C# program that uses Debug.WriteLine

using System.Diagnostics;

static class Program
{
    static void Main()
    {
        Debug.Write("A");
        Debug.Write("B");
        Debug.Write("C");
        Debug.Write(" ");
        Debug.WriteLine("Message is written");
    }
}

It will write “ABC Message is written” to the Output window

C# program that uses DelimitedListTraceListener

using System.Diagnostics; 
class Program 
{ 
  static void Main() 
  { // Create trace listener. 
    TraceListener listener = new 
    DelimitedListTraceListener(@"C:\debugfile.txt"); // Add listener. 
    Debug.Listeners.Add(listener); // Write and flush. 
    Debug.WriteLine("Welcome"); 
    Debug.Flush(); 
  } 
}

Result: debugfile.txt

Welcome

C# program that uses Indent and Unindent

using System.Diagnostics;

class Program
{
    static void Main()
    {
        // 1.
        Debug.WriteLine("One");

        // Indent and then unindent after writing.
        Debug.Indent();
        Debug.WriteLine("Two");
        Debug.WriteLine("Three");
        Debug.Unindent();

        // End.
        Debug.WriteLine("Four");

        // Sleep.
        System.Threading.Thread.Sleep(10000);

    }
}

One Two Three Four

C# program that uses IndentSize

using System.Diagnostics;

class Program
{
    static void Main()
    {
        // Write IndentSize.
        Debug.WriteLine(Debug.IndentSize);

        // Change IndentSize.
        Debug.IndentSize = 2;
        Debug.IndentLevel = 1;
        Debug.WriteLine("Perls");

        // Sleep.
        System.Threading.Thread.Sleep(10000);
    }
}

C# program that demonstrates WriteLineIf

using System;
using System.Diagnostics;

class Program
{
    static void Main()
    {
        Debug.WriteLineIf(IsThursday(), "Thursday");
        Debug.WriteLineIf(_flag, "Flag");
        Debug.WriteLineIf(int.Parse("1") == 1, "One");

        Debug.WriteIf(true, "True");
        Debug.WriteIf(true, "True");
        Debug.WriteIf(false, "False");

        Debug.WriteLine("Done");
        Console.ReadLine();
    }

    static bool IsThursday()
    {
        return DateTime.Today.DayOfWeek == DayOfWeek.Thursday;
    }

    static bool _flag = true;
}

C# program that uses Assert method

using System;
using System.Diagnostics;

static class Program
{
    static void Main()
    {
        int value = -1;
        // A.
        // If value is ever -1, then a dialog will be shown.
        Debug.Assert(value != -1, "Value must never be -1.");

        // B.
        // If you want to only write a line, use WriteLineIf.
        Debug.WriteLineIf(value == -1, "Value is -1.");
    }
}

A. The dialog is displayed.
B. Message is written to the Output: Value is -1.
