How to create ConfigLexem for Comment statement programmatically in WinForms SyntaxEditor (EditControl)?

Configuration for custom comments
The configuration settings for custom comments can be created as outlined in the steps below.
1. Create an ISnippetFormat for the custom comment.
2. Create a ConfigLexem associated with the comment.
3. Add the ConfigLexem to the EditControl’s Language.Lexems collection.
4. Add the ConfigLexems which are used as sub-lexems to the parent ConfigLexem.SubLexems collection.
5. Create two separate Split entries for the lexems used for opening and closing the comments, i.e., ‘/*’ and ‘*/’.
C#
// Multi-character splits should be added to make tokenizer read them as a single word. currentConfigLanguage.Splits.Add( "/*" ); currentConfigLanguage.Splits.Add( "*/" ); ConfigLexem commentLexem = new ConfigLexem(); commentLexem.BeginBlock = "/*"; commentLexem.EndBlock = "*/"; commentLexem.Type = FormatType.Custom; commentLexem.FormatName = "Comment"; commentLexem.OnlyLocalSublexems = true; commentLexem.IsComplex = true; commentLexem.IsCollapsable = true; commentLexem.CollapseName = "/*...*/"; ConfigLexem commentSubLexem = new ConfigLexem(); commentSubLexem.BeginBlock ="\\n";// or @"\n" commentSubLexem.IsBeginRegex = true; commentSubLexem.Type = FormatType.Custom; commentSubLexem.FormatName = "Comment"; commentSubLexem.ParentConfig = commentLexem; commentLexem.SubLexems.Add(commentSubLexem); // Configuration lexems can not be placed into two or more containers currentConfigLanguage.Lexems.Add(commentLexem); currentConfigLanguage.ResetCaches(); // Configuration should be applied just once, and just after it is completely created. this.editControl1.ApplyConfiguration(currentConfigLanguage);
