The Unicode standard recognizes three subcategories of separators:

NoteNote:

The Unicode standard classifies the characters \u000A (LF), \u000C (FF), and \u000A (CR) as control characters (members of the UnicodeCategory.Control category), not as separator characters.

The following example demonstrates IsSeparator.


using System;

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      string str = "twain1 twain2";

      outputBlock.Text += Char.IsSeparator('a') + "\n";		// Output: "False"
      outputBlock.Text += Char.IsSeparator(str, 6) + "\n";	// Output: "True"
   }
}
