Pop3Client Activity Logging

Activity logging is used for debugging, as well as for collecting and analyzing working information about the POP3 client.

Enable Activity Logging using appsettings.json File

NOTE: This option is preferred for .NET Core applications.

Logging in Pop3Client can be enabled with the following steps and code samples:

1. Add an appsettings.json configuration file to a C# project, if it has not been added before.

2. Make sure that the project file contains the following lines in the ItemGroup section.

      <Content Include="appsettings.json">
          <CopyToOutputDirectory>Always</CopyToOutputDirectory>
      </Content>
   

3. Then, add the following content to the appsettings.json file.

      {
        "Pop3DiagnosticLog": "Pop3.log",
        "Pop3DiagnosticLog_UseDate": true
      }
   

The two properties mentioned above are:

• Pop3DiagnosticLog - specifies the relative or absolute path to the log file.

• Pop3DiagnosticLog_UseDate - specifies whether to add a string representation of the current date to the log file name.

Enable Activity Logging in Programm Code

You can also enable logging immediately in the code.

NOTE: even if you have already enabled logging by using configuration files, this option will be applied.

Logging in Pop3Client can be enabled with the following steps and code samples:

1. Create an Pop3Client.
2. Set the path to the log file using the LogFileName property.
3. Set the UseDateInLogFileName property if it is necessary.

   using (var client = new Pop3Client("your pop3 server", 995, "your username", "your password"))
{
    // Set security mode
    client.SecurityOptions = SecurityOptions.Auto;

    // Set the path to the log file using the LogFileName property.
    client.LogFileName = @"C:\Aspose.Email.Pop3.log";

    // Set the UseDateInLogFileName property if it is necessary.
    client.UseDateInLogFileName = false;
}

Enable Activity Logging using App.config File

Pop3Client activity can be logged by modifying the configSections in the config file. Following are the steps to perform diagnostics logging:

1. Add a sectionGroup called “applicationSettings”.
2. Add a section called “Aspose.Email.Properties.Settings”.
3. Include the setting ImapDiagonosticLog where the file name is defined in the applicationSettings/Aspose.Email.Properties.Settings.

Here is a sample form application which uses Pop3Client to process mail. This whole activity is logged by modifying the App.config file.

• Create a form based application with a single button on it. Add the following sample code for the button click:

• Add a reference to Aspose.Email.
• Now add the App.Config file and modify it so that the file contents are as follows:

For C# .NET use the following option

For VB .NET use the following option

• Run the code and then observe the Log folder. The following file will be generated.
