DDD    BBBB BBB BBB        CCCCCCCC";

I want to split it into these:

"AAAA AAA DDD"   
"BBBB BBB BBB        CCCCCCCC"

Please help.

What have you tried till now? BTW: Your criteria to split string into mutiple "words" are not clear. — Maciej Los, Jun 28 '17 at 15:04
I tried this var array = myString.Split(new string[] {" "}, StringSplitOptions.RemoveEmptyEntries); — User2309, Jun 28 '17 at 15:06
If this the case: "AAA BB CCC DDDD", I want this string into two separate words like "AAA BB" and "CCC DDDD" — User2309, Jun 28 '17 at 15:07
`"CCCCCCCC"` is more than two spaces away from `"BBBB BBB BBB"` - shouldn't that become it's own entry after splitting? — trashr0x, Jun 28 '17 at 15:13
Ugly, but: `myString.Replace(" ", "|").Split(new char {'|'}, StringSplitOptions.RemoveEmptyEntries);` — ebyrob, Jun 28 '17 at 15:21

Substring is the simplest way:

string myString = "AAAA AAA DDD    BBBB BBB BBB        CCCCCCCC";
int splitIndex = myString.IndexOf("  ");
if (splitIndex > 0)
{
    Console.WriteLine(myString.Substring(0, splitIndex).Trim());
    Console.WriteLine(myString.Substring(splitIndex).Trim());
}
else
    throw new FormatException();

Another option is to use Regex:

string myString = "AAAA AAA DDD    BBBB BBB BBB        CCCCCCCC";   
Regex searchTerm = new Regex("[ ]{2,}", RegexOptions.None);


var splitedData = searchTerm.Replace(myString, "|").Split(new string[]{"|"},StringSplitOptions.RemoveEmptyEntries);

foreach(var d in splitedData)
{
    Console.WriteLine("{0}", d);
}

Result:

AAAA AAA DDD
BBBB BBB BBB
CCCCCCCC

My solution is based on this: How do I replace multiple spaces with a single space in C#?
