TraceUtilities.Configure() does not close log file after writing – how to close?

[MS]

I'm calling

TraceUtilities.Configure(TraceUtilities.DETAILED_REQUEST_LOGS_SOURCE, logFile, SourceLevels.All);

for logging my Google Ads API calls.

However, when calling

TraceUtilities.Configure(TraceUtilities.DETAILED_REQUEST_LOGS_SOURCE, logFile, SourceLevels.All);

a second time on the same file, a "System.IO.IOException" is thown with error message: "The process cannot access the file 'C:\\Temp\\Detailed.log' because it is being used by another process."

How do I correctly close a log file once it has been opened?

Hi,

Thank you for reaching out to the Google Ads API support team.

To investigate the error further, kindly provide the complete API logs (request and response logs with request-id and request header) generated at your end when using the Google Ads API. These logs will help us to analyze the error details, and we can assist you accordingly.

Kindly note that you have to enable logging if you are using a client library. You can refer to the guides for Java, .Net, PHP, Python, Ruby, or Perl to enable logging at your end. For REST interface requests, you can enable logging via the curl command by using the -i flag.

You can send the details via the Reply privately to the author option or direct private reply to this email.

Thanks,
 

Google Ads API Team
