C3Logging 1.0.1

C3 Logging ILogger Extension

Small Library to enable ILogger to Log into database or text file

To install nuget package run

    Install-Package C3Logging -Version 1.0.0

In Program.cs add

using C3Logging.DatabaseLogging;
using C3Logging.FileLogging;

Extend host builder with

Host.CreateDefaultBuilder(args)
        .ConfigureLogging(x =>
        x.AddEventLog()
        .AddConsole()
        .AddDatabaseLogging("{YOUR-DB-CONNECTION-STRING}")
        .AddFileLogging(Directory.GetCurrentDirectory() + "/App_Data/")
        .AddFilter<DatabaseLoggerProvider>(logLevel => logLevel == LogLevel.Error)

If you want to log just specific type of errors you can set filtering for provider. Example for database provider to log only errors:

.AddFilter<DatabaseLoggerProvider>(logLevel => logLevel == LogLevel.Error)

Then use ILogger as usual and that's all.

If you want to log to database , create table in your database:

CREATE TABLE [dbo].[Logs](
	[Id] [int] IDENTITY(1,1) NOT NULL,
	[LogLevel] [nvarchar](max) NULL,
	[EventId] [nvarchar](max) NULL,
	[State] [nvarchar](max) NULL,
	[Exception] [nvarchar](max) NULL,
	[Message] [nvarchar](max) NULL,
	[ProccesTimeMiliSeconds] [nvarchar](max) NULL,
	[Host] [nvarchar](max) NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO

Example for blazor (on index.razor:

Inject logger:

@using Microsoft.Extensions.Logging
@inject ILogger<Index> Logger

Set Button to call function:

<button @onclick="@TestLogger" class="btn btn-primary">Test Logger</button>

Set in code:

    @code{
 void TestLogger()
    {
        try
        {
            Logger.LogError("testing Warning");
            Logger.LogInformation("testing Information");
            Logger.LogWarning("testing warning");
            Logger.LogCritical("testing critical");
            throw new System.ArgumentException("Testing Catch for library", "testing catch exception");

        }
        catch (Exception ex)
        {
            Logger.LogError(ex, "testing catch exception");
        }

    }
}

That's it.
