namespace LoggerWrapper.Logger;
public class TextBoxLogger : ILogger
{
public TextBox? TextBox { get; set; }
public void Log(LogEntry entry)
{
TextBox?.AppendText(
$@"[{entry.Severity}] {DateTime.Now} {entry.Message} {entry.Exception}");
TextBox?.AppendText(Environment.NewLine);
}
}
Notice:
public TextBox? TextBox { get; set; }
Later, I will connect this property to the actual TextBox in Form1. Here’s what my Program.cs looks like:
using LoggerWrapper.Logger;
namespace LoggerWrapper
{
internal static class Program
{
[STAThread]
static void Main()
{
ApplicationConfiguration.Initialize();
var textBoxLogger = new TextBoxLogger();
var someDiClassHandler = new SomeDiClassHandler(textBoxLogger);
Form1 form1 = new Form1(someDiClassHandler);
textBoxLogger.TextBox = form1.TbLogger;
Application.Run(form1);
}
}
}
Notice:
textBoxLogger.TextBox = form1.TbLogger;In Form1, I introduced a property named TbLogger:
namespace LoggerWrapper;
public partial class Form1 : Form
{
public TextBox? TbLogger { get; }
private readonly SomeDiClassHandler _someDiClassHandler;
public Form1(SomeDiClassHandler someDiClassHandler)
{
InitializeComponent();
TbLogger = tbLogger;
_someDiClassHandler = someDiClassHandler;
}
private void btnStart_Click(object sender, EventArgs e)
{
SomeDiClassCommand someDiClassCommand = new SomeDiClassCommand();
_someDiClassHandler.Execute(someDiClassCommand);
}
}
After creating Form1 I will assign TextBox to my TextBoxLogger, and in Form1 constructor I will assign TbLogger to real TextBox, in my case tbLogger:
TbLogger = tbLogger;

Since validation result is XML, we can parse failed validations like:
IEnumerable<FailedAssert> failedAsserts = doc.Descendants(svrl + "failed-assert")
.Select(fa => new FailedAssert
{
Flag = fa.Attribute("flag")?.Value,
Id = fa.Attribute("id")?.Value,
Test = fa.Attribute("test")?.Value,
Location = fa.Attribute("location")?.Value,
Text = fa.Element(svrl + "text")?.Value
});
SVRL is an abbreviation for 'Schematron Validation Report Language.'
FailedAssert class looks like:
public class FailedAssert
{
public string Flag { get; set; }
public string Id { get; set; }
public string Test { get; set; }
public string Location { get; set; }
public string ExceptionMessage { get; set; }
public string Text { get; set; }
}
Example download from here. For this example I used file 01.03a-INVOICE_uncefact.xml which I downloaded from here where I manipulated with DateTimeField. Instead of a date I wrote "test", in order to trigger a failed assertion. I also downloaded XSL file EN16931-CII-validation.xsl from "Koordinierungsstelle für IT-Standards" (KoSIT) GitHub repository.
