Basic System.Diagnostics

HosamKamel — Sat, 05 Apr 2008 02:42:38 GMT

The .NET framework has shipped with the System.Diagnostics namespace since version 1.0. My efforts to build a method context information gathering framework on the services of System.Diagnostics has brought me a deeper understanding of its classes and configuration settings. I will talk about my method context information gathering framework in a later post, but first I thought I would get us all on the same page on System.Diagnostics.

System.Diagnostics implements several classes that play a key role in outputting trace text from your application. Better understanding these classes will bring you insights in to how to extend the existing diagnostic framework in .NET or how to set up the configuration file to make full use of the out-of-the-box functionality.

Restore Machine.Config file

HosamKamel — Wed, 30 Jan 2008 07:31:54 GMT

If you made any changes to machine.config file and wish to restore it to its default , the .NET 2.0 framework provide a backup for this file incase you wish to reset it.

You will find two files in the framework installation path (\%SystemRoot%\Microsoft .NET\Framework\%VersionNumber%\CONFIG\) :

- machine.config.comments : contains a descriptive comments for each key in the machine.config along with it's default or recommended value.

- machine.config.default: contains the original machine.config values

To restore the original file just copy the content or copy the file and rename it.

(BTW : this post belongs to do more with less using .NET series which I promised to continue)

TryParse() method in .NET 2.0

HosamKamel — Tue, 02 Oct 2007 20:25:29 GMT

TryParse method is exposed by several classes in the System namespace

System.Boolean.TryParse(System.String,System.Boolean)
System.Byte.TryParse
System.DateTime.TryParse
System.Char.TryParse(System.String,System.Char)
System.Decimal.TryParse
System.Double.TryParse
System.Int16.TryParse
System.Int32.TryParse
System.Int64.TryParse
System.SByte.TryParse
System.Single.TryParse
System.UInt16.TryParse
System.UInt32.TryParse
System.UInt64.TryParse

TryParse is new in .NET 2.0 which provide the functionality to check if the type applicable to be parsed or not without raising an exception like Parse method do, and this of course solved and replaced the common snippet written by each developer to ensure proper handling for type parsing.

.NET 1.1

 1: try

 2: {

 3:  int.Parse(sampleString);

 4:  }

 5: catch(System.FormatException formatException)

 6: {

 7:  Console.WriteLine("invalid string formate");

 8: }

In .NET 2.0 you can use the following

 1:  if (int.TryParse(sampleString, out number))

 2:  Console.WriteLine(number);

What about Performance !!!

For Performance comparison between both methods you can read IanWho's post about this here Performance Profiling Parse vs. TryParse vs. ConvertTo
