how to split a string with strings in c#

string phrase = "The quick brown    fox     jumps over the lazy dog.";
string[] words = phrase.Split(' ');

foreach (var word in words)
{
    System.Console.WriteLine($"<{word}>");
}
// To split a string use 'Split()', you can choose where to split
string text = "Hello World!"
string[] textSplit = text.Split(" ");
// Output:
// ["Hello", "World!"]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)
{
    System.Console.WriteLine(word);
}
