C# String.Split() method isn't behaving itself

ClairelyClaire · March 2017

I'm trying to test some code with String.Split(), and it's trying to force me to only use a single-character char array, and it won't accept the option System.StringSplitOptions parameter at all.

For instance, this sample code from MSDN fails because "<<" and "..." are multi-character char arrays:

void Main()
{
	char[] separatingChars = { "<<", "..." };

	string text = "one<<two......three<four";
	System.Console.WriteLine("Original text: '{0}'", text);

	string[] words = text.Split(separatingChars, System.StringSplitOptions.RemoveEmptyEntries);
	System.Console.WriteLine("{0} substrings in text:", words.Length);

	foreach (string s in words)
	{
		System.Console.WriteLine(s);
	}
}

It works just fine after you change char[] in the first line to string[].

It's still not working...

This works for me:

void Main()
{
   string[] separatingChars = { "<<", "..." };

   string text = "one<<two......three<four";
   System.Console.WriteLine ("Original text: '{0}'", text);

   string[] words = text.Split (separatingChars, System.StringSplitOptions.RemoveEmptyEntries);
   System.Console.WriteLine ("{0} substrings in text:", words.Length);

   foreach (string s in words)
   {
      System.Console.WriteLine (s);
   }
}

I got this to work by removing the new string[] portion on the first line.

Thanks!
