推荐答案
Flush()将当前在缓冲区中拥有的所有数据推送到App Insights服务.您可以在此处查看其源代码: https://github.com/Microsoft/ApplicationInsights-dotnet/blob/3115fe1cc866a15d09e9b5f1f7f596385406433d/src/Microsoft.ApplicationInsights/TelemetryClient.cs#L593 .
Flush() on TelemetryClient pushes all the data it currently has in a buffer to the App Insights service.You can see its source code here: https://github.com/Microsoft/ApplicationInsights-dotnet/blob/3115fe1cc866a15d09e9b5f1f7f596385406433d/src/Microsoft.ApplicationInsights/TelemetryClient.cs#L593.
通常，Application Insights将在后台批量发送数据，以便更有效地利用网络.如果启用了开发人员模式或手动调用Flush()，则会立即发送数据.
Normally, Application Insights will send your data in batches in the background so it uses the network more efficiently.If you have developer mode enabled or call Flush() manually, data is sent immediately.
通常，您不需要调用Flush().但是，如果您知道该过程将在那之后退出，那么您将需要调用Flush()来确保所有数据都已发送.
Typically you do not need to call Flush().But in a case where you know the process will exit after that point, you'll want to call Flush() to make sure all the data is sent.
