How to use lexical macros in code to specify regular expressions in WinForms SyntaxEditor (EditControl)?

this.editControl1.ApplyConfiguration(KnownLanguages.HTML);
IMacro macro = this.editControl1.LexicalMacrosManager.Add("testMacro", ".+");
// Create a format and set its attributes 
ISnippetFormat formatMethod = this.editControl1.Language.Add("CodeBehind"); 
formatMethod.FontColor = Color.IndianRed; 
formatMethod.Font = new Font("Garamond",12); 
formatMethod.BackColor = Color.Yellow;
// Create a lexem that belongs to this format 
ConfigLexem configLex = new ConfigLexem("<%@", "%>", FormatType.Custom, false); 
configLex.IsBeginRegex = false; 
configLex.IsEndRegex = false;
// NameInConfig returns name of the macro rounded with braces, like "{testmacro}"
configLex.ContinueBlock = macro.NameInConfig; 
configLex.IsContinueRegex = true; 
configLex.FormatName = "CodeBehind"; 
this.editControl1.Language.Splits.Add("<%@");
this.editControl1.Language.Splits.Add("%>");
// Add it to the current language's lexems collection 
this.editControl1.Language.Lexems.Add(configLex); 
this.editControl1.Language.ResetCaches();
