-If you're using [Visual Studio 2022 version 17.8 or later](/visualstudio/releases/2022/release-notes), you can try the AI-driven [GitHub Copilot in Visual Studio](/visualstudio/ide/visual-studio-github-copilot-install-and-states) to generate code to split an input string into substrings based on one or more delimiters. Submit your question as a prompt in the Copilot chat window, as in the following example. You can also submit prompts using [inline chat](/visualstudio/ide/visual-studio-github-copilot-chat#ask-questions-in-the-inline-chat-view) in the editor window itself.

@@ -20,7 +20,10 @@ You convert a `string` to a number by calling the `Parse` or `TryParse` method f
 It's slightly more efficient and straightforward to call a `TryParse` method (for example, [`int.TryParse("11", out number)`](xref:System.Int32.TryParse%2A)) or `Parse` method (for example, [`var number = int.Parse("11")`](xref:System.Int32.Parse%2A)). Using a <xref:System.Convert> method is more useful for general objects that implement <xref:System.IConvertible>.
 
 You use `Parse` or `TryParse` methods on the numeric type you expect the string contains, such as the <xref:System.Int32?displayProperty=nameWithType> type. The <xref:System.Convert.ToInt32%2A?displayProperty=nameWithType> method uses <xref:System.Int32.Parse%2A> internally. The `Parse` method returns the converted number; the `TryParse` method returns a boolean value that indicates whether the conversion succeeded, and returns the converted number in an `out` parameter. If the string isn't in a valid format, `Parse` throws an exception, but `TryParse` returns `false`. When calling a `Parse` method, you should always use exception handling to catch a <xref:System.FormatException> when the parse operation fails.

 ## Call Parse or TryParse methods
 
 The `Parse` and `TryParse` methods ignore white space at the beginning and at the end of the string, but all other characters must be characters that form the appropriate numeric type (`int`, `long`, `ulong`, `float`, `decimal`, and so on). Any white space within the string that forms the number causes an error. For example, you can use `decimal.TryParse` to parse "10", "10.3", or "  10  ", but you can't use this method to parse 10 from "10X", "1 0" (note the embedded space), "10 .3" (note the embedded space), "10e1" (`float.TryParse` works here), and so on. A string whose value is `null` or <xref:System.String.Empty?displayProperty=nameWithType> fails to parse successfully. You can check for a null or empty string before attempting to parse it by calling the <xref:System.String.IsNullOrEmpty%2A?displayProperty=nameWithType> method.
