Question

Hi Is it possible to logging the error log into Local drive either ( c: or d: ) after hosting the application in iis . if anyone knows this suggest me with example code. Thanking you Karthik.K

It is generally not possible to directly save logs to the end user's local system using NLog or any other server-side logging framework. When hosting an application in IIS the application runs on the server and the log files are stored on the server's file system.

nlog.config: In your code files you can now use NLog to log messages. For example: using NLog; private static readonly Logger logger = LogManager.GetCurrentClassLogger(); // Log an error logger.Error(An error occurred. exception); // Log an informational message logger.Info(Informational message.);

In your ASP.NET Core project open the appsettings.json file and add a new section for logging configuration { Logging: { LogLevel: { Default: Information Microsoft: Warning Microsoft.Hosting.Lifetime: Information } FilePath: C:\Logs\error.log // Update the file path as per your requirement } // Other configuration settings... } we have specified the file path as C:\Logs\error.log for logging errors to the error.log file in the C:\Logs directory. You can change the file path and name as per your preference. Startup.cs file configure logging in the ConfigureServices method using Microsoft.Extensions.Logging; public class Startup { public void ConfigureServices(IServiceCollection services) { // Other configuration... services.AddLogging(builder => { builder.AddConfiguration(Configuration.GetSection(Logging)); builder.AddFile(options => { options.FileName = Configuration[Logging:FilePath]; }); }); // Other services... } // Other methods... } we are using the AddFile extension method from a third-party logging provider (such as Serilog.Extensions.Logging.File ). Make sure you have the necessary NuGet package installed for the file logging functionality. Now you can inject ILogger into your classes where you want to log errors and use it to log errors using Microsoft.Extensions.Logging; public class YourClass { private readonly ILogger _logger; public YourClass(ILogger logger) { _logger = logger; } public void SomeMethod() { try { // Your code that may throw an exception } catch (Exception ex) { _logger.LogError(ex An error occurred); } } } we inject ILogger into the constructor of YourClass and then use _logger.LogError to log an error with the exception details and a message. With the above configuration any errors logged using the logger will be written to the specified file path ( C:\Logs\error.log in our example) on the local drive. Make sure the application has appropriate write permissions to create and write to the specified file path.
