var array = theString.Split(' ', 2);

string[] words = phrase.Split(' ');

foreach (var word in words)
{
    System.Console.WriteLine($"<{word}>");
}

string[] separatingStrings = { "<<", "..." };

string text = "one<<two......three<four";
System.Console.WriteLine($"Original text: '{text}'");

string[] words = text.Split(separatingStrings, System.StringSplitOptions.RemoveEmptyEntries);
System.Console.WriteLine($"{words.Length} substrings in text:");

foreach (var word in words)
