Features

  • Colored log events in a WinForms RichTextBox control
  • Multiple theme presets with customization options
  • High-performance asynchronous processing
  • Line limit to control memory usage
  • Support for pretty-printing of JSON objects
  • WCAG compliant color schemes based on the Serilog WPF RichTextBox sink.

Getting Started

Install the package from NuGet:

Install-Package Serilog.Sinks.RichTextBox.WinForms.Colored

Declare your RichTextBox control:

private System.Windows.Forms.RichTextBox richTextBox1;

private void InitializeComponent()
{
    this.richTextBox1.BackColor = System.Drawing.SystemColors.Window;
    this.richTextBox1.Dock = System.Windows.Forms.DockStyle.Fill;
    this.richTextBox1.Font = new System.Drawing.Font("Cascadia Mono", 10.8F, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point);
    this.richTextBox1.Location = new System.Drawing.Point(0, 0);
    this.richTextBox1.Name = "richTextBox1";
}

Configure the logger to use the sink using the RichTextBox extension method:

Log.Logger = new LoggerConfiguration()
    .WriteTo.RichTextBox(richTextBox1, theme: ThemePresets.Literate)
    .CreateLogger();

Log.Information("Hello, world!");

See the Extension Method for more configuration options.

Configuration Options

Option Description Default Value
theme The color theme applied when rendering individual message tokens. ThemePresets.Literate
autoScroll When true (default) the target control scrolls automatically to the most recent log line. true
maxLogLines Maximum number of log events retained in the in-memory circular buffer and rendered in the control. 256
outputTemplate Serilog output template that controls textual formatting of each log event. [{Timestamp:HH:mm:ss} {Level:u3}] {Message:lj}{NewLine}{Exception}
formatProvider Optional culture-specific or custom formatting provider used when rendering scalar values; null for the invariant culture. CultureInfo.InvariantCulture
prettyPrintJson When true, formats JSON values with indentation and line breaks for better readability. false
spacesPerIndent Number of spaces per indentation level when pretty printing JSON. 2

Themes

Available built-in themes:

Theme Description
ThemePresets.Literate Styled to replicate the default theme of Serilog.Sinks.Console (default)
ThemePresets.Grayscale A theme using only shades of gray, white, and black
ThemePresets.Colored A theme based on the original Serilog.Sinks.ColoredConsole sink
ThemePresets.Luminous A light theme with high contrast for accessibility

The themes based on the original sinks are slightly adjusted to be WCAG compliant, ensuring that the contrast ratio between text and background colors is at least 4.5:1.

You can create your own custom themes by creating a new instance of the Theme class and passing it to the RichTextBox extension method. Look at the existing themes for examples.
