Context Variables 上下文变量
The context variables feature enables you to add files from your solution into your questions using the # symbol. By referencing a file in this way, you allow Copilot to access the content of the file and provide more targeted answers about it. For example, you can ask “How does the #file:’Main.cs’ file work?” or “What is the purpose of the #file:’Calculator.cs’ file?” and get relevant answers from Copilot Chat. You can add multiple files to one question.
