C# Debug-Info

Hi,

a few days ago I found a quite cool feature:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33

using System; using System.Collections.Generic; using System.Diagnostics; using System.Linq; using System.Text; using System.Threading.Tasks; namespace TestProject { class Program { [DebuggerDisplay("Person: '{Name}'")] public class Person { public string Name { get; set; } public int Age { get; set; } } static void Main(string[] args) { var persons = new List<Person>(new Person[] { new Person() { Name = "Johnny Galecki", Age = 40}, new Person() { Name = "Kaley Cuoco-Sweeting", Age = 30}, }); Debugger.Break(); if (Debugger.IsLogging()) { persons.ForEach(x => Debugger.Log(0, "output", x.Name + Environment.NewLine)); } } } }

In line 12 DebuggerDisplay tells the Debugger to show the information "person" and then the person's name. E.g.: if you are running this example application the debugger will break (like setting a break-point) on line 25. When you check the variable using a "watch"-window or "local" you will see that the output is now something helpful instead of the full qualified class name.

Other important features related to Debug-Info:

• DebuggerStepThrough-Attribute
• DebuggerBrowsable-Attribute

kind regards,

Daniel
