Extension Method

hello everybody,

Extension method are not well know but they are very powerfull.

This article is not a tutorial with extension method but an inventory around it.

When use it

Extension method must be use only for technical issues never for business requirement.

For example, you have a string and you want to split it into list of fix lenght substring (Why MS doesn’t includes in the box????)

public static class StringExtensions{    
    public static List<string> SplitIntoParts(this string input, int partLength)
    {        var result = new List<string>();
        int partIndex = 0;
        int length = input.Length;
        while (length > 0)
            var tempPartLength = length >= partLength ? partLength : length;
            var part = input.Substring(partIndex * partLength, tempPartLength);
            length -= partLength;}
        return result;

And the manner how we call it

string longString = "This is a very long string, which we want to
 split on smaller parts every max. 30 characters long."; // Length: 98
var partLength = 30;
var parts = longString.SplitIntoParts(partLength);

How implement it

As I said previously, extensions are designed for technicals cases. The extension’s code shall not exceed ten or twenty lines.

In Visual Studio,  I recommend to store extensions in one project dedicated. This project can be referenced in each artifact.

Moreover, you can manage your extensions near your client project, in fact String.SpliintParts method should be the same in your client A and your client B, so manage your extensions in your own project.

Where do I can find extensions method

I recommend a great site

It includes not only .NET extensions, but don’t use all extensions without reading the code. Make sure you understand what it does, and all methods may not bug free

News from C# 6

hi everybody,

Have you heard some news about Roslyn. Theis project is a compiler entierely recasting.  The project is now an open source project and it’s available on codeplex.

Let’s take a look around about the new functions

 Using Static

Now you can make an using on an object. That permit to import all static method without type the object name. Here is an example with String.Concat :

using System.String;
String a = « hello »;
String b = « world »;
Console.WriteLine(Concat(a, » « ,b, »! »);


Properties initialization

Now we can initialized properties to a default value at object initialization :

public class class1
public int cmpt {get;set;} = 42;

Note now you can create readonly property with the same syntax, but I prefer create a const member :

public class class1
public int cmpt {get;} = 42;


Improvement around primary constructor

This new syntax concern again the properties, you can set the property intial value when calling the method :


public class class1(int x, int y)
public int a {get;set;} =x;
public int b {get;set;} =y;

The syntax benefit is only at code line number, it’s better for understanding, but I think it will be useful.

dictionnary and indexed member initialization

Since  C# you can initialize dictionary  with a syntax not really intuitive :

var letters = new Dictionary<string, int>
{ « a », 1 },
{ « b », 2 },
{ « c », 3 },


Now there is two better way to initialize a dictionary :

var letters = new Dictionary<string, int>
[« a »] = 1,
[« b »] = 2,
[« c »] = 3,




var letters = new Dictionary<string, int>
$a = 1,
$b = 2,
$c = 3,


The second one, I think, will be very useful for json object

Thus, you can access to indexed value with the manner :


int a = letters.$a


 Declaration scope for variable

Until now, a variable only could be declared in autonom statement, not in the midlle of a function. But sometime, we only need a temporar variable result of tryparse for example. Now it’s possible :

if (Decimal.TryParse(txtPrice.Txt, out decimal price))
product.Price = price;


Filtering exception

in VB.NET it’s already possible, and now in c# 6 we can do that like in VB :

using (var stream = new FileStream(path, FileMode.OpenOrCreate, FileAccess.Write))

catch(IOException ex) if (ex.HResult == 0x80070020)
// File is in use by another process
// Handle that case…
catch(IOException ex) if (ex.HResult == 0x80070035)
// Network path was not found
// Handle that case…
catch(Exception ex)
// Something else happened
// Handle that case…

This method target to clarify code, it will be very usefull



As we can see, lot of new function has arrived, and lot of more will come. The new statement are not vital but they simpligy developper life.  If you want to show all news implementation visit this page

Throttling state

Use the following steps to access the performance counters.

On the Desktop, click Start, point to Programs, point to Administrative Tools, and then click Performance.

In the Performance dialog box, click Add.

In the Add Counters dialog box, from the Performance object drop-down list, select from the available BizTalk:Message Agent performance counters, and then click Add.

In the Add Counters dialog box, do one of the following:

After selecting the counters, click Add and then click Close.

For each Host instance,the throttlings state are shown with « Message delivery throttling state » and « Message publishing throttling state »

When there is no throttling, their values are 0. But when they got throttlhing state, their value could be 1 to 11

Here is their definition :

Message delivery throttling state A flag indicating whether the system is throttling message delivery (affecting XLANG message processing and outbound transports).

  • 0: Not throttling
  • 1: Throttling due to imbalanced message delivery rate (input rate exceeds output rate)
  • 3: Throttling due to high in-process message count
  • 4: Throttling due to process memory pressure
  • 5: Throttling due to system memory pressure
  • 9: Throttling due to high thread count
  • 10: Throttling due to user override on delivery
Message publishing throttling state A flag indicating whether the system is throttling message publishing (affecting XLANG message processing and inbound transports).

  • 0: Not throttling
  • 2: Throttling due to imbalanced message publishing rate (input rate exceeds output rate)
  • 4: Throttling due to process memory pressure
  • 5: Throttling due to system memory pressure
  • 6: Throttling due to database growth
  • 8: Throttling due to high session count
  • 9: Throttling due to high thread count
  • 11: Throttling due to user override on publishing

Then I wish you luck
