+上传文件，使用 `OpenAiCompatibleUploadFileAsync()` 方法传入文件：

-var file1 = await client.UploadFileAsync(File.OpenRead("1024-1.txt"), "file1.txt");
+var file1 = await client.OpenAiCompatibleUploadFileAsync(File.OpenRead("1024-1.txt"), "file1.txt");
 ```
 
-然后将文件作为 `system` 消息传入消息数组中，注意第一条 `system` 消息不能省略，否则模型可能会将文件里的内容当作 System prompt 。
+如果文件比较大，服务端可能需要几秒的时间进行解析。根据返回的 `file.Status` 属性是否为 `processed` 可以判断是否解析完成。未解析完成的文件无法被模型使用，需要等待解析完成。以下是一个示例方法，自动等待文档解析完毕或超时抛出异常：

+    IDashScopeClient client,
+    DashScopeFileId id,
+    int timeoutInSeconds = 5)
